*Thanks for watching.* [VIDEO CONTAINS SOME GRAPHIC IMAGES] We return to our [HALF-LIFE HISTORIES] series with a story you probably haven't heard before. The Hanoi Incident is overshadowed in history by Anatoli Burgoski, but ask yourself a question...why was the fate of the anonymous director in Hanoi so different?
It completely blows my mind that there wasn't something as simple as a conspicuous red light in the room that was lit when the machine was turned on...
Or even just a door interlock. The irradiator I uses at work has a simple mechanical switch on the door into the room, such that the machine cannot be started unless the door is closed, and will immediately trip offline if the door is opened when in operation.
@@forceawakens4449 For sure. Any place with respectable safety measures the interlock would be a failsafe intended for if you already screwed up every other safety procedure and mechanism. And you'd be in serious trouble if you only avoided an accident due to the interlock. It'd still be an improvement in this case though.
Two things 1: this man is incredibly lucky it was only his hands in front of that beam. It’s really terrible it happened at all, but at least the human body can survive without hands. 2: “antimatter annihilation” is the hardest thing I’ve heard all day
@@offbrandbiscuit I watched a video about that a while back and went into it expecting the guy to be killed instantly Probably one of the craziest stories I’ve ever heard!
@@alamrasyidi4097that's true, some naturally occurring radioisotopes decay by beta plus decay (emitting a positron from the nucleus), but in this case the antimatter was created by photon scattering: A high energy photon (a very hard X or gamma particle) hitting a high intensity electromagnetic field (like the one of an atomic nuclei) can, with a certain probability depending on the energy of the photon (the higher the energy, the greater the probability) scatter (exchange momentum) by producing an electron-positron pair. The positron from the pair then quicky annihilates with any of the surrounding electrons, which emits two lower energy photons of exactly the same frequency and in the exactly opposing directions, the event which can be easily detected using scintillating crystal detectors.
@@offbrandbiscuitthat's mentioned in the video - the Russian guy was lucky, ironically, that his accelerator emitted a beam of particles of much higher energy which his tissue was not able to stop, so most of the particles passed through without making too much damage, plus I believe the beam was very narrowly focused.
"You've irradiated your hands!" "Oh. . . Damn, okay let me go check the on the radiation measuring device. . . Oh yep, there is antimatter embedded in me actively annihilating my organic tissue. I guess I'll go home"
"My hands are getting worse so I finally got medical treatment, but doc says it's probably a vitamin deficiency and they definitely know how particle accelerators work so I won't question their diagnosis. I guess I was wrong about the cause of my symptoms...it wasn't my arthritis."
As an accelerator physicist in Germany, I'm used to interlock systems, radiation bunkers, lead fortresses and the like. To think, that as late as the 1990's there were accelerator facilities with so low radiation protection standards anywhere in the world, is quite shocking to me.
It's a nuclear physics institute run by a post-starvation, post-blockade and nearly bankrupt Communist country that absolutely had other priorities than some weird nuclear scientist's demands. To think the country had such institutes is outlandish - kind of like hearing about Zambia having a space programme.
Can you then please explain to me what he's talking about in this video at 16:10 the part they "do a check for Antimatter annihilation", I think this part could be BS. Seems like a simple Geiger counter isn't what he means they used for checking if something was dosed. What does "Antimatter annihilation" even have to do with radiation exposure at that point?
the point is, you would never actually feel anything or realise anything at the moment any stream of particles or radiation pass through your body, nor your body would react to it immediately, no pain, no bite or tinging sensation. Its important to note that the beam dia of stream of particles in small scale accelerators is of few microns to less that a millimeter. If you dont know if the beam is active or not, you would never know if you hit or pass the beamline once or twice, or n number of times while working around it. It is the after effects, and scale of dosage (15:20) which decides the level of damage being done by the particle beam into the body tissues. Then you would realise that something happened to the skin and tissue a few days ago. If you know the beam is active, and you know the path of beamlines, and you still deliberately put your hand into the path, then its another story. But it would still feel like you are waving your hand in the void.
My friend had his hand surgically embedded in his abdomen like that after it got caught is the gears of a machine at a plastic factory, I'll never forget going to visit him and seeing that.... He had initially lost all but his pinky and ring finger and that side of his hand but they ended up having to amputate just above his elbow because of complications. He won a lawsuit against the company because the safety sensor on the machine didn't work and then he opened his own landscaping company called Captain Hooks lol.
I mean... They didn't just fall off, unless you wanna use the "I didn't shoot him, I just threw the bullet REALLY REALLY FAST" mental gymnastics. His hand cells just fell onto the scalpel. 😂🤣
The director's name is Trần Đức Thiệp (you can see his name at 13:22). He was and still is one of Vietnam's leading experts in atomic energy, and he is still healthy and well. He talked briefly about the incident in an interview, stating that (after being discharged from hospital and returning home) he initially struggled in performing daily activities but after a while he adapted to living life normally, even driving his motorbike like nothing had happened. He is a distinguished professor and still very much active in the field of nuclear physics even to this day.
@@yeos_angel_ he were in his younger day when safety standard was somewhat lacking, consider that in 1992 communist Vietnam has just opened up after the USSR collapse so go figure.
@@yeos_angel_ BREAKING NEWS, EXPERTS ARE ACTUALLY ONCE NEWBIES WHO HAD TO GO THROUGH TRIAL AND ERROR!!!! Please use your brain next time instead of asking dumb shit like that, jfc
imagine STICKING YOUR HAND IN A PARTICLE BEAM GOING THE SPEED OF LIGHT, and when your hand feels weird a few hours later, you just think, "Huh! Weird! Must be my arthritis."
As far as nuclear accidents go, the man was probably lucky. Losing both your hands is not cheap but far better than what has been covered by this channel in the past.
My best friend is a nuclear health physicist and the stories she has provided me are incredible. One of the most notable is the tsunami that hit Japan and caused the nuclear facility meltdown. The men that continued to work in that facility to minimize the catastrophe knew they were going to die as soon as they got irradiated, but they continued to work for the next 24 hours. They were basically walking corpses. These men were heroes. It was a painful death.
So were these unreported deaths? Because officially, there were no fatalities due to radiation contamination. Fuckishma is not chernobyl. Their reactors had containment structures that were much more robust.
What? At Fukushima there were zero deaths from acute radiation syndrome, and so far, 13 years later, there has been only one cancer death confirmed to be linked to the radiation.
Being a mere enthusiast who isn't even good at physics, I really can't state how much this channel has taught me about radiation. Thank you so much for the amazing content!
Same, I don’t fully understand all the maths and photon level stuff, but man it’s fascinating to me how a naturally occurring material can cause so much destruction to humans, not once or twice, but so many times
Whats even funnier is that uranium is actualy _the best_ material for stopping radiation because it is the most dense material we have. Edit: So apparently I am wrong and depleted uranium is not the single most dense material we have. However, it is still one of the most dense and it is also one of the most viable for construction because the other ones are too expensive or will kill you (lead specificaly).
@@kylehillDepleted Uranium is still radioactive, but the radiation levels are so low they're at or below background radiation in most of the world. Still DU plating and other items are always painted or otherwise coated, but that's mostly because Uranium Oxides are highly toxic (chemically), this also as a side effect blocks any alpha emissions.
On one side, you have some alpha particles and a little bit of gamma rays. On the other side you have lethal electron beams and X-rays. Which side do YOU want to be on?
“assuming that if you can’t feel something, nothing is happening” is such a dangerous idea. i can’t feel pain very well due to my medications (for nerve pain, so yes this is intended) but that also means i can’t feel infections until they’re severe. i had an abscess in my gums for 2 weeks before i realized since i just couldn’t feel the pain. it’s something everyone should learn, that just because something doesn’t hurt, doesn’t mean it’s all alright
Oh. I feel that. My brother I swear can’t feel pain. As a kid he would jump out his window onto the bush to play at night. He completely broke his pinkie and only went to the doc after showing mom it can now bend in this direction. And he also had an infection on his tooth and had to be removed. The stinker.
Same reason why we usually do Medical Check ups every few years. Just because you doesnt feel it doesnt mean there is some kind of Cancer growing in you. Do regular Check Ups Guys. There are People who would miss you.
@JaneFlowerbird cancer has telltale that aren't painful. If you're scared, go to a doctor (unless you live in the US, then chemio might be less costly)
I genuinely thought like this once, like perhaps living without pain would be nice, but then you’d never know what’s wrong with you. It’s like emotions too, it’s good you have them, like being sad or mad cause they tell you, you deserve better or things like what’s right and wrong.😅 Idk, I used to think heaven would be like you never get sad or feel pain but thinking about life like that seems kinda dumb. Like be thankful for your senses. 😂
I was born and raised in Hanoi, Vietnam. Accidentally, i found some your videos about radioactive energy. They actually widened my horizons. Even though I've lived in Hanoi since I was young, I just know this now. Thank you for your sharing useful knowledge
This video in particular is misleading. 90% of it is just radiation damage due to an xray machine which is found in every hospital and dental clinic. Not a particle accelerator.
1992 is literally just one year after Vietnam's economy started to take off. The poor equipment and protections for science were not something new, and back then they probably received very little budget. The crazy thing is this incident is literally unknown by the population. The news definitely tried to hide it as much as they could.
@@imbutter_s Same here. My co-worker watched this video and told me about it. My first reaction was thinking " we dont have a particle accelerator. Must be very recent". Nope, 1992.
tbf, it probably wasn't being hidden, one person slowly battling a disease that ultimately took 8 of their fingers isn't much of a news story. Even being due to a particle accelerator, I imagine the cultural understanding in the world in 1992 of particle accelerators was extremely low, no less a developing country.
The cabling and ducting in the "maze" (or labyrinth as we often call it in the industry) can be an absolute nightmare to deal with sometimes! The large coax and SWA cables can be awful to route and often require whole sections of the concrete blocks to be removed in order to install them...
This man needed immediate, aggressive interventions and grafts to begin replacing tissue in his hands with healthy tissue from other parts of his body before the existing, compromised cells reached end of life wear and required replacements from descendants that would be either highly dysfunctional, or not exist at all. Bone and muscle have slow enough turnover giving him precious time to act, unfortunately he decided that if he refused to grasp the gravity of what had happened and ignored it, it would all somehow go away.
@@SearinoxNavras Is that an actual medical procedure? Any idea what it's called? I can't find much about it via google & I thought grafts often fail with radiation damage.
Yep, I wonder what his thought process was....it's staggering that he was in charge, I wouldn't want him in charge of my coffee let alone that facility. It doesn't take a scientist or have any qualifications to know if you put your hands where they shouldn't be, i.e boiling water, acid, fire or anything radioactive then you're fucked, not oh well let's carry on!
I don’t rewatch TV shows, I just watch half-life histories on repeat. I have no idea why, but this is my comfort series. (Definitely has something to do with the immaculate craftsmanship)
Watching Kyle's videos, and the manner in which he presents all of the information that he does has made it very difficult to watch almost all of the other creators out there. Like you, I go back and watch them time and time again - sometimes picking up little tidbits that I missed the first time.
0:20 I love how the chart has an "Unknown" for the Rad level, like the people charting it all just got tired of walking and said 'fuk it, leave it blank' and just went home.
Having worked at CERN, I can basically tell you that it's like that. Or... More like a "We never checked, didn't need to so far, and it'd probably be annoyingly expensive to do so :P" Trust me, the radiation safety down there is a LOT better than this though.
You’re walking down the street when you see a guy with pirate hooks to replace his hands. He tells you his old hands were annihilated by anti-matter because he decided to mess with radioactive material without any precautions because he’s just that fearless. This is not a guy you mess with.
@@stephanekaufmann411 as a Vietnamese I'm not surprised. Stare run scientific labs are led by ignorant, skill-less people who had "connections" and wanted an easy yet still high paying job. In this case, this lab was just there to do experiments for the sake of doing experiments.
@@E.Hunter.Esquire No. If the assistant went it, it would have exposed the assistant as well. It’s faster and safer for everyone to run to the control room to turn off the machine than to waste time searching for someone and then having to explain to them their error as the machine continues to irradiate them.
i mean... the scientist himself took almost a month to look for help... that tells you a lot about their safety and health standards.. a scientist who studied particle accelerators decided to go "nah, ill be fine"
Kyle, haven’t had a chance to watch a Kyle video for a couple years. You have really hit the mark on content and quality. Way to go Kyle. Simple enough for the non-nukes to grasp but not oversimplified. The pace, voice, and graphics are spot on. It’s nice to see your number of subscribers has trended in the right direction as well.
"I can't read the manual. There's nothing in the room to tell me if the machine is on. We have no sensors to tell me if I'm being blasted with radiation anywhere in the facility. Maybe we should be cautious and think about this....nah, FIRE IT UP!"
@@brothercoconut6599 As if they would. All this stuff was specified in soviet manuals as well, and they also had all needed systems (even if they were not well maintained - watch another particle accelerator episode).
Do you remember that giant job fair America through the Vietnam job fair they spent a lot of money to get all these things built in Vietnam during the job fair like the deep sea port and the big are strips and now they have a lot of commercial money there and not too many concerns about OSHA or safety.
I thought I had somehow seen this video already, and then I realized I was just remembering the Anatoli Burgorski video. If I had a nickel for every time somebody stuck a body part in a particle accelerator I'd have two nickels which isn't a lot, but it's weird that it happened twice 😅
You may have seen the video from Plainly Difficult! about two years ago "A Brief History of: The Hanoi Electron Accelerator Accident (Documentary)" He includes the sources so you can read the reports. EDIT: There is a lot more info in PD's video and since he links to the reports, you can see it was more 'spicy' than this video makes it out. Also the director's name is known and appears in some of the photos.
Yeah, I thought this question was already answered by Comrade Bugorski. Please tell me this wasn't a "Hold m'beer" moment! EDIT: Having just watched the vid, I can safely conclude that the way the director handled his irradiation was infinitely more stupid than any "Hold m'beer" moment could ever hope to achieve. 🤦
I find it hilarious that I got an ad saying “if your happy and you know it clap your hands” right when you said the scientist lost both of his hands. The UA-cam algorithm has a fucked up sense of humor and I’m all here for it
Another factor contributing to the survival in the case of head injury is probably that the brain has little to no active cellular mitosis going on, so is far less susceptible to radiation damage. This can also explain the swelling mostly limited to the soft tissues and the bald spot on the back of the head.
Depends on the type of radiation. The brain is very sensitive to cellphone radiation, for example. Brain tumours are quite easily formed with overexposure - especially with children as their skulls are thinner/softer. I always have to cringe hard when a parent gives their young child a tablet or smart(dumb)phone.
@@Koozwadthere's a quite a bit of difference in intensity and frequency used on a typical mobile device compared to a particle accelerator, buddy. Best, An EE.
He dismissed his hand issues as arthritus after knowing he'd been irradiated in the hands? That is the craziest part of this story. If it was me I'd be at the hospital in 10 minutes max, but I'd also assume that literally everything that went even slightly bad was because my hands were trying to kill me now. 'caught a red light? must be the radiation. '
I completely agree with you, but I think it's also important to remember this was over 30 years ago, when the internet was still in its infancy, information wasn't nearly as readily available as it is today, and the safety culture surrounding nuclear engineering wasn't anywhere near as sophisticated as it is today. At that time, I doubt that anyone outside the USSR had even heard the name "Anatoli Burgorski" before, let alone knew what had happened to him.
@@bsnow304as someone who spends much of his time in Vietnam, not much has changed. Had someone that was rock climbing in ha long bay fall improperly into the water and was complaining of back pain. Brought to the local doctor and was told to take a nap and drink water. When this person got back to their home country x rays would show that his spine was fractured. The level of " walk it off ism" here is insane to me.
@@BotWhisperer wtf was he supposed to do? It's old Vietnam, hospitals won't be able to do shit about an irradiated limb other than just amputating it. So he just accepted his faith and went home
To be fair, it's really not that far fetched to think a doctor wouldn't have the slightest idea what that actually entails. They are DOCTORS not PHYSICISTS!
It's amazing how often both the victims and doctors involved initially dismiss radiation accidents like this as nothing serious at first, and only realize just how bad things are days or weeks later.
