Cameras used on the international space station experience the same phenomenon. Because the gamma photons have such high energy, they can permanently damage camera sensors, and any camera that's been in space for any length of time tends to have permanent grainy artefacts from dead pixels on its sensor.
I was also supposed to have gone visit the Exclusion Zone in April this year but... yeah... I was a child when all this happened and it scared me so much. So, I want to go to confront it in a way
If you check out Rolf-Dieter Klein's channel, the "10 Sievert per Hour Radiation - tested with the RadioactivityCounter App at the Buchler device" video, you see an extreme example of the artifacts caused by gamma radiation hitting the image sensor. And in a lot of footage from Chernobyl at the time of the accident, you see artifacts from the high radiation environment on photographic film, such as it becoming very grainy or darkened/lightened), as well as flashes.
11:10 How to verify the Gamma Ray interference? It's a well-known effect. I know for a fact that those artifacts showed up on old VHS footage taken around Chernobyl as well. And I guess you can say with high certainty that this is from radiation when it shows up only inside the NSC or around other radiation sources. Cameras are known to be affected by other high-energy radiation as well, like air traffic search radars. I once watched a documentary about the 1982 Falklands War. A camera team filmed on the flight deck of one of the British carriers and every two seconds or so the picture got all "snowy" from white artifacts - this was from the search beam of the main radar-set sweeping over the camera.
Thank you for the content Elina. Hoping that by the time the 100 year anniversary roles around we have made more progress into ways to clean this site up.
A former CEO of the utility I work at went through containment on a tour and didn't put on the shoe booties. When leaving containment a particle was detected on one of his super-expensive Italian shoes that had to be temporarily taken away from him.
I saw a documentry about them working for 1 min at a time, it was unbeliveable. They tried wearing as much lead pieces too - so they carried so much wieght too.
The detector you saw on Kyle Hills chest is called the Ecotest terra p + it's a detector that tells you the radiation levels it does not tell you what your accumulated dose is when you get into the Chernobyl exclusion zone they give you those to see the levels there
Any possibility you could do a reaction to the movie Threads? Everyone talks about how scary it is, but it would be interesting to get a scientific reaction.
Elina, In the future if you are able to go please consider a few stops on your journey through Pripyat. 1. Zavodska Street Firehouse (This firehouse not too far from the Yupiter Bldg is where the first engines responding to the fire came from. The flats alongside the firehouse are where Lyudmilla and Vasily Ignatenko along with many other firemen lived. Their living block was attached to the firehouse. Yaniv Rail Station is where Lyudmilla caught the train to Moscow. This walk took her closer to the power plant and she waited at the train station for a few hours before getting a ride to Moscow for Hospital No 6. Would be interested to know if there are radiation readings after the accident at these two locations and the levels. Please be careful and consider a dust mask as during the recent war troops dug holes into the ground allowing these long buried materials to again be caught in the wind. Stay safe.
Throughout October and November I worked in the local powerplant (the Krško Nuclear Power Plant). Due to the obvious high security no one can approach closer than 500m of the facility. That's why scale was never a thing I really knew before I actually stood under the building. I remember coming in for the first time and just staring because I'd never really been close to a 50+m tall building. And when some people climbed on top to clean the cupola they were so tiny...
You can see radiation effecting a camera sensor a lot more on the robot video from inside Fukushima. It's all over the image. There's also videos on youtube putting GoPro cameras or cellphones near high radiation
_Taller than statue of Liberty, with or without her pedestal?_ It's still amazing to know Lady Liberty is from the 19th century. And by early 21st century we could preserve her within climate-controlled indoor Museum.
I´m also in awe of this construction, and the scale of this accident that might just have had a big impact on my childhood, as I was 8 in Norway when it happened. We were in the fallout area, and accepted dose of milk and meat was raised several times after the accident. Nobody I know are affected though, I just feel for the people of Pripyat at the time, and as far away as Belarus, where a lot of the most dangerous fallout would have landed. But I guess nobody at the plant will talk about that part even today? Either way, I would have a lot of questions for these poor guides. Everyone should know the basics of why the accident happened. The cleanup process is another thing, and not often talked about. Some have found out a bit of what happened, but maybe it´s even dangerous for some to look to far into these operations...
