Do not repeat the experiments shown in this video!
Hi everyone! In this video I am going to tell you about such a radioactive metal as thorium which has recently been found in most unexpected places.
Along with uranium and bismuth, thorium is one of the three radioactive metals which is quite abundant in the Earth’s crust. Because of having an incredibly long half life of 14.05 billion years, we figured that almost all the thorium present on the Earth had been synthesized as a result of massive explosion of a supernova or a collision of neutron stars long before our Solar system appeared. - Наука та технологія
400 years ago Crude oil was also considered Useless.
Gasoline was considered useless too. It was simply dumped by Rockefeller in the process of making lamp oil, because it was to dangerous for lamps. At the same time people working on combustion engines were looking for something to run their engines. Today it would be considered to dangerous and dirty to be used. I find it funny when people say lithium batteries are dangerous for use I cars. Because a couple have caught on fire. How many cars catch on fire every day? I know my truck burnt up in my driveway and want even in a wrecked.
@@nealramsey4439 yeah but how many combustion cars are out there? Like a couple billions meanwhile not even a million electric cars and they already started to catch fire
Actually thorium can be used as a fuel in special nuclear reactors that take only 100 years to decompose so doesn't create that many nuclear waste but no one wants to develop those reactors
First thing that came to my mind!
@@emilianoramirez5340
Except that's only a half-truth... One being promoted by a couple of pseudoscience conmen.
Thorium has a much longer half-life than Uranium 235... which means that just like Uranium 238 it needs a hot neutron source to initiate criticality... So it needs to be salted with U 235 to kick it in the ass.
Sustaining criticallity requires more than just getting the neutron cascade started though.
As the fuel decays it produces daughter products that absorb neutrons, gradually reducing the output to a level that can no longer sustain criticallity.
Thorium isn't "cleaner."
It runs for only a fraction of the time that uranium fuel can before requiring that the fuel rods be changed.
It leaves you with more rather than less hot spent fuel to store until it's cooled off enough to reprocess.
Reprocessing of both types of fuel is expensive snd dangerous, but with thorium is must be done more frequently.
Thorium itself is safe enough to be around... the spent fuel rods however are just as dangerous as uranium fuel rods.
The people pushing this half-truth tend to pretend there is some sort of conspiracy to hide cheaper/cleaner energy from consumers.
They are the same sort of folks who rant about perpetual motion machines and "free energy" systems they claim are being covered up by "big energy."
So... no. Not in reality.
If they were actually more efficient/cleaner/safer they would be in use.
They do however inspire lots of people to throw money at conmen who promise a lot of BS to their "investors."

@@RadiusNightly What he says is quite incorrect. Ionizing radiation *can* affect you instantaneously... if it is energetic enough. A dose of 5 Gy will be enough to fry your eyeballs, metaphorically speaking. After receiving a full-body dose of that intensity, you'll develop acute radiation sickness within an hour, which will entail vomiting, shitting yourself uncontrollably, seizures, coma, and death.
Likewise, getting exposed to high-energy X-rays will cause visible and painful burns. So yes, radiation can affect you instantly. But for the average person, you have more to worry about from high voltage than ionizing radiation.
@@vainillachocolate5531 Cancer doesn't develop instantly
Thorium is very useful indeed. It's used in TIG welding electrodes because being a beta emitter it starts an arc very easily. Also used as a cold cathode emitter in some electron guns.
It is not to do with being a beta emitter. In fact, it (or rather its daughters) is a rather poor one. The benefit in the electrodes is a metallurgical one. The electrodes last longer and produce a better weld.
@@revcrussell Simply not true. I don't know where that idea comes from but I used to work in research in electron microscopy where these things are studied at University level. Look up thoriated tungsten work function.
(Work function is the voltage needed to 'pull' electrons out of a metal surface)
physics.stackexchange.com/questions/359187/thoriated-tungsten-filaments
@@qwadratix Yes, it has a lower work function. That is a 'metallurgical' property not a nuclear radioactive property. Thorium is not radioactive enough to reduce the energy to start the spark (enough to matter). There are places where this is done but here it doesn't matter. Look up Kr-85 filled vacuum tubes.