I think the fact that whatever happens from then on is inevitable anyway also plays a role in that, there's nothing they can do to reverse the irradiation, so there's no point doing anything except treat the symptoms as they appear, might as well try going on as normal as long as they have left to do so
Being a Vietnamese and this story was in the 1992, it not surprise me at all. Even though now we have safety measure but due to lack of resources and malpractices, accidents happens all the time.
One question. Why did the director and other staff not do anything until 24 days later, when his hand was falling apart? They were clearly extremely concerned when it happened. Was there just no point in intervening in an irradiation incident? And the annual checkup doctor 🤦🏻♀️ Referring him to a _dermatologist?_ Couldn't he have demanded an expert look at it, if the HINP didn't have one on hand? Edit: ok that was a bit more than one question.
@@destituteanddecadent9106 kyle did explain this in the video. "A developing country, using foreign machinary without manual with local language, lack of safety procedures, lack of resources". This incident probably the reason why my nation atomic technology never develop and probably never will. It a sad but true reality
@@DarkMagicianMan20 you surely do underestimate scientists and experts in this country doing their best for the sake of your people. Dalat Nuclear Research Institute is and will continue to carry out researches and supply radioisotopes and radiopharmaceuticals for hospitals throughout the country. Just please don't assume boldly the ability of other people based on your limited knowledge and spitting it as if those were the matter of facts
@@minhtoriwt I'm sorry if i offended you because my reply not stated clearly this is just my opinion. I didn't mean Vietnam not have ANYTHING to do with nuclear related research, but we still don't have the capability to build, maintain a nuclear reactor( this is what I mean in atomic tech). I trust many Vietnamese like me want our nation to forward our understanding of the atom. Also I use the word "Probably" so I still believed.
KYLE!!!! I teach radiography and this video is perfect for my students! The explanation of radiation protection is perfect! The graphs are on point for showing the levels of radiation compared to what they will be producing in the clinic! Thank you so very much for posting this content. A link is going on my LMS for them NOW!
Great job putting this together for what made for a super entertaining and factual presentation! My one playful nitpick as a radiation therapist who uses linear accelerators daily to treat cancer... This man technically did not put his hand in a particle accelerator, but rather in the high energy X-rays that are created from the speeding electrons interacting with the tungsten target. The true sense of placing something in the path of that particular particular accelerator would be to be exposed to the electron beam, which we do use in treating cancer as well. Electrons have a super low mass and as such they deposit their energy very superficially in tissue. We use this to our advantage in treating skin cancers and various other applications such as irradiating the bed of an excised tumor intra-operatively (in the operating room) using a portable linear accelerator electron beam. Just some random info for those fascinated by radiation. Again, great job man!
This really reminds me of the tuna canning incident. People don’t even think about safety until someone gets hurt. And even then, people forget why it’s important, and some poor rando has to pay for it.
Reminds me of a story I heard from an old employer (in the context of a safety brief). I used to work for the manufacturer of spiral conveyor belts - house-sized contraptions that move a conveyor along a circular path, usually either inside a blast freezer or a proofing oven. luckily in this accident no one got cooked or frozen unlike the tuna incident, but it was pretty grisly, so, fair warning: I'm about to describe an industrial accident, as it was described to me. The machine in question - the conveyor spiral - basically operates by winding the belt horizontally around a large metal cage like a spool of thread. The cage rotates, and the cage itself is actually what drives the motion of the belt - there is a central motor in it that turns it so that the belt is not under too much tension (rather than just pulling on the belt, which would snap it). but when you are installing the new belt, it's tricky to get it on - you can't just yank on it, you'll never be able to pull hard enough even if snapping the belt wasn't a concern. You have to get the cage turning at the same time as mild tension is applied to the belt to keep it from slipping off. And because this is a very big machine, you can't just do that from the outside and run around - it's too wide and tall. So you have to be up inside the cage to do this, and you need to have a couple of helpers manually turning the cage by hand, and this has to be pretty well coordinated. Apparently, from what I gather, the install team did not have helpers turning the cage manually. Instead, they just turned on the motor. But the thing about this motor is that it absolutely will not stop turning unless a tremendous force is applied to it. It's a low-speed, high torque motor meant to drive something that weighs at least a couple tons. If you catch a body part between the rotating cage and the stationary frame, the motor won't even hesitate to crush you. And that's exactly what happened - but it wasn't a body part, it was a whole torso. Apparently the person inside the cage and the person on the controls had not coordinated well enough, and the person inside was not fully inside when the motor went on - they were halfway through climbing up. I heard they got sliced fully in half, right across the midsection.
Thank you for these. As a former Nuc med tech, safety is pounded into our brains and we were not dealing with accelerators. It is also baffling that those literally studying the effects of the X-rays on a sample had so little concept of what there were dealing with. As you mentioned , if they can’t feel anything, nothing is happening…sigh.
Its not totally surprising that they didnt appreciate the necessity of all the structural and logistical safety issues as after all: theyre just procedural, structural and such at least one step removed. What i find totally baffling is that anyone competent enough to actually gain anything from particle acceleration research would not appreciate the need to go to a hospital immediately and instead takes a "wait and see" approach.
I have worked most of my career in radiation therapy. In the late 90’s I designed treatment rooms for Philips / Elekta linacs and in 2013-16 worked for Varian Proton Therapy. I was very interested by so much of this video and have subscribed to learn more from this channel. I have many photos and stories from my career but none match the stories that are shared here.
@@clanrobertrose8199 I don’t think it would be appropriate for me to say too much but, while radiation controls are usually very strict, it’s possible to make mistakes and, as in this video, radiation is a silent / invisible danger.i remember once designing a room for a hospital in the Middle East. They wanted much thinner concrete in the ceiling than I calculated. Their argument was that the hospital restaurant would be above the treatment rooms and people wouldn’t spend very long there. But what about the staff who work there everyday I asked. In the end, the customer and their architects are responsible for the building and for getting it approved as compliant to local regulations. I only gave advice based on the knowledge of our device’s performance / specifications.
Sorry, I still haven't gotten over the Therac-25 debacle and think you're supporting quackery. They've been trying to market ionizing radiation as a miracle cure for a long time. Still quackery. Oh, you have cancer, let's bombard your body with energy known to cause cancer. 🤷♂ Might as well be giving people calomel. And, OMG, we know so much more about cancer than you did when you were 'designing treatment rooms in the late '90s'. Radiation therapy should be illegal at this point. I can't even get a friggin percocet when I throw my back out but they're still irradiating people. Makes sense. Sorry to tell you the profession you devoted your life to is an utter joke. And I don't just mean radiation therapy, I mean medicine in general. I've been sick for two years with symptoms of PAI and AIT, not to mention PsA. They're still trying to figure out what I realized a year ago. They finally found that I have ILD so it should be easier to get the proper tests for the other stuff but probably won't be because doctors these days come out of med school as institutionalized sociopaths. They are quite literally taught not to listen to their patients. And one random blood test is about as scientific as ripping a fart, especially when you have an intermittent condition. I've had to become my own immunologist and treat my condition with supplements and the occasional steroid medication I have to beg, borrow or steal. I had a prescription for Albuterol for exercise induced asthma as a kid but my radiology report has been available to my physician for 3 weeks and still no prescription for Albuterol, let alone the medications I really should be taking to treat it, like Trelegy and Humira. I have glucose levels so low that I would pass out if I fasted. How is it they don't connect the dots when I tell them I cannot take a fasting blood test because I would pass out before I got there? How can they be so arrogant as to assume if they didn't see anything obviously abnormal with my adrenal glands that I couldn't possibly have PAI? This is not at all supported by the copious literature I have read on the subject and if they are waiting for me to have obvious damage to my adrenal glands to treat me, they're headed for a malpractice lawsuit. I had to show photos of bloody sputum to even get an Xray and in spite of telling my physician that I get tested for all kinds of stuff on a fairly regular basis because of my sexual habits and TB is one of them, she still sent me for a TB test. Completely blind to anything but the statistically most likely answer, which wasn't really that considering my last TB test was less than a year ago. I've been off my supplements and steroids for well over a week just so I can take a thyroid test and I feel like shit. If this doesn't give the results the doctor is looking for, I'm going to Mayo so I can see a real physician. And did the doctor bother to order a thyroglobulin antibody test? Of course fucking not. And when do I see her again? 2 months. I am on track to have only seen a physician twice this year with multiple active autoimmune diseases. Damn osteopaths think they know everything and can treat everything. All they really do is sit on their hands and make excuses for not treating you. Like, WTF did you think 'extreme fatigue' meant? Apparently that means I'm fine, lol. At this point I know more about autoimmune disorders than my hack of a physician ever will and the closest thing I ever had to med school was a year at optometry school.
One thing that has always fascinated me with radioactivity accidents (thankfully not this case because only his hands got hit) is the idea that you could see a flash, know you are a dead man walking, but feel zero pain at first. Thinking of incidents like the demon core accidents where the nuclear physicists were smart enough to know they had just been killed hundreds of times over but having to wait for the agonizing process of their body catching up to what their minds knew. If it were me I’d probably seek ways to remove myself painlessly on my own terms immediately, if I were, say, Slotkin.
Truly horrifying fate. I like to think at least some of them wanted to make their sacrifice useful to humanity, and so decided to let things run their course for the sake of scientific discovery
I’ve worked in the electrical distribution industry for 38 years dealing with voltages from 11,000v to 132,000v and have known a couple of engineers who have died similar to this. An electric arc flash from a fault at EHV voltages can burn at over 22,000 degree C, [the surface of the Sun burns at 5500 degrees C] But one of the most dangerous things associated with this is the microwave radiation blast that is produced along with it. If you are caught at close range in one of these Arc flashovers without protective clothing it is a death sentence. At close range The heat of the flash melts and vaporises metal, clothing and flesh. You receive 3rd degree burns over your body. But the trouble is that the radiation blast that is produced in effect microwaves and cooks your internal organs. So you are alive lying in your hospital bed, covered on burns and waiting to die as your internal organs slowly start to fail one by one. And there is nothing anyone can do about it. The last I knew one happened in the 1990s, an engineer I knew made an horrendous error, [he accidentally left some electrical test probes plugged to a 33,000volt circuit breaker housing] He turn the system back on so those exposed probes became live,…. The following day he went into the C/breaker housing to adjust a mechanism, he failed to notice the probes were still in and flashed over against their live terminals. The most awful thing was that he had a trainee with him and while being loaded into the ambulance he told the trainee that he knew he was going to die.
@@robg521 I think I part of what he was talking about in this situation is that you know you are dead but you feel perfectly fine. No pain or visible damage to the body, just the knowledge you are doomed.
@@SpaghettiEnterprisesI don't know if it's that exquisite I think at the end of the day you could tell people that they have no chance of surviving and they would still go through most of the treatments to try to survive
Wow, gotta say the intro is sick. Also surprises me that this is an incident happened where I was born (Hanoi) but Ive never heard of it, so thank you Kyle for bringing it to my attention. I know a high school teacher there who does nuclear physics, and he shared that he was actually going to study to become a nuclear scientist and helped the country build its first nuclear power plant, but after incidents like this one and the Chernobyl meltdown, the plan was cancelled due to concerns of safety and risks of meltdown. Very interesting video overall, looking forward to see whats next.
Never heard of this incident as well, but you can google the professor's name (13:20 - Trần Đức Thiệp). Maybe this is only known in nuclear physicists' circles.
Hearing the serious lack of safety controls and procedures in these accidents is always eye opening to me. I remember doing radiography (a form of non-destructive testing) at my facility once. Everyone but essential personnel were removed, even when the source was in its enclosure. Extra shielding was installed. Extra radiation monitoring was done both before and during movement of the source from enclosure to its testing target (the x-ray source was moved remotely along a track). Signage was placed on all entrances, announcements made over the announcing circuits both before and periodically during the testing. All personnel in the affected area had to wear additional dosimetery with audible alarms (our usual dosimetery was long-term passive devices read once a month) both during the tests and when the source was secured. And our usual dosimetry was read daily even though involved sending it to a separate building, precluding us doing any work while it was being read. You don't mess around when radiation is involved. Remember TDS - Time, Distance, Shielding? Well you can't do crap about Time and Distance if you have no knowledge at all about when and where the radiation is. And Shielding can be ineffective without *testing* it with radiation measurements to ensure it's doing what you think it's supposed to be doing.
I started watching half-life histories a while ago when I was working in a factory. I quit my job and got into a radiation therapy program. Currently I work as a radiation therapist and am halfway through medical dosimetry school. I can't express how much of an impact this channel and your videos have had on me. Great video as always, keep it up!
I was lucky enough to tour Fermilab (4 mile circle) in Batavia, Illinois and the beam just happened to be off when we were there. The tour lead showed us about 5 or 6 newer looking concrete blocks on the exterior wall and explained that the magnets had gotten out of sync and the particle burst out of the ring right through the containment tubes and surrounding magnets and ripped a hole out the original blocks from the wall. Blew me away there was so much power in a particle soooo small. C is really HUGE.
It is surprising that among the popular comments there is not a single one pointing out the fact of the error at 2:53 and beyond. The second term contains momentum p=mU, where U is speed. Therefore, even at near-light speed we find that the second term is “Approximately Equal” to the first. But not “Much More” than him.
Glad I found this comment. This bugged me, because in fact, the second term of the equation approaches the value of the first term as the speed approaches that of light. p^2c^2 = (mv)^2c^2 = (mc)^2c^2 = m^2c^2c^2 = m^2c^4
Momentum isn't mv at relativistic speeds - there's an extra dimensionless factor denoted by gamma, which increases dramatically as you get close to light speed. Gamma = 1/sqrt(1-v^2/c^2)
You can go stand in a particle beam at CERN. The north area fixed target beam lines produce pions from the SPS protons. They "turn off the beam" by putting a 2m long concrete block in way making the area safe to access. What the block actually does though is convert the pions into a muon beam. While standing in the beam you feel nothing but it is odd to mentally realize that something is passing through you with the only indication being the flashing lights on your detector electronics. It makes you feel very transparent, like the world isn't really real.
@@lynx4082 Triple spaces after a full stop _are_ highly unusual. His comment is informative though, with good spelling, grammar, capitalization and punctuation. I don't think it's worth criticizing, particularly when your own comment contains nothing of value and no punctuation to boot.
It’s like on BREAKING BAD where Gayle was saying Walt’s blue was 99% pure while his was 96%. He further told Gus “I know that 3% doesn’t sound like much but…IT IS!” I thought about that when Kyle was saying the LHC could only get 99.9999% speed of light.
I'm so happy you continued this series, it's by far my favourite of atomic documentaries. You don't waste time with exaggerating details for entertainment, because you understand the story and science behind it are exciting and immersive enough. Wonderful work, Kyle.
Small point: at 2:41 you have 'E = mc^2 + pc' on the screen, but 'E^2 = m^2 c^4 + p^2 c^2' doesn't simplify to that! The real simplification is setting 'p = 0' (which is basically true for non-relativistic speeds) and then E^2 = m^2 c^4 does simplify to E = mc^2
@@Astraeus.. I'm with @kikivoorburg on this one... the fact that it changes nothing to the rest of the video is itself completely irrelevant: the simplifaction is simply incorrect. Many people watch these videos, and those types of mistakes are remarkable common (I've seen these mistakes on many university-level math exams), despite it being the result of a very basic algebraic formula that everyone has heard of, namely that (a + b)² = a² + 2ab + b², and not just a² + b². So, I think it is at least necessary to mention this mistake in the comments... to be honest, I absolutely cringed when I saw that simplification made, especially on a Kyle Hill video, where he seems to be very cautious and thorough with the scientific explanation of everything going on.