Hi Elina! new subscriber here. I always liked nuclear physics. I worked at the University of Buenos Aires for 23 years, mostly in teaching physics labs. You channel is very good!
@@YourFriendlyNuclearPhysicist I'd like to get in touch, maybe chat some time! I'll drop you a line via the form on your website. You do great work :-)
The channel Dive Talk had some reactions to some videos of people diving with totally inadequate equipment in some buildings they claimed to be in the Chernobyl exclusion zone. Maybe that would be interesting for you to have a look at too.
You know it's actually true when you just looking at it from your TV or a picture you get no scale at all but when he said you could put the Roman Colosseum inside there that's big cuz I've been to the Roman coliseum and it's big.
The white dot artifacts from the gamma rays are legitimate. If you get a chance to look at the raw image from Hubble or Webb they have the same artifacts from cosmic rays.
I have no clue about this things so maybe its a stupid question, but if they make the negative pressure in case of hole/damage, why dont the "just" fill the whole arc whit some kind of material, like the construction foam that hardens after use?
Chernobyl ,and Chernobyl.Why no one speak about Fokushima?There 3 reactors blow up there dome and core melted. Now the best thing,All 3 where run on MOX fuel instead of uranium pellets.Elina could you cover this matter, because I can see everyone trying to brush this disaster under a rug.And my thyroid started playing after 2011.
I love the idea that clothes contaminated with radioactivity will be 'thrown away'. Where? The whole problem with nuclear energy is what to do with waste that will be deadly for tens of thousands of years. Where do you dispose of contaminated stuff? Fukushima is still contaminating the oceans we all share with massive radioactivity. At least we know who and what caused the 6th Great Extinction event on Earth as we watch it happen LIVE from within.
Born in the 60's and the Cold War was very present, As ex military I was all over the Pacific and after I retire I want to tour all of Europe to include Berlin and the location of the wall, and hopefully someday Chernobyl
Can you review the footage of Alexandr Kupnyi? The ones where he went inside the actual sarcophagus and took pictures of the Elephant's Foot? The name of the channel is Some Stuff
Other photography have shown the same white gamma particles so it's very likely this is the cause. Super interesting video and surprisingly inspirational.
The pixel glitches are legit :) Basically radiation are charged particles and such things as a camera photosensor is made of information gathering sensors where the light hits it, under that there is the information translation from light to electric signals. And these part of the sensors which the particles can interact, and make them miscalculate or even discharge a charged tiristor or transistor. So yeah a high radiation level could be seen through a camera from the noisyness of it . Even if the light and other settings are great. The white pixel glich could be an other color I think, but due the structure of the sensor, multiple particles should hit the parts inside it next to eachother, or a shorter wavelength to hit them really fast one after the other.
I find it stupid that he mentioned the elephant's foot, since the radiation captured on the camera would not have come from the elephant's foot (only one of many named melted fuel structures.) since the elephant's foot is very far from him right now in the basement of the reactor... the likelihood of him receiving ANY radiation from it is... very slim if even a percent at all.
By the time the confinement dome needs to be decommissioned or requires major rework, we will have fully functional AI worker androids in mass production. The next overhaul of the Chernobyl site will be done with an army of humanoid robots that can handle much more exposure to radiation than any living person can.
Hopefully. But the current computer technology is not very resistant to radiation either, electronics have to be especially 'hardened' for this kind of usage. (Ask NASA about their collection of failed laptops on the ISS …) We still have to figure out way to make that place safer in the future, so better start research now.
I think I have seen a UA-cam clip from a news site, showing that when the Russian army occupied in the Chernobyl area, in the exclusion zone, that the soldiers had actually dug trenches and Fox holes in the soil. Which has actually disturbed some of the radioactive particles that had been contained in the soils. Which meant the troops that made those trenches home probably have been contaminated..
I'm sure it's been mentioned already, didn't see it in the first couple pages, but Kyle's Half Life Histories series has been fascinating and eye opening.