I would add that the famous E = mc^2 is more correctly written as E_0 = mc^2 (where E_0 means energy at rest). To go from E^2 = m^2 c^4 + p^2 c^2 to E = m c^2 for p = 0, you would write it as E^2 = m^2 c^4 (1 + p^2 / (m^2 c^2)) and then expand sqrt(1 + x^2) for small values of x as sqrt(1 + x^2) ~= 1 + 1/2 x^2 + ... - which would lead to the classical equation E_k = 1/2 m v^2 for kinetic energy.
We be like that. Need to be held in check. I used to ride home in the same bus as an electrician working in my university's nucelar power plant. He joked about dropping his screwdriver into "that thing, tried to fish it out, but couldn't reach it, hahaha" he decided to not alert anyone, telling me "there's heaps of stuff down there"...
What university has a nuclear power plant? Seriously, if you're gonna BS people, at least do it right. The only nuclear reactor I've ever heard of at a university was the Chicago Pile back during the early days of the US nuclear project in WWII and it was quickly dismantled after they did their experiments. The only way they were even allowed to do it there was because there was a major war on. These days, fuggheddaboudit. The scary thing is they can work on inventing the quantum bomb with reckless abandon because universities definitely have particle accelerators. If a nuclear bomb only needs 10kg of plutonium, imagine how little mass is required on the quantum level to initiate a catastrophic chain reaction. Surprised there isn't a black hole swallowing us as I type.
@@Lurch-Bot sorry, no time to eead the hole post. The Johannes Gutenberg University in Mainz, Germany, has a nuclear thingy on its campus. It's no secret, google it.
I would never expect seeing Vietnam in Kyle Hills video, not the literal city where I was born and its not about Pho but about partical accelerator accident??? This is so cool
I live in Vietnam, so from what i called, the things with regulations and policies for safety didnt apply much for our people back in the days. Especially back when Vietnam was just gotten out of a huge major war and Economy still try to recover itself. Everything we did was trying our best to getting back on track to live and having a better life, knowing that it would cost us life and many things else. And for us people, we usually joking about our braveness is on the top list since we were use to cutting bomb to sell scrap and gunpowder also. So yeah, long story short, it such an honor living in a country like that but also sometimes scary af 😅
I wouldn't call the early '90s 'just getting out of a war'. Your war had been over for almost 2 decades when this happened. The fact is that there is a lax attitude towards safety in your country that is evident still today. All I gotta do is watch a Vietnamese motorcycling video to see that. Enjoy. Ignorance is bliss. The fact is that a communist government will never value human life as much as a capitalist one. You took your cues from the Soviet Union and China. A quick study of history will tell you they thought nothing of murdering people en masse to hold power. Even to this day, Russia is still sending human waves against superior troops. That might work when your back is against the wall but they didn't have to invade Ukraine. Putin is just trying to put the Soviet Union back together and his methods speak volumes to that. He would never fire his nukes at anyone simply because his own people would have him hung, drawn and quartered, assuming anyone was left after the retaliatory strike. And, unlike the old Soviet garbage they're using, our nukes would actually mostly work, instead of mostly being duds. Part of the reason their crap is so unreliable is because a lot of those Soviet subjects engaged in sabotage. And it was cheaply designed in the first place. They definitely didn't expect designs from the '50s to be fighting a war 70 years later. I will say that it was not America's place to get involved in your civil war. I will also say that the wrong side won and I think the outcome would have been different if there were never any US troops sent to Vietnam. We handed the communists the win just by getting involved. We are still facing the consequences of meddling in China's civil war today, however I am sure a lot of people in Taiwan are glad we did. But we sealed our own fate by not continuing on to Siberia when we got to Berlin in WWII. The simple fact is that the Soviet Union never should have lasted long enough to have a Cold War, or to corrupt Vietnam with their inhumane ways. You just traded one inhumane dictator (the French) for another. Imperialism comes in many forms and it is most insidious when perpetrated against one's own people. After all, we never tortured any of your people but you did not extend the same courtesy. It is dishonorable. Chances are you have zero idea what really happened at the Hanoi Hilton. You are still subject to anti-American propaganda, even as you pretend to extend diplomatic and trade courtesies. And when I say torture, I don't mean a rap on the head or bright lights, or even waterboarding. I mean torture solely for the purpose of making people suffer as much as possible. Killing them slowly. That's your legacy, next to which carpet bombing empty jungles or even Agent Orange dispersal pales in comparison. We were fighting a difficult war against an insidious enemy. But your side took it out on people who couldn't even run, often because they had been hobbled (deliberately shattering someone's ankles so they can never run again), but mostly because they were captive. Only the lowest excuse for humanity would do such things. What the US did to Vietnam pales in comparison to what numerous communist regimes have done to their own people. And the Soviets put more people in concentration camps than the Nazis could ever imagine. They treated the Jews as badly; millions died in numerous pogroms. While Germany and Japan are tales of redemption, Russia is just still holding on to the old ways. They never got what they truly deserved but if they keep fighting with Ukraine, they definitely will. The EU is moving to admit them as a means to stop the war. If Putin persists, beyond a certain point, he will be facing WWIII but this time Russia won't be on the winning side. China is a paper tiger. Doesn't matter about numbers these days. 200 awesome stealth fighters are better than 2000 crappy ones. When you start to impress civilian ferries into military service because you didn't plan for the thing you've been threatening for 70 years, it isn't a threat, it is just sad and pathetic. Like Kim Jong Un and his big missile. Just compensating for an inferiority complex, a common thread among Communist dictators. What I really don't get is how people could think a government in which they have no say is a good thing. And Vietnam has yet to learn the meaning of freedom. Do yourself a favor and don't make excuses for the fact your Communist government is lax on safety when you have no leg to stand on; don't even really know history. Especially not on UA-cam.
@@Lurch-Bot tldr btw 😳 and when it comes to safety guidelines nowadays, much more better than before. And tbh, Vietnam just got out of the Trade Embargo by the fking Murica in the late 90s, before that, war in our country actually ended in the 80s again the Chinese and Cambodian. Just saying, if you really are that good and well understanding then come to our “communist country” and live rather than just trash talking 🫣
This is superb. I am a radiation worker and have worked with radiation safety systems. This video would be much better training for the workers than what we get! No one knows the work that goes into protection- the shielding calculations and verification, the interlocks and the procedures.
Also going over the lack of concern and procedure this sounds like a case of the people involved not knowing what they are doing and not knowing the implications of what they are doing and just simply doing as they are told on the job. This is what a competency crisis is.
What beats me, is that nobody translated the papers from Russian. There were many Vietnamese scientists and other workers in Soviet Union; Vietnam sided with USSR to ward off China. Many must have known Russian at high proficiency. I also find it hard to believe that at least some of the Vietnamese scientists hadn't studied in USSR
Once upon a time, many years ago, I got to go along on a private tour of the Stanford Linear Accelerator, given by one of the top Physicists to a Physicist who was working on an Accelerator in Australia (who happened to be my father's cousin's husband). At one point they got talking technical, using many words that I couldn't begin to fathom, and then remembered that I was standing there with them, and they apologized to me. And I honestly told them no apology was needed. I didn't understand what they were saying, but I could hear and see their passion and excitement, and it was awesome! I mention that story to say this: You are a science communicator helping us mere-mortals understand and appreciate the magic of science, but; perhaps one day you could give us an undiluted video of something where you talk-tech were you allow us to be confused by the tech-talk. I know it's still a cherished moment for me, even though I don't remember any of it. (I think maybe they talked quarks and then got smaller, maybe.) As always, thank you so very much for the videos.
May i ask as an American, why do the Vietnam people write English so well? Every Vietnamese comment under this video has spot on English! Very impressive.
@@kyledodson2992 While it's true that the younger generations of Vietnameses have familiarized themselves with English to a great degree, in the specific case of this comment section it's more about sampling bias than anything else. People without a sufficient degree of English proficiency wouldn't go out of their way to watch an English video about nuclear physics after all, and having a video about Vietnam would surely draw out the English-capable Vietnameses within the population of viewers.
I really liked this style video. serious and extremely informative but not overacted and overanimated like some of the other video's. This video almost felt like it was intented for a different audience. Keep em comming Thank you!
Every goddamn time i'm sitting in my chair, screaming at my desktop for how simple most of these incidents seem to be preventable from a today's point of knowledge. Yet dismissing your hand feeling 'weird' for your arthritis instead of THE RADIATION BEAM YOU GOT THIS MORNING is infuriatingly ignorant. Ngl, i find it hard to sympathise. Not that i'm not sympathising, but this guy makes it real hard for me is all i'm saying.
@@dimitrilepain3821Not necessarily ignorance. The guy was just coping and hoping what he felt was a psychological problem or anxiety rather than admit the worst. And for some reason, Asians hate going to the doctors. For an Asian at that time, things would have to be seriously wrong to go for a doctor visit.
@@hx5525 "The guy was [...] hoping that what he felt was a psychological problem [...] rather than admit the worst." That is literally ignorance.

Hey Kyle! As a (advanced) layperson I really enjoy the way you seem to accurately represent these various nuclear incidents. It's also very cool how you make it clear when you know exactly what you are talking about or otherwise Here's some interesting incidents I found that I am not aware of any of your videos addressing: Tokaimura nuclear accident 1999 Kyshtym disaster 1957 Windscale Piles fire 1957 SL-1 nuclear meltdown 1961 (Army) SL-2 reactor accident 1961 (AEC) The first one sounds most interesting The SL 1 and 2 incidents could be exceptionally suitable for a UA-cam format. It gets the curiosity going and I have so many obvious questions Thanks dude, for everything. All of the science presenters I grew up with really seem to like you and are eager for you to continue their legacy
Small correction I have to make. Einstein's equations do not outlaw faster than lightspeed travel. They only say it is impossible to travel precisely at the speed of light. It just is not known if it is theoreticly possible to brake that barrier.
Logically, if you cannot travel at exactly the speed of light, you cannot travel faster than it. Because you have to accelerate through the exact speed of light to reach any speed higher than that - so at some point you will be exactly traveling at the speed of light. Which is impossible.
@@Sir_Cactus It's entirely the point. If you can't travel at the speed of light, you can't travel faster than it either. Therefore it is indeed theoretically impossible to break the lightspeed barrier. Now, there may be ways to bend the rules, or to cheat physics - for example, the Alcubierre metric. But as to actually breaking the speed of light through brute force acceleration? Nah, that's not going to happen.
@@vicroc4 There is still a lot about the universe we do not know and there are lots of open questions. What if something has been travelling faster than c from the very beginning of time.
it never ceases to amaze me how scary radiation is.... exactly because of it's stealthiness and how people get used to it and forget to be cautious around this beast (no shade, i know i would get careless, it's sadly natural when something becomes routine)
I'm Vietnamese, born and living in Hanoi. But this is literally the first time I heard there is a particle accelarator in my country, let alone this story. Truly each day is a chance to learn something new.
insane considering how old and worn down the atomic institute building is, let alone the fact that such building even store a fucking particle accerelator.
I will never understand the science behind any of this but the way you describe it is incredible and gives me the slightest glimpse into what everything means!
It's honestly great that you point out that this incident occurred primarily due to human error, not because of the nature of radiation itself. It would be great if more people were aware of these details in regards to these types of incidents.
I just can’t imagine how stressful it must have been to think “Maybe I can save my left hand” one day to then seeing the necrosis come back… it’d been toying with your emotions 😢
This just reinforces to me that if I (somehow) ever get an irritated limb, I'd want it amputated quickly. I'm not dealing with long term molecular damage, thank you.
My dad worked there and that case was famous. His motorbike later transformed to be used with his left hand. My dad was the one who brought by him self the box containing radioactive material from that institute to another one in Dalat by train. There is another case when a scientist fell on stares while bringing a big acid tank with another in the Chemical Institute.
The Director's name can be seen written next to the photos of his hands: Tran Duc Thiep. From what I can find, he's still alive and still works in the field.
@@condor2279 Oh I see! Yes, I recently did a video call for work with an overseas gentleman as well and I realised he only has half of his left hand's index finger. A decorated museum curator at 75. A wonderful person.
I work with nuclear submarines and I absolutely LOVE these videos. Very much brings perspective and grounds thought processes of normal everyday work upon a nuclear plant and is an important reminder of why there are such stringent work controls and standards where I work. Thank you for the educational and entertaining videos!
I worked in a steel mill for 17 years as an instrument technician. One of our process engineers was working with an x-ray gauge we used for thickness measurement. The source was exposed when his head was in the path, a month or so later he had a tumor the size of a baseball in his brain he never recovered from. You can't mess with this stuff and expect to come out of it ok.