Yeah, yeah Kyle. That was pretty cool. Let's now discuss how amazing it is when extreme intelligence is combined with being super attractive. When you take over the world please remain kind Elina. And very good job on the videos. Thanks
Chernobyl is what the world calls the plant but it was named for V. I. Lenin. I think the Soviet Union was happy to avoid the association with one of their luminaries. Letting the nearby town be the name history remembers.
Wasn't there another nuclear disaster almost as severe, if not even worse than Chernobyl, that occurred inside the Soviet Union in the 1950s, which seems to have been completely forgotten?
Yes, 20uSv/h is a very low dose rate. It equates to 2mR/h in REM units. Per U.S. federal regulations, the dose rate must be above 5 mR/h before it would even be posted as a "Radiation Area" for nuclear plant workers. Limits for the public are lower still. Also, it seems disingenuous to say "as they blow past the safe limits they set for themselves outside." A nuclear plant worker will always place whatever they were working on in a safe state, and then immediately exit the area if their dosimeter alarms. So his statement makes it seem like someone in a nuclear plant might just ignore what their dosimeter says and keeps on working. That is NOT the case.
@@michaelj3971 Well, I would not call it very low, but it is definitely safe for a relatively prolonged time anyway. Provided that the source of this radiation is not mobile and cannot enter the body of course
@@janboreczek3045 It is very low. The amount of exposure you'd get staying in this area for an hour is the same as what every resident of Denver Colorado gets every 20 hours of their life, day after day, forever. It's about the same as what you'd get on a 4 hour airliner flight. In some areas of Iran, the natural background radiation is over twice this level.
12:45 I work on vacuum systems alot. Vapor extraction as well as odor containment. "In the case of a hole". There definitely are holes EVERYWHERE. You can't avoid it. The idea is that your blowers have to have enough power to maintain the design vacuum pressure for the amount of leakage you have. In this case the output of the blowers is going through a filtration system. For my systems it is usually going to a flare or an activated carbon filter. For this its more like a fine dust filter, MUCH more expensive and the more flow you need to maintain vacuum the more expensive it gets. So I'm actually not sure this was the best approach.
It'll at least be highly radioactive for 500 yrs. It won't be like that for 20,000. It should already be half as radioactive as it was when the meltdown occurred.
16:19 lol. He said "political" and immediately she ends the reaction, not mentioning the fact that indeed, nobody seems to be interested in helping Ukraine dealing with this - even though it may affect many other countries if the project goes belly up. Russia even tried to fight inside the site's perimeter. Incredible.
Will they need to build a larger building to slide over this one in 30-50 years...and an even larger one 30-50 years after that, etc. for the next millennium?
Regarding the noise in the video, it's true - you can even cover the lens of your smartphone and by measuring amount of such noise detect relative changes in radiation #theresanappforthat :P
The biggest catastrophe associated with a nuclear power plant. And that's true, but the fate of Fukushima is still unresolved. If all this spills into the sea... We'll see an ecological catastrophe.
I am so relieved the NSC was finished before the war, just imagine the political debacle if it was only partially finished in the middle of this mess. The new safe containment may have never been finished!
Wish you talked more from the perspective of a nuclear physicists. This was just you watching a video and kinda reacting to it. You have a perspective that we don’t get as much on UA-cam. Please lean into it.
@@stargazer7644 It was worse because Fukashima is still dumping radioactivity into the eco system. Only 78 people died in the first 24 hours of the Chernobyl incident while thousands died in the dirst 24 hours of the Fukashima incident, so I don't understand why you imagine Chernobyl was worse.
@@kenibnanak5554 Exactly zero people died in the first 24 hours of the Fukushima nuclear incident. In fact, I believe only one person (possibly) died from the radiation exposure in the 11 years since. The 20,000 people that died in Japan were casualties of the earthquake and tidal wave and had nothing whatsoever to do with the nuclear accident. Fukushima in total didn't dump anywhere near the amount of radioactivity into the environment that Chernobyl did. Almost all of the radiation it did emit outside of the plant itself was into the ocean, and is so diluted it is difficult to detect.