Or even just a door interlock. The irradiator I uses at work has a simple mechanical switch on the door into the room, such that the machine cannot be started unless the door is closed, and will immediately trip offline if the door is opened when in operation.

@@AsobiMedio tfw u dont even watch the whole video
@@forceawakens4449 For sure. Any place with respectable safety measures the interlock would be a failsafe intended for if you already screwed up every other safety procedure and mechanism. And you'd be in serious trouble if you only avoided an accident due to the interlock. It'd still be an improvement in this case though.
Two things
1: this man is incredibly lucky it was only his hands in front of that beam. It’s really terrible it happened at all, but at least the human body can survive without hands.
2: “antimatter annihilation” is the hardest thing I’ve heard all day
some radioactive decay are known to emmit antimatter particles. i guess thats the radiosignature they detected in his hands
A Russian scientist had a particle beam pass through his brain but still somehow survived, shit is insane
@@offbrandbiscuit I watched a video about that a while back and went into it expecting the guy to be killed instantly
Probably one of the craziest stories I’ve ever heard!
@@alamrasyidi4097that's true, some naturally occurring radioisotopes decay by beta plus decay (emitting a positron from the nucleus), but in this case the antimatter was created by photon scattering: A high energy photon (a very hard X or gamma particle) hitting a high intensity electromagnetic field (like the one of an atomic nuclei) can, with a certain probability depending on the energy of the photon (the higher the energy, the greater the probability) scatter (exchange momentum) by producing an electron-positron pair. The positron from the pair then quicky annihilates with any of the surrounding electrons, which emits two lower energy photons of exactly the same frequency and in the exactly opposing directions, the event which can be easily detected using scintillating crystal detectors.
@@offbrandbiscuitthat's mentioned in the video - the Russian guy was lucky, ironically, that his accelerator emitted a beam of particles of much higher energy which his tissue was not able to stop, so most of the particles passed through without making too much damage, plus I believe the beam was very narrowly focused.
Honestly the fact that somebody losing their hands is one of the worst particle accelerator incidents in history is pretty good.

As an accelerator physicist in Germany, I'm used to interlock systems, radiation bunkers, lead fortresses and the like. To think, that as late as the 1990's there were accelerator facilities with so low radiation protection standards anywhere in the world, is quite shocking to me.
Vietnam is a 3rd world country. That means it's decades behind and accepting second hand equipment.
It's a nuclear physics institute run by a post-starvation, post-blockade and nearly bankrupt Communist country that absolutely had other priorities than some weird nuclear scientist's demands.

As someone who has a short attention span,
Can you then please explain to me what he's talking about in this video at 16:10 the part they "do a check for Antimatter annihilation", I think this part could be BS. Seems like a simple Geiger counter isn't what he means they used for checking if something was dosed. What does "Antimatter annihilation" even have to do with radiation exposure at that point?
Bro got his hands irradiated, went home and they felt weird, and he was like "nah it's not the radiation, probably the arthritis"
the point is, you would never actually feel anything or realise anything at the moment any stream of particles or radiation pass through your body, nor your body would react to it immediately, no pain, no bite or tinging sensation. Its important to note that the beam dia of stream of particles in small scale accelerators is of few microns to less that a millimeter. If you dont know if the beam is active or not, you would never know if you hit or pass the beamline once or twice, or n number of times while working around it. It is the after effects, and scale of dosage (15:20) which decides the level of damage being done by the particle beam into the body tissues. Then you would realise that something happened to the skin and tissue a few days ago.
If you know the beam is active, and you know the path of beamlines, and you still deliberately put your hand into the path, then its another story. But it would still feel like you are waving your hand in the void.

He had initially lost all but his pinky and ring finger and that side of his hand but they ended up having to amputate just above his elbow because of complications. He won a lawsuit against the company because the safety sensor on the machine didn't work and then he opened his own landscaping company called Captain Hooks lol.

imagine STICKING YOUR HAND IN A PARTICLE BEAM GOING THE SPEED OF LIGHT, and when your hand feels weird a few hours later, you just think, "Huh! Weird! Must be my arthritis."
Sounds more like denial, to me. To be fair though, what were they going to do with earlier diagnosis? What other treatments?
Then when it start to rot from the inside ... "have some vitamins!"
That's just what having chronic illness is like tbh. It's hard to gauge when something is unusually wrong if pain/discomfort is your baseline.
Exaggerate much? It's only like 99.999999879% of the speed of light.
I can understand the doc not knowing what to do since radiation wasn’t that well known at the time, but, um. His hands are black…
As far as nuclear accidents go, the man was probably lucky. Losing both your hands is not cheap but far better than what has been covered by this channel in the past.
Yup. Imagine if he had put his head down there to "eye-ball" it.
He would have had his brain leaking from his ears and nose within an hour.

@@MySerpentinehe got lucky that his head was too soft to stop the particle. If it did deliver the full radioactive payload he would be extremely dead.

I’m pretty sure dying is cheaper than losing both of your hands.
My best friend is a nuclear health physicist and the stories she has provided me are incredible. One of the most notable is the tsunami that hit Japan and caused the nuclear facility meltdown. The men that continued to work in that facility to minimize the catastrophe knew they were going to die as soon as they got irradiated, but they continued to work for the next 24 hours. They were basically walking corpses. These men were heroes. It was a painful death.
So were these unreported deaths? Because officially, there were no fatalities due to radiation contamination. Fuckishma is not chernobyl. Their reactors had containment structures that were much more robust.
This is anti-nuclear propaganda. As of 2024, no one has died directly from radiation exposure at Fukushima.
This is anti-nuclear propaganda. As of 2024, no one has died directly from radiation exposure during the Fukushima disaster.
What? At Fukushima there were zero deaths from acute radiation syndrome, and so far, 13 years later, there has been only one cancer death confirmed to be linked to the radiation.
This is false. Only one person died from radiation from the accident and that was 4 years later so hardly a "walking corpse"
Being a mere enthusiast who isn't even good at physics, I really can't state how much this channel has taught me about radiation. Thank you so much for the amazing content!

Same, I don’t fully understand all the maths and photon level stuff, but man it’s fascinating to me how a naturally occurring material can cause so much destruction to humans, not once or twice, but so many times
Ditto!
11:40 I know not all Uranium is radio active, but the idea of using Uranium to block radiation is still very funny to me.
I mean, technically, all Uranium is radioactive, but so is every element from Bismuth or heavier.
*depleted
Whats even funnier is that uranium is actualy _the best_ material for stopping radiation because it is the most dense material we have.
Edit: So apparently I am wrong and depleted uranium is not the single most dense material we have. However, it is still one of the most dense and it is also one of the most viable for construction because the other ones are too expensive or will kill you (lead specificaly).
@@kylehillDepleted Uranium is still radioactive, but the radiation levels are so low they're at or below background radiation in most of the world.
Still DU plating and other items are always painted or otherwise coated, but that's mostly because Uranium Oxides are highly toxic (chemically), this also as a side effect blocks any alpha emissions.
On one side, you have some alpha particles and a little bit of gamma rays. On the other side you have lethal electron beams and X-rays. Which side do YOU want to be on?
“assuming that if you can’t feel something, nothing is happening” is such a dangerous idea.
i can’t feel pain very well due to my medications (for nerve pain, so yes this is intended) but that also means i can’t feel infections until they’re severe. i had an abscess in my gums for 2 weeks before i realized since i just couldn’t feel the pain.
it’s something everyone should learn, that just because something doesn’t hurt, doesn’t mean it’s all alright
Oh. I feel that. My brother I swear can’t feel pain. As a kid he would jump out his window onto the bush to play at night. He completely broke his pinkie and only went to the doc after showing mom it can now bend in this direction. And he also had an infection on his tooth and had to be removed. The stinker.
Same reason why we usually do Medical Check ups every few years.
Just because you doesnt feel it doesnt mean there is some kind of Cancer growing in you.
Do regular Check Ups Guys. There are People who would miss you.
Aaand now I’m back to having anxiety about having cancer in my ovaries…..
@JaneFlowerbird cancer has telltale that aren't painful. If you're scared, go to a doctor (unless you live in the US, then chemio might be less costly)
I genuinely thought like this once, like perhaps living without pain would be nice, but then you’d never know what’s wrong with you.
It’s like emotions too, it’s good you have them, like being sad or mad cause they tell you, you deserve better or things like what’s right and wrong.😅
Idk, I used to think heaven would be like you never get sad or feel pain but thinking about life like that seems kinda dumb. Like be thankful for your senses. 😂
I was born and raised in Hanoi, Vietnam. Accidentally, i found some your videos about radioactive energy. They actually widened my horizons. Even though I've lived in Hanoi since I was young, I just know this now. Thank you for your sharing useful knowledge
This video in particular is misleading. 90% of it is just radiation damage due to an xray machine which is found in every hospital and dental clinic. Not a particle accelerator.
Vietnam is great. I have a date with a Vietnamese scientist soon.
1992 is literally just one year after Vietnam's economy started to take off.
The poor equipment and protections for science were not something new, and back then they probably received very little budget.
The crazy thing is this incident is literally unknown by the population. The news definitely tried to hide it as much as they could.
I'm Vietnamese and I didn't even know we had particle accelerators...
@@imbutter_s Same here. My co-worker watched this video and told me about it. My first reaction was thinking " we dont have a particle accelerator. Must be very recent". Nope, 1992.
Honestly if a country isn't well off enough to comfortably fully fund it, they shouldn't be spending money on stuff like this
tried so hard to find news about the incident but the only thing found was a foreign report :(
tbf, it probably wasn't being hidden, one person slowly battling a disease that ultimately took 8 of their fingers isn't much of a news story. Even being due to a particle accelerator, I imagine the cultural understanding in the world in 1992 of particle accelerators was extremely low, no less a developing country.
The cabling and ducting in the "maze" (or labyrinth as we often call it in the industry) can be an absolute nightmare to deal with sometimes! The large coax and SWA cables can be awful to route and often require whole sections of the concrete blocks to be removed in order to install them...
and worse, depending on the cabling the angles may be limited, requiring more complex duct designs.
Man was told he put his hands in while the machine was on.
"Ugh my hands feel weird. Must be that damn arthritis acting up again"
Damn you arthritis!
He even measured himself to be radioactive!
This man needed immediate, aggressive interventions and grafts to begin replacing tissue in his hands with healthy tissue from other parts of his body before the existing, compromised cells reached end of life wear and required replacements from descendants that would be either highly dysfunctional, or not exist at all. Bone and muscle have slow enough turnover giving him precious time to act, unfortunately he decided that if he refused to grasp the gravity of what had happened and ignored it, it would all somehow go away.
@@SearinoxNavras Is that an actual medical procedure? Any idea what it's called? I can't find much about it via google & I thought grafts often fail with radiation damage.
Yep, I wonder what his thought process was....it's staggering that he was in charge, I wouldn't want him in charge of my coffee let alone that facility. It doesn't take a scientist or have any qualifications to know if you put your hands where they shouldn't be, i.e boiling water, acid, fire or anything radioactive then you're fucked, not oh well let's carry on!

I really like these more seriously narrated videos you do. I can fall asleep to them with how calm your voice is.
Another factor contributing to the survival in the case of head injury is probably that the brain has little to no active cellular mitosis going on, so is far less susceptible to radiation damage. This can also explain the swelling mostly limited to the soft tissues and the bald spot on the back of the head.
Great point
So the brain doesn't really grow anymore or something and that prevents radiation damage from spreading?
I was thinking this at first as well. Never knew about the different displacement of energy between types of beams; very interesting stuff.
Depends on the type of radiation. The brain is very sensitive to cellphone radiation, for example. Brain tumours are quite easily formed with overexposure - especially with children as their skulls are thinner/softer. I always have to cringe hard when a parent gives their young child a tablet or smart(dumb)phone.
@@Koozwadthere's a quite a bit of difference in intensity and frequency used on a typical mobile device compared to a particle accelerator, buddy.
Best,
An EE.
He dismissed his hand issues as arthritus after knowing he'd been irradiated in the hands? That is the craziest part of this story.
If it was me I'd be at the hospital in 10 minutes max, but I'd also assume that literally everything that went even slightly bad was because my hands were trying to kill me now. 'caught a red light? must be the radiation. '
And the doctor recommended vitamins when he mentioned he'd probably been irradiated?
I completely agree with you, but I think it's also important to remember this was over 30 years ago, when the internet was still in its infancy, information wasn't nearly as readily available as it is today, and the safety culture surrounding nuclear engineering wasn't anywhere near as sophisticated as it is today. At that time, I doubt that anyone outside the USSR had even heard the name "Anatoli Burgorski" before, let alone knew what had happened to him.
Denial is a powerful feeling. He didn’t think it was a big deal. Or if he did he easily to stupid to understand.

It's amazing how often both the victims and doctors involved initially dismiss radiation accidents like this as nothing serious at first, and only realize just how bad things are days or weeks later.
I think the fact that whatever happens from then on is inevitable anyway also plays a role in that, there's nothing they can do to reverse the irradiation, so there's no point doing anything except treat the symptoms as they appear, might as well try going on as normal as long as they have left to do so
Being a Vietnamese and this story was in the 1992, it not surprise me at all. Even though now we have safety measure but due to lack of resources and malpractices, accidents happens all the time.
Just do things the familiar way you've always done, standards and procedures be all damned ;p Such is the Vietnamese style.
One question. Why did the director and other staff not do anything until 24 days later, when his hand was falling apart? They were clearly extremely concerned when it happened. Was there just no point in intervening in an irradiation incident?
And the annual checkup doctor 🤦🏻♀️ Referring him to a _dermatologist?_ Couldn't he have demanded an expert look at it, if the HINP didn't have one on hand?
Edit: ok that was a bit more than one question.