@@stargazer7644 The issue is which disaster was worse. Fukashima wins hands down. Which missing corpse died of what is irrelevant. Noting also Fukashima is still leaching into the groundwater that supplies Tokyo.
@@kenibnanak5554 Are you comparing the earthquake and tsunami in Japan to Chernobyl? That wasn't "Fukushima". That was the Tohoku earthquake and tsunami. The nuclear accident in Fukushima was triggered by the tsunami and killed no one. And it isn't leaking radiation into the groundwater that supplies Tokyo. The Fukushima nuclear reactors sit on the beach 250 feet from the ocean. All the water under them is brackish. And it is 137 miles from Tokyo.
@Elina Charatsidou, Will we ever have portable nuclear reactors so to power small devices and or even hand held devices? I recently read EGP-6 is world's smallest nuclear reactor? Are there any limitations on how smaller they can get say theoretically?
@15:20: This Problem is not solved, not even really contained - the new roof cost over a hundreds of billion USD, the maintainance will cost even more billions for a hundred years, and it will only last one hundred years at best - the reality is: we have no idea how to deal with this problem longterm. This does not show the triumph of science over the desaster, but the opposite: This is what nuclear power can cost people and countries - basically forever. Nuclear power is only cheap, if you let out all it's real longterm costs from the bill (with or without desaster) - to still be paid by generations hundreds of years in the future. This is technocratic hubris, not scientific triumph.
The thing is, although a great deal of the nuclear contamination was removed by the liquidators, decayed and just gone away in Pripyat there are still several radionuclides present, and several hotspots. Not to mention that in the town and in the area nearby, the contamination has been controlled because it has been left alone for decades. When Russian troops came into Ukraine, they stupidly raised soil, digged trenches & defensive positions and messed around the area, as a result several soldiers got radiation poisoning, 30 years after the disaster and years longpast the disaster. Not to mention that they raised several of the radiation levels inside the plant, and in the sorrounding areas. That whole exclusion zone has to be left in peace.
what if the Russian military's current strategy of targeting power infrastructure strayed into seriously targeting a functioning nuclear plant? I know there have been strikes and fighting around a facility, but I don't think they were intended to target the reactor (Zaporizhzhia?). They damaged surrounding transmission equipment, I believe. If a decision was made to launch a focused attack to "destroy" a reactor, what would the effect be if successful? Let's define "destroy" as breaching the containment structure, disabling the cooling system, and directly damaging the fuel rods. Would the reactor behave in a way similar to the Chernobyl reactor? How dangerous could this be?
Chernobyl was mostly because of the hydrogen gas, it ignited which caused a bunch of pressure that blew out the whole reactor. So in theory hitting a modern reactor directly shouldn't be nearly as dangerous.
Kyle Hill's series on nuclear safety and nuclear history has been absolutely amazing, and given his usual slap-stick, humorous approach to science, the somber, serious tone with which he's calmly but deftly handled the realities of it are a HUGE change of character, and exactly what this topic needs. His videos are a wonderful gift to the world as a whole, educating on multiple areas of science in a way that's both real, mathematical, and entertaining which few can achieve. His nuclear series is yet another wonderful gift to the internet community at large! It's so great to hear other professionals in the field saying he's done a good job on this. Science demands we review each other's work to make sure we're consistently accurate, reliable, and didn't miss anything. Thank you Elina for taking up this important, but often thankless job.
Thanks for watching! Let me know how you liked this reaction video and if you’d consider visiting Chernobyl yourself. Be sure to check out Kyle Hill’s full video, the link is in the description. ☢️👩🏽🔬
@Elina Charatsidou Could you talk about the subject of LFTReactors? I've spent many hours on the subject but it would be fun to hear an unbiased but still knowledgable opinion on the subject. For me it seems like the future we missed 60 years ago and really should develop. Similar to how batteries were 10-20 years ago.