Great job putting this together for what made for a super entertaining and factual presentation!
My one playful nitpick as a radiation therapist who uses linear accelerators daily to treat cancer... This man technically did not put his hand in a particle accelerator, but rather in the high energy X-rays that are created from the speeding electrons interacting with the tungsten target.
The true sense of placing something in the path of that particular particular accelerator would be to be exposed to the electron beam, which we do use in treating cancer as well.
Electrons have a super low mass and as such they deposit their energy very superficially in tissue. We use this to our advantage in treating skin cancers and various other applications such as irradiating the bed of an excised tumor intra-operatively (in the operating room) using a portable linear accelerator electron beam.
Just some random info for those fascinated by radiation. Again, great job man!
Im just imagining strolling into a dermatologists office and saying "heeey so my hands where irradiated and I was told to come see you"
This really reminds me of the tuna canning incident. People don’t even think about safety until someone gets hurt. And even then, people forget why it’s important, and some poor rando has to pay for it.
Every safety law is written in blood.
Googled it; shouldn’t have done. At least I know what my nightmares will be about tonight 😳
Reminds me of a story I heard from an old employer (in the context of a safety brief). I used to work for the manufacturer of spiral conveyor belts - house-sized contraptions that move a conveyor along a circular path, usually either inside a blast freezer or a proofing oven. luckily in this accident no one got cooked or frozen unlike the tuna incident, but it was pretty grisly, so, fair warning: I'm about to describe an industrial accident, as it was described to me.
The machine in question - the conveyor spiral - basically operates by winding the belt horizontally around a large metal cage like a spool of thread. The cage rotates, and the cage itself is actually what drives the motion of the belt - there is a central motor in it that turns it so that the belt is not under too much tension (rather than just pulling on the belt, which would snap it). but when you are installing the new belt, it's tricky to get it on - you can't just yank on it, you'll never be able to pull hard enough even if snapping the belt wasn't a concern. You have to get the cage turning at the same time as mild tension is applied to the belt to keep it from slipping off. And because this is a very big machine, you can't just do that from the outside and run around - it's too wide and tall. So you have to be up inside the cage to do this, and you need to have a couple of helpers manually turning the cage by hand, and this has to be pretty well coordinated.
Apparently, from what I gather, the install team did not have helpers turning the cage manually. Instead, they just turned on the motor. But the thing about this motor is that it absolutely will not stop turning unless a tremendous force is applied to it. It's a low-speed, high torque motor meant to drive something that weighs at least a couple tons. If you catch a body part between the rotating cage and the stationary frame, the motor won't even hesitate to crush you. And that's exactly what happened - but it wasn't a body part, it was a whole torso. Apparently the person inside the cage and the person on the controls had not coordinated well enough, and the person inside was not fully inside when the motor went on - they were halfway through climbing up. I heard they got sliced fully in half, right across the midsection.
@@transcyberism1459 Fucking hell.
Thank you for these. As a former Nuc med tech, safety is pounded into our brains and we were not dealing with accelerators. It is also baffling that those literally studying the effects of the X-rays on a sample had so little concept of what there were dealing with. As you mentioned , if they can’t feel anything, nothing is happening…sigh.
Its not totally surprising that they didnt appreciate the necessity of all the structural and logistical safety issues as after all: theyre just procedural, structural and such at least one step removed.
What i find totally baffling is that anyone competent enough to actually gain anything from particle acceleration research would not appreciate the need to go to a hospital immediately and instead takes a "wait and see" approach.
I have worked most of my career in radiation therapy. In the late 90’s I designed treatment rooms for Philips / Elekta linacs and in 2013-16 worked for Varian Proton Therapy. I was very interested by so much of this video and have subscribed to learn more from this channel. I have many photos and stories from my career but none match the stories that are shared here.
How many ended up with radiation poisoning ?.
@@clanrobertrose8199 I don’t think it would be appropriate for me to say too much but, while radiation controls are usually very strict, it’s possible to make mistakes and, as in this video, radiation is a silent / invisible danger.i remember once designing a room for a hospital in the Middle East. They wanted much thinner concrete in the ceiling than I calculated. Their argument was that the hospital restaurant would be above the treatment rooms and people wouldn’t spend very long there. But what about the staff who work there everyday I asked. In the end, the customer and their architects are responsible for the building and for getting it approved as compliant to local regulations. I only gave advice based on the knowledge of our device’s performance / specifications.
Sorry, I still haven't gotten over the Therac-25 debacle and think you're supporting quackery. They've been trying to market ionizing radiation as a miracle cure for a long time. Still quackery. Oh, you have cancer, let's bombard your body with energy known to cause cancer. 🤷♂
Might as well be giving people calomel.
And, OMG, we know so much more about cancer than you did when you were 'designing treatment rooms in the late '90s'. Radiation therapy should be illegal at this point. I can't even get a friggin percocet when I throw my back out but they're still irradiating people. Makes sense.
Sorry to tell you the profession you devoted your life to is an utter joke. And I don't just mean radiation therapy, I mean medicine in general. I've been sick for two years with symptoms of PAI and AIT, not to mention PsA. They're still trying to figure out what I realized a year ago. They finally found that I have ILD so it should be easier to get the proper tests for the other stuff but probably won't be because doctors these days come out of med school as institutionalized sociopaths. They are quite literally taught not to listen to their patients. And one random blood test is about as scientific as ripping a fart, especially when you have an intermittent condition.
I've had to become my own immunologist and treat my condition with supplements and the occasional steroid medication I have to beg, borrow or steal. I had a prescription for Albuterol for exercise induced asthma as a kid but my radiology report has been available to my physician for 3 weeks and still no prescription for Albuterol, let alone the medications I really should be taking to treat it, like Trelegy and Humira. I have glucose levels so low that I would pass out if I fasted. How is it they don't connect the dots when I tell them I cannot take a fasting blood test because I would pass out before I got there? How can they be so arrogant as to assume if they didn't see anything obviously abnormal with my adrenal glands that I couldn't possibly have PAI? This is not at all supported by the copious literature I have read on the subject and if they are waiting for me to have obvious damage to my adrenal glands to treat me, they're headed for a malpractice lawsuit.
I had to show photos of bloody sputum to even get an Xray and in spite of telling my physician that I get tested for all kinds of stuff on a fairly regular basis because of my sexual habits and TB is one of them, she still sent me for a TB test. Completely blind to anything but the statistically most likely answer, which wasn't really that considering my last TB test was less than a year ago.
I've been off my supplements and steroids for well over a week just so I can take a thyroid test and I feel like shit. If this doesn't give the results the doctor is looking for, I'm going to Mayo so I can see a real physician. And did the doctor bother to order a thyroglobulin antibody test? Of course fucking not. And when do I see her again? 2 months. I am on track to have only seen a physician twice this year with multiple active autoimmune diseases. Damn osteopaths think they know everything and can treat everything. All they really do is sit on their hands and make excuses for not treating you. Like, WTF did you think 'extreme fatigue' meant? Apparently that means I'm fine, lol.
At this point I know more about autoimmune disorders than my hack of a physician ever will and the closest thing I ever had to med school was a year at optometry school.
One thing that has always fascinated me with radioactivity accidents (thankfully not this case because only his hands got hit) is the idea that you could see a flash, know you are a dead man walking, but feel zero pain at first.
Thinking of incidents like the demon core accidents where the nuclear physicists were smart enough to know they had just been killed hundreds of times over but having to wait for the agonizing process of their body catching up to what their minds knew.
If it were me I’d probably seek ways to remove myself painlessly on my own terms immediately, if I were, say, Slotkin.
Truly horrifying fate. I like to think at least some of them wanted to make their sacrifice useful to humanity, and so decided to let things run their course for the sake of scientific discovery
I’ve worked in the electrical distribution industry for 38 years dealing with voltages from 11,000v to 132,000v and have known a couple of engineers who have died similar to this.
An electric arc flash from a fault at EHV voltages can burn at over 22,000 degree C, [the surface of the Sun burns at 5500 degrees C]
But one of the most dangerous things associated with this is the microwave radiation blast that is produced along with it.
If you are caught at close range in one of these Arc flashovers without protective clothing it is a death sentence.
At close range The heat of the flash melts and vaporises metal, clothing and flesh.
You receive 3rd degree burns over your body. But the trouble is that the radiation blast that is produced in effect microwaves and cooks your internal organs.
So you are alive lying in your hospital bed, covered on burns and waiting to die as your internal organs slowly start to fail one by one.
And there is nothing anyone can do about it.
The last I knew one happened in the 1990s, an engineer I knew made an horrendous error, [he accidentally left some electrical test probes plugged to a 33,000volt circuit breaker housing]
He turn the system back on so those exposed probes became live,….
The following day he went into the C/breaker housing to adjust a mechanism, he failed to notice the probes were still in and flashed over against their live terminals.
The most awful thing was that he had a trainee with him and while being loaded into the ambulance he told the trainee that he knew he was going to die.

Wow, gotta say the intro is sick. Also surprises me that this is an incident happened where I was born (Hanoi) but Ive never heard of it, so thank you Kyle for bringing it to my attention.
I know a high school teacher there who does nuclear physics, and he shared that he was actually going to study to become a nuclear scientist and helped the country build its first nuclear power plant, but after incidents like this one and the Chernobyl meltdown, the plan was cancelled due to concerns of safety and risks of meltdown.
Very interesting video overall, looking forward to see whats next.
Never heard of this incident as well, but you can google the professor's name (13:20 - Trần Đức Thiệp). Maybe this is only known in nuclear physicists' circles.
Hearing the serious lack of safety controls and procedures in these accidents is always eye opening to me. I remember doing radiography (a form of non-destructive testing) at my facility once. Everyone but essential personnel were removed, even when the source was in its enclosure. Extra shielding was installed. Extra radiation monitoring was done both before and during movement of the source from enclosure to its testing target (the x-ray source was moved remotely along a track). Signage was placed on all entrances, announcements made over the announcing circuits both before and periodically during the testing. All personnel in the affected area had to wear additional dosimetery with audible alarms (our usual dosimetery was long-term passive devices read once a month) both during the tests and when the source was secured. And our usual dosimetry was read daily even though involved sending it to a separate building, precluding us doing any work while it was being read.
You don't mess around when radiation is involved. Remember TDS - Time, Distance, Shielding? Well you can't do crap about Time and Distance if you have no knowledge at all about when and where the radiation is. And Shielding can be ineffective without *testing* it with radiation measurements to ensure it's doing what you think it's supposed to be doing.
@5:43 "...can do everything by.... hand" nice
I started watching half-life histories a while ago when I was working in a factory. I quit my job and got into a radiation therapy program. Currently I work as a radiation therapist and am halfway through medical dosimetry school. I can't express how much of an impact this channel and your videos have had on me.
Great video as always, keep it up!

That moment of realization must have been truly horrifying, that from a brief 2 minute incident you know your hands are going to slowly die.
Nah, it's just arthritis.
apparently not if it took him a damn week to work out that maybe radiation could be bad for his hands
Yeah true, I chalk it down to a "this is fine" moment. You know its not, but it's more comforting to pretend otherwise.
I was lucky enough to tour Fermilab (4 mile circle) in Batavia, Illinois and the beam just happened to be off when we were there. The tour lead showed us about 5 or 6 newer looking concrete blocks on the exterior wall and explained that the magnets had gotten out of sync and the particle burst out of the ring right through the containment tubes and surrounding magnets and ripped a hole out the original blocks from the wall.
Blew me away there was so much power in a particle soooo small. C is really HUGE.
It is surprising that among the popular comments there is not a single one pointing out the fact of the error at 2:53 and beyond.
The second term contains momentum p=mU, where U is speed. Therefore, even at near-light speed we find that the second term is “Approximately Equal” to the first. But not “Much More” than him.
Glad I found this comment. This bugged me, because in fact, the second term of the equation approaches the value of the first term as the speed approaches that of light. p^2c^2 = (mv)^2c^2 = (mc)^2c^2 = m^2c^2c^2 = m^2c^4
Momentum isn't mv at relativistic speeds - there's an extra dimensionless factor denoted by gamma, which increases dramatically as you get close to light speed.
Gamma = 1/sqrt(1-v^2/c^2)
Hands down, the best particle accelerator story I've heard in a while.
Hands down
@@BonjourGuysBasement😅
for sure 2 thumbs up! well…

So funny I forgot to laugh.
You can go stand in a particle beam at CERN. The north area fixed target beam lines produce pions from the SPS protons. They "turn off the beam" by putting a 2m long concrete block in way making the area safe to access. What the block actually does though is convert the pions into a muon beam. While standing in the beam you feel nothing but it is odd to mentally realize that something is passing through you with the only indication being the flashing lights on your detector electronics. It makes you feel very transparent, like the world isn't really real.

I'm so happy you continued this series, it's by far my favourite of atomic documentaries. You don't waste time with exaggerating details for entertainment, because you understand the story and science behind it are exciting and immersive enough. Wonderful work, Kyle.
Small point: at 2:41 you have 'E = mc^2 + pc' on the screen, but 'E^2 = m^2 c^4 + p^2 c^2' doesn't simplify to that! The real simplification is setting 'p = 0' (which is basically true for non-relativistic speeds) and then E^2 = m^2 c^4 does simplify to E = mc^2
A correction that changes nothing at the end result is completely irrelevant within the context of this kind of video.
You just made me feel dumb.
@@Astraeus.. ok and?
@@Astraeus.. I'm with @kikivoorburg on this one... the fact that it changes nothing to the rest of the video is itself completely irrelevant: the simplifaction is simply incorrect.
Many people watch these videos, and those types of mistakes are remarkable common (I've seen these mistakes on many university-level math exams), despite it being the result of a very basic algebraic formula that everyone has heard of, namely that (a + b)² = a² + 2ab + b², and not just a² + b².
So, I think it is at least necessary to mention this mistake in the comments... to be honest, I absolutely cringed when I saw that simplification made, especially on a Kyle Hill video, where he seems to be very cautious and thorough with the scientific explanation of everything going on.
I would add that the famous E = mc^2 is more correctly written as E_0 = mc^2 (where E_0 means energy at rest).
To go from E^2 = m^2 c^4 + p^2 c^2 to E = m c^2 for p = 0, you would write it as E^2 = m^2 c^4 (1 + p^2 / (m^2 c^2)) and then expand sqrt(1 + x^2) for small values of x as sqrt(1 + x^2) ~= 1 + 1/2 x^2 + ... - which would lead to the classical equation E_k = 1/2 m v^2 for kinetic energy.
We be like that. Need to be held in check.
I used to ride home in the same bus as an electrician working in my university's nucelar power plant. He joked about dropping his screwdriver into "that thing, tried to fish it out, but couldn't reach it, hahaha" he decided to not alert anyone, telling me "there's heaps of stuff down there"...
What university has a nuclear power plant? Seriously, if you're gonna BS people, at least do it right. The only nuclear reactor I've ever heard of at a university was the Chicago Pile back during the early days of the US nuclear project in WWII and it was quickly dismantled after they did their experiments. The only way they were even allowed to do it there was because there was a major war on. These days, fuggheddaboudit. The scary thing is they can work on inventing the quantum bomb with reckless abandon because universities definitely have particle accelerators. If a nuclear bomb only needs 10kg of plutonium, imagine how little mass is required on the quantum level to initiate a catastrophic chain reaction. Surprised there isn't a black hole swallowing us as I type.
@@Lurch-Bot sorry, no time to eead the hole post. The Johannes Gutenberg University in Mainz, Germany, has a nuclear thingy on its campus. It's no secret, google it.