The folks who were allowed to only work for seconds or a minute were the "liquidators' who were doing the really crazy stuff such as shoveling the moderator graphic blocks and other radioactive debree from the roof of what was left of the raactor building back into the crater where the reactor core used to be. The folks were using what looks like military NBC protective gear with medical X-ray protective wear plus improvsed extra protection. Human liquidators were being used because available technology did fail due to the massive radiation. Eventually the some machinery to assist the cleanup efforts based on the Soviet Union's Lunokhod lunar exploration robots was being devised by the Lunokhod developers which were recalled from retirement. That worked because the Lunokhod was designed to work in presence of the cosmic radiation on the moon's surface. The construction workers for the sarcophagus were permitted to work well longer than the liquidators. All sorts of improvised radiation shielding was being used for example massive steel plates welded to the cabin of construction machines to make this safer. Yes, the camera sensors indeed do glitch due to gamma radiation. It's a known problem with image sensors in space. Th problem is quire pronounced on some older space imagery or of the elephant foot.
i like that you always make an effort to add on to what video creators talk about in their original pieces. even if your knowledge areas overlap, you're always adding background information, expanding on the point, or reflecting on whether you've encountered an idea before. i think it is the best way to do reaction content :)
11:36 high energy photons triggering the CCD's "pixels" is actually pretty well known. Video from the ISS or other orbital operations using them, you see the same effect (though not as often!) - and cameras that have been up there for a long duration often develop more dead or hot pixels (stuck fully on or fully off) faster than in normal conditions. I think also, you can find some video footage of inspection of the Elephant's Foot by way of a robot. I'm unsure if the camera was digital or not, but if I remember correctly the amount of visible noise in the recording spikes as soon as there is an open line-of-site to the material.
It is very well known. Radiation damage to very sensitive low light astronomical cameras over time is a real problem, even in normal background radiation environments. A cosmic ray nails your camera, and now you have permanent dead pixels or hot pixels.
I really enjoyed this video, and I've been following Kyle Hill for years, so it was fun to see his video here. I hope Kyle Hill himself sees this, I'm sure he would love it. :) The two of you should consider doing a collab on something
Thanks for the review Elina. I hope it shows that I do my homework, and do my best to present an unbiased view of the world's most infamous location.

Hopefully. But the current computer technology is not very resistant to radiation either, electronics have to be especially 'hardened' for this kind of usage.
(Ask NASA about their collection of failed laptops on the ISS …)
We still have to figure out way to make that place safer in the future, so better start research now.
Thanks again!
Biggest problem was design no contentment building over reactor
when they talked about a hole they meant a hole in the original sarcophagus not a hole in the outer shell. the original concrete could collapse.
This was fascinating 😮
Just wondering what the cancer rates for the workers are. I would assume above average even with the precautions?
That's not more radioactive than my underwear after wearing them for an entire week.
I think I have seen a UA-cam clip from a news site, showing that when the Russian army occupied in the Chernobyl area, in the exclusion zone, that the soldiers had actually dug trenches and Fox holes in the soil. Which has actually disturbed some of the radioactive particles that had been contained in the soils. Which meant the troops that made those trenches home probably have been contaminated..
Elina - it sounded like you said trained whales were used to move the structure!!! 😁🤣😅😂
I'm sure it's been mentioned already, didn't see it in the first couple pages, but Kyle's Half Life Histories series has been fascinating and eye opening.
Yeah, yeah Kyle. That was pretty cool. Let's now discuss how amazing it is when extreme intelligence is combined with being super attractive. When you take over the world please remain kind Elina. And very good job on the videos. Thanks
would you do a video on fukushima and how their efforts to help contain that disaster is working or not?
There's no need it's safe now it wasn't a accident anywhere near as bad
Hello . How about a video on Fukushima nuclear power plant accident.?
Elina - are you going to do something about the Fukushima disaster
Chernobyl is what the world calls the plant but it was named for V. I. Lenin. I think the Soviet Union was happy to avoid the association with one of their luminaries. Letting the nearby town be the name history remembers.
Wasn't there another nuclear disaster almost as severe, if not even worse than Chernobyl, that occurred inside the Soviet Union in the 1950s, which seems to have been completely forgotten?
I must say that I've expected the radiation levels there to be kinda more than the 20 uSv/h measured there
Yes, 20uSv/h is a very low dose rate. It equates to 2mR/h in REM units. Per U.S. federal regulations, the dose rate must be above 5 mR/h before it would even be posted as a "Radiation Area" for nuclear plant workers. Limits for the public are lower still. Also, it seems disingenuous to say "as they blow past the safe limits they set for themselves outside." A nuclear plant worker will always place whatever they were working on in a safe state, and then immediately exit the area if their dosimeter alarms. So his statement makes it seem like someone in a nuclear plant might just ignore what their dosimeter says and keeps on working. That is NOT the case.
@@michaelj3971 Well, I would not call it very low, but it is definitely safe for a relatively prolonged time anyway. Provided that the source of this radiation is not mobile and cannot enter the body of course
@@janboreczek3045 It is very low. The amount of exposure you'd get staying in this area for an hour is the same as what every resident of Denver Colorado gets every 20 hours of their life, day after day, forever. It's about the same as what you'd get on a 4 hour airliner flight. In some areas of Iran, the natural background radiation is over twice this level.
12:45 I work on vacuum systems alot. Vapor extraction as well as odor containment. "In the case of a hole". There definitely are holes EVERYWHERE. You can't avoid it. The idea is that your blowers have to have enough power to maintain the design vacuum pressure for the amount of leakage you have. In this case the output of the blowers is going through a filtration system. For my systems it is usually going to a flare or an activated carbon filter. For this its more like a fine dust filter, MUCH more expensive and the more flow you need to maintain vacuum the more expensive it gets. So I'm actually not sure this was the best approach.
What other approach could they have used in a structure this large?
It'll at least be highly radioactive for 500 yrs. It won't be like that for 20,000. It should already be half as radioactive as it was when the meltdown occurred.
He's the Thor of science I love he's content, binge him I dare you your brain will grow!👌
I don't know about anybody else but if my geiger counter went off I'd be out of that building so The flash would be impressed.
Can you make the base audio for the video much louder. I have the volume on 100% on my phone but the video is still too quiet to listen to outside.
I REMBER THAT AS A KID I WAS 6
16:19 lol. He said "political" and immediately she ends the reaction, not mentioning the fact that indeed, nobody seems to be interested in helping Ukraine dealing with this - even though it may affect many other countries if the project goes belly up. Russia even tried to fight inside the site's perimeter. Incredible.
The problem isn't to make it safe. The problem is to keep it safe for the next 20 thousand years. It's going to be very, very expensive.
Will they need to build a larger building to slide over this one in 30-50 years...and an even larger one 30-50 years after that, etc. for the next millennium?
You seem to have missed the bit where they explained this structure was designed for a 100 year life.
@@stargazer7644 Change the numbers and the point is still valid.
@@ghost307 They're disassembling and disposing of the structure inside. The goal is for it to be done by then.
Regarding the noise in the video, it's true - you can even cover the lens of your smartphone and by measuring amount of such noise detect relative changes in radiation #theresanappforthat :P
Us enlightened know that what they are really doing is keeping the wishgranter for themselves.
React to Shiey sneaking into the exclusion zone
I wish I could have gone into the Chernobyl’s Deadliest Area.
Fascinating
The biggest catastrophe associated with a nuclear power plant. And that's true, but the fate of Fukushima is still unresolved. If all this spills into the sea... We'll see an ecological catastrophe.
Nuclear Physicist REACTS to duke nukem from the cartoon captain planet
Came for the chernobyl stuf, stayed for the beautiful lady
I hope you do get chance to go. I'd love to see your view on it
I was thinking you look familiar and just found out we studied physics at the same university the same year. I don't remember knowing you though.
There is a documentary called "The Russian Woodpecker" on how russians did it on purpose.
So probably a stupid question but what is the difference between nuclear engineer and nuclear scientist what are there roles
I am so relieved the NSC was finished before the war, just imagine the political debacle if it was only partially finished in the middle of this mess. The new safe containment may have never been finished!
My best friend calls Kyle, Nerdy Fabio :D
Now let’s talk about Fukushima.
Wish you talked more from the perspective of a nuclear physicists. This was just you watching a video and kinda reacting to it.