I live in Vietnam, so from what i called, the things with regulations and policies for safety didnt apply much for our people back in the days. Especially back when Vietnam was just gotten out of a huge major war and Economy still try to recover itself. Everything we did was trying our best to getting back on track to live and having a better life, knowing that it would cost us life and many things else.
And for us people, we usually joking about our braveness is on the top list since we were use to cutting bomb to sell scrap and gunpowder also.
So yeah, long story short, it such an honor living in a country like that but also sometimes scary af 😅
I'm Vietnamese too!
I always joke with my friends about the war knowing we were literal cave diggers
I wouldn't call the early '90s 'just getting out of a war'. Your war had been over for almost 2 decades when this happened. The fact is that there is a lax attitude towards safety in your country that is evident still today. All I gotta do is watch a Vietnamese motorcycling video to see that. Enjoy. Ignorance is bliss. The fact is that a communist government will never value human life as much as a capitalist one. You took your cues from the Soviet Union and China. A quick study of history will tell you they thought nothing of murdering people en masse to hold power. Even to this day, Russia is still sending human waves against superior troops. That might work when your back is against the wall but they didn't have to invade Ukraine. Putin is just trying to put the Soviet Union back together and his methods speak volumes to that. He would never fire his nukes at anyone simply because his own people would have him hung, drawn and quartered, assuming anyone was left after the retaliatory strike. And, unlike the old Soviet garbage they're using, our nukes would actually mostly work, instead of mostly being duds. Part of the reason their crap is so unreliable is because a lot of those Soviet subjects engaged in sabotage. And it was cheaply designed in the first place. They definitely didn't expect designs from the '50s to be fighting a war 70 years later.
I will say that it was not America's place to get involved in your civil war. I will also say that the wrong side won and I think the outcome would have been different if there were never any US troops sent to Vietnam. We handed the communists the win just by getting involved. We are still facing the consequences of meddling in China's civil war today, however I am sure a lot of people in Taiwan are glad we did.
But we sealed our own fate by not continuing on to Siberia when we got to Berlin in WWII. The simple fact is that the Soviet Union never should have lasted long enough to have a Cold War, or to corrupt Vietnam with their inhumane ways. You just traded one inhumane dictator (the French) for another. Imperialism comes in many forms and it is most insidious when perpetrated against one's own people. After all, we never tortured any of your people but you did not extend the same courtesy. It is dishonorable. Chances are you have zero idea what really happened at the Hanoi Hilton. You are still subject to anti-American propaganda, even as you pretend to extend diplomatic and trade courtesies. And when I say torture, I don't mean a rap on the head or bright lights, or even waterboarding. I mean torture solely for the purpose of making people suffer as much as possible. Killing them slowly. That's your legacy, next to which carpet bombing empty jungles or even Agent Orange dispersal pales in comparison. We were fighting a difficult war against an insidious enemy. But your side took it out on people who couldn't even run, often because they had been hobbled (deliberately shattering someone's ankles so they can never run again), but mostly because they were captive. Only the lowest excuse for humanity would do such things.
What the US did to Vietnam pales in comparison to what numerous communist regimes have done to their own people. And the Soviets put more people in concentration camps than the Nazis could ever imagine. They treated the Jews as badly; millions died in numerous pogroms.
While Germany and Japan are tales of redemption, Russia is just still holding on to the old ways. They never got what they truly deserved but if they keep fighting with Ukraine, they definitely will. The EU is moving to admit them as a means to stop the war. If Putin persists, beyond a certain point, he will be facing WWIII but this time Russia won't be on the winning side. China is a paper tiger. Doesn't matter about numbers these days. 200 awesome stealth fighters are better than 2000 crappy ones. When you start to impress civilian ferries into military service because you didn't plan for the thing you've been threatening for 70 years, it isn't a threat, it is just sad and pathetic. Like Kim Jong Un and his big missile. Just compensating for an inferiority complex, a common thread among Communist dictators.
What I really don't get is how people could think a government in which they have no say is a good thing. And Vietnam has yet to learn the meaning of freedom.
Do yourself a favor and don't make excuses for the fact your Communist government is lax on safety when you have no leg to stand on; don't even really know history. Especially not on UA-cam.
@@Lurch-Bot tldr btw 😳 and when it comes to safety guidelines nowadays, much more better than before. And tbh, Vietnam just got out of the Trade Embargo by the fking Murica in the late 90s, before that, war in our country actually ended in the 80s again the Chinese and Cambodian. Just saying, if you really are that good and well understanding then come to our “communist country” and live rather than just trash talking 🫣
This is superb. I am a radiation worker and have worked with radiation safety systems. This video would be much better training for the workers than what we get! No one knows the work that goes into protection- the shielding calculations and verification, the interlocks and the procedures.
11:42, I just find it funny that your using URANIUM, to block RADIATION. It's almost like Uranium isn't radioactive anymore or something.
Rebel inc pfp ‼️‼️‼️
Also going over the lack of concern and procedure this sounds like a case of the people involved not knowing what they are doing and not knowing the implications of what they are doing and just simply doing as they are told on the job.
This is what a competency crisis is.
Holy cow it's where I live! Though I never knew we had a particle accelerator, let alone such accident!
You did, when the Cold War made Vietnam important.
What beats me, is that nobody translated the papers from Russian. There were many Vietnamese scientists and other workers in Soviet Union; Vietnam sided with USSR to ward off China. Many must have known Russian at high proficiency.
I also find it hard to believe that at least some of the Vietnamese scientists hadn't studied in USSR
@@EeeEee-bm5gx I think it was less that they couldn't translate or read it, and more that they were in a hurry and being complacent.
@@Salt-ier😂😂😊
@@Salt-ieractual vietnamese pepole in hanoi didnt know what are particle accelerators because they didnt get taught of it alot
I am continually impressed at how you can discuss serious, tragic events with such intelligence and sensitivity.
How the hell does Vietnam have the budget for a particular accelerator and Canada doesn’t?
When you disregard all safety standards it makes things cheaper to build.....
Once upon a time, many years ago, I got to go along on a private tour of the Stanford Linear Accelerator, given by one of the top Physicists to a Physicist who was working on an Accelerator in Australia (who happened to be my father's cousin's husband). At one point they got talking technical, using many words that I couldn't begin to fathom, and then remembered that I was standing there with them, and they apologized to me. And I honestly told them no apology was needed. I didn't understand what they were saying, but I could hear and see their passion and excitement, and it was awesome!
I mention that story to say this: You are a science communicator helping us mere-mortals understand and appreciate the magic of science, but; perhaps one day you could give us an undiluted video of something where you talk-tech were you allow us to be confused by the tech-talk.
I know it's still a cherished moment for me, even though I don't remember any of it. (I think maybe they talked quarks and then got smaller, maybe.)
As always, thank you so very much for the videos.

@@kyledodson2992 While it's true that the younger generations of Vietnameses have familiarized themselves with English to a great degree, in the specific case of this comment section it's more about sampling bias than anything else. People without a sufficient degree of English proficiency wouldn't go out of their way to watch an English video about nuclear physics after all, and having a video about Vietnam would surely draw out the English-capable Vietnameses within the population of viewers.

Hey Kyle! As a (advanced) layperson I really enjoy the way you seem to accurately represent these various nuclear incidents. It's also very cool how you make it clear when you know exactly what you are talking about or otherwise
Here's some interesting incidents I found that I am not aware of any of your videos addressing:
Tokaimura nuclear accident 1999
Kyshtym disaster 1957
Windscale Piles fire 1957
SL-1 nuclear meltdown 1961 (Army)
SL-2 reactor accident 1961 (AEC)
The first one sounds most interesting
The SL 1 and 2 incidents could be exceptionally suitable for a UA-cam format. It gets the curiosity going and I have so many obvious questions
Thanks dude, for everything. All of the science presenters I grew up with really seem to like you and are eager for you to continue their legacy
Actually, he's already covered SL-1. Plainly Difficult did a great video on Windscale, but I would love to see Kyle's take on that story.
Was SL-1 the bizarre Idaho Falls potential love triangle/murder/suicide in the 3-person reactor?
Small correction I have to make. Einstein's equations do not outlaw faster than lightspeed travel. They only say it is impossible to travel precisely at the speed of light. It just is not known if it is theoreticly possible to brake that barrier.
Logically, if you cannot travel at exactly the speed of light, you cannot travel faster than it. Because you have to accelerate through the exact speed of light to reach any speed higher than that - so at some point you will be exactly traveling at the speed of light. Which is impossible.
@vicroc4 What you say is true, but beside the point.
@@Sir_Cactus It's entirely the point. If you can't travel at the speed of light, you can't travel faster than it either. Therefore it is indeed theoretically impossible to break the lightspeed barrier.
Now, there may be ways to bend the rules, or to cheat physics - for example, the Alcubierre metric. But as to actually breaking the speed of light through brute force acceleration? Nah, that's not going to happen.
@@vicroc4 There is still a lot about the universe we do not know and there are lots of open questions. What if something has been travelling faster than c from the very beginning of time.

I will never understand the science behind any of this but the way you describe it is incredible and gives me the slightest glimpse into what everything means!
It's honestly great that you point out that this incident occurred primarily due to human error, not because of the nature of radiation itself. It would be great if more people were aware of these details in regards to these types of incidents.
"... Assuming that if you can't feel something, nothing is happening." Shivers!