You have a perspective that we don’t get as much on UA-cam. Please lean into it.
Can you make atomic boom in backyard...!
I think Fukashima is possibly a worse accident. If I ever visit Tokyo I won't drink water from there.
What are you talking about? Fukashima was nowhere near the level of accident that Chernobyl was.
@@stargazer7644 It was worse because Fukashima is still dumping radioactivity into the eco system. Only 78 people died in the first 24 hours of the Chernobyl incident while thousands died in the dirst 24 hours of the Fukashima incident, so I don't understand why you imagine Chernobyl was worse.
@@kenibnanak5554 Exactly zero people died in the first 24 hours of the Fukushima nuclear incident. In fact, I believe only one person (possibly) died from the radiation exposure in the 11 years since. The 20,000 people that died in Japan were casualties of the earthquake and tidal wave and had nothing whatsoever to do with the nuclear accident. Fukushima in total didn't dump anywhere near the amount of radioactivity into the environment that Chernobyl did. Almost all of the radiation it did emit outside of the plant itself was into the ocean, and is so diluted it is difficult to detect.
@@stargazer7644 The issue is which disaster was worse. Fukashima wins hands down. Which missing corpse died of what is irrelevant. Noting also Fukashima is still leaching into the groundwater that supplies Tokyo.
@@kenibnanak5554 Are you comparing the earthquake and tsunami in Japan to Chernobyl? That wasn't "Fukushima". That was the Tohoku earthquake and tsunami. The nuclear accident in Fukushima was triggered by the tsunami and killed no one. And it isn't leaking radiation into the groundwater that supplies Tokyo. The Fukushima nuclear reactors sit on the beach 250 feet from the ocean. All the water under them is brackish. And it is 137 miles from Tokyo.
Is wearing just that hard hat helmet good enough?
I would have loved to see the elephant foot
her hair is awesome
@Elina Charatsidou, Will we ever have portable nuclear reactors so to power small devices and or even hand held devices? I recently read EGP-6 is world's smallest nuclear reactor? Are there any limitations on how smaller they can get say theoretically?
No.
@15:20: This Problem is not solved, not even really contained - the new roof cost over a hundreds of billion USD, the maintainance will cost even more billions for a hundred years, and it will only last one hundred years at best - the reality is: we have no idea how to deal with this problem longterm.
This does not show the triumph of science over the desaster, but the opposite: This is what nuclear power can cost people and countries - basically forever. Nuclear power is only cheap, if you let out all it's real longterm costs from the bill (with or without desaster) - to still be paid by generations hundreds of years in the future. This is technocratic hubris, not scientific triumph.
NPILF ?
Thoughts?
is Pripyat really not habitable for the next 20 000 years (google) ? that seems wrong to me
The thing is, although a great deal of the nuclear contamination was removed by the liquidators, decayed and just gone away in Pripyat there are still several radionuclides present, and several hotspots. Not to mention that in the town and in the area nearby, the contamination has been controlled because it has been left alone for decades.
When Russian troops came into Ukraine, they stupidly raised soil, digged trenches & defensive positions and messed around the area, as a result several soldiers got radiation poisoning, 30 years after the disaster and years longpast the disaster. Not to mention that they raised several of the radiation levels inside the plant, and in the sorrounding areas. That whole exclusion zone has to be left in peace.
what if the Russian military's current strategy of targeting power infrastructure strayed into seriously targeting a functioning nuclear plant? I know there have been strikes and fighting around a facility, but I don't think they were intended to target the reactor (Zaporizhzhia?). They damaged surrounding transmission equipment, I believe.
If a decision was made to launch a focused attack to "destroy" a reactor, what would the effect be if successful? Let's define "destroy" as breaching the containment structure, disabling the cooling system, and directly damaging the fuel rods. Would the reactor behave in a way similar to the Chernobyl reactor? How dangerous could this be?
Chernobyl was mostly because of the hydrogen gas, it ignited which caused a bunch of pressure that blew out the whole reactor.
So in theory hitting a modern reactor directly shouldn't be nearly as dangerous.
He saw the elephants foot?
I would love to go with you to visit Chernobyl 🙂
Kyle Hill's series on nuclear safety and nuclear history has been absolutely amazing, and given his usual slap-stick, humorous approach to science, the somber, serious tone with which he's calmly but deftly handled the realities of it are a HUGE change of character, and exactly what this topic needs.
His videos are a wonderful gift to the world as a whole, educating on multiple areas of science in a way that's both real, mathematical, and entertaining which few can achieve. His nuclear series is yet another wonderful gift to the internet community at large!
It's so great to hear other professionals in the field saying he's done a good job on this. Science demands we review each other's work to make sure we're consistently accurate, reliable, and didn't miss anything. Thank you Elina for taking up this important, but often thankless job.
Agreed! Kyle’s Demon Core video is the best I have seen on the subject
Thanks for watching! Let me know how you liked this reaction video and if you’d consider visiting Chernobyl yourself.
Be sure to check out Kyle Hill’s full video, the link is in the description. ☢️👩🏽🔬
I would love to visit, but probably, I won't . Love the reaction ❤🤙
Are you here now?
I loved the video Elina.
@Elina Charatsidou
Could you talk about the subject of LFTReactors? I've spent many hours on the subject but it would be fun to hear an unbiased but still knowledgable opinion on the subject.
For me it seems like the future we missed 60 years ago and really should develop. Similar to how batteries were 10-20 years ago.
The folks who were allowed to only work for seconds or a minute were the "liquidators' who were doing the really crazy stuff such as shoveling the moderator graphic blocks and other radioactive debree from the roof of what was left of the raactor building back into the crater where the reactor core used to be. The folks were using what looks like military NBC protective gear with medical X-ray protective wear plus improvsed extra protection.
Human liquidators were being used because available technology did fail due to the massive radiation. Eventually the some machinery to assist the cleanup efforts based on the Soviet Union's Lunokhod lunar exploration robots was being devised by the Lunokhod developers which were recalled from retirement. That worked because the Lunokhod was designed to work in presence of the cosmic radiation on the moon's surface.
The construction workers for the sarcophagus were permitted to work well longer than the liquidators. All sorts of improvised radiation shielding was being used for example massive steel plates welded to the cabin of construction machines to make this safer.
Yes, the camera sensors indeed do glitch due to gamma radiation. It's a known problem with image sensors in space. Th problem is quire pronounced on some older space imagery or of the elephant foot.
i like that you always make an effort to add on to what video creators talk about in their original pieces. even if your knowledge areas overlap, you're always adding background information, expanding on the point, or reflecting on whether you've encountered an idea before. i think it is the best way to do reaction content :)
Thank you for noticing and for your kind words 👩🏽🔬☢️
@@YourFriendlyNuclearPhysicist as most credible people do. Top job! earned a sub
I actually told my dad in january this year (2022) that i wanted to visit Chernobyl this year. Sadly those plans were cancelled shortly after
Are you like me and spent years learning Russian thinking you could use it when you got to Ukraine? 😅
@@jefforymitchell5697 Hey at least that'll open up a few job opportunities
11:36 high energy photons triggering the CCD's "pixels" is actually pretty well known. Video from the ISS or other orbital operations using them, you see the same effect (though not as often!) - and cameras that have been up there for a long duration often develop more dead or hot pixels (stuck fully on or fully off) faster than in normal conditions.
I think also, you can find some video footage of inspection of the Elephant's Foot by way of a robot. I'm unsure if the camera was digital or not, but if I remember correctly the amount of visible noise in the recording spikes as soon as there is an open line-of-site to the material.
It is very well known. Radiation damage to very sensitive low light astronomical cameras over time is a real problem, even in normal background radiation environments. A cosmic ray nails your camera, and now you have permanent dead pixels or hot pixels.
I really enjoyed this video, and I've been following Kyle Hill for years, so it was fun to see his video here. I hope Kyle Hill himself sees this, I'm sure he would love it. :) The two of you should consider doing a collab on something
Glad you enjoyed it! Would love to do a collab in the future 👩🏽🔬☢️