@@revcrussell True, Work function is a property of the quantum states of the electronic structure of the bulk metal. As such it's extremely complex and there's no practical calculation I'm aware of that allows you to compute it directly from basic parameters. However. I entertain a (possibly unjustified) conviction that the electrical potential developed by an unstable nucleus is going to influence the bulk property. I shouldn't have stated it as fact. I'll also add that the beta particles emitted will also tend to produce some ionisation in the surrounding air, Also probably a factor.
But at the end of the day, thorium is added for it's ability to initiate an arc, not it's thermal properties. That much is certain
EVERYBODY knows this.
Why do people like you and the others that post the same comment keep repeating it?
"Thorium's is useless" safer nuclear reactors: am I a joke to you?
Sadly they're only a hypothetical rn. India is researching the technology at the moment but they have not yet found a breakthrough that would allow a thorium reactor to work. You can convert thorium to uranium to use in nuclear power plants, but it defeats the safety issue, and is actually far more expensive than just buying uranium.
@@justcallmenoah5743 I thought there was already a good plan for them, I just remember thorium having to be combined with another element(plutonium?) And it doing the same thing a pure uranium reactor does. But when it fails it seperates thorium from the other element and the entire process stops
@@spicylemon9339 not sure what the other dude is talking about, but there are actual designs that work. We just haven't really seen one of those since the sixties.
One thing to get out of your head is "thorium reactor". You can breed uranium with thorium, but the reactor still technically runs on uranium. Breeder reactors just use the nuclear reaction to make more fuel (like by turning thorium into more uranium) as it generates energy. Other fuel cycles exists but the thorium concept is the best known.
Thorium is also not really about safer reactors, at least not directly, though the proposed designs we see all use fourth generation intrisinsically safe designs. You could not use thorium at all and just use uranium directly and it would be as safe.
The Molten Salt Reactor is the most common type of next-gen reactor that is presented to the public, often in the context of presenting the LFTR (Liquid Fluoride Thorium Reactor) concept. These reactors are intrinsically safe, meaning that there is basically physically nothing that can go really wrong with these reactors. No explosions or meltdown is physically possible. There is also no radioactive gases to escape and all of the fuel is trapped inside molten salt. This is true whether you use thorium/uranium or just uranium.
For reference, most of the commercial reactors around the world are second generation. Third gen reactor are not that common since we built few reactors in the last 20-30 years. Fourth gen reactors are still in experimental stage.
While second gen reactors are extremely safe, third gen are insanely safe (due to integral passive safeties) and fourth gen are absolutely safe (due to intrinsic safety design).
I could also talk on and on about fuel cycles and recycling of nuclear waste, but that'll be for another day.
@@N0M4dIC1RST wow I am very greatful for this deeper knowledge of reactors you've shared :D ty!

Check India's Nuclear program, fast breeder reactor IGCAR kalppakam, India. India is one of largest source of thorium.
Dhruv Sharma why do we need to produce energy, when solar energy is left unused? Isn’t energy conversation to meet any need better than energy production and transmission with loss?
Thorium is a metal that is actually underestimated in importance and underutilized, mainly in fission.
Th-232 is not fissile but it is very fertile, and when it takes on that extra neutron it becomes Th-233 for a very short time then BETA decays into Protactinium 233 for 2 weeks then on to U-233.
There are times where it will decay into U-232 which is junk and has a half life of 60 years but there are ways to deal with it.
U-233 as fuel is the best stuff you can get with a fission to capture ratio of 12 (fission) : 1 (Capture) making U-233 50% better at fission that U-235 which is as rare as platinum and is 4x better than Plutonium 239 which is bred from U-238 because U-238 is not fissile but it is fertile.
Also the U-233 fission cycle produces transuranic wastes that are radioactive for 300 years instead of U-235's thousands and U-238 -> PU-239's tens of thousands. It will also produce considerably less waste due to it's considerably better fission ratio.
So yeah, Thorium is not a metal that no one needs, it's exactly the metal we need and need to properly utilize.
finally someone with sense
i bet they just want the Plutonium and that is the only reason they avoid it.
@@theepicslayer7sss101 its gonna have a lot to do with the price of stuff imo. the normal way we do it makes rhem farfar more money. unless forced its unlikely they'll change any time soon
I also feel I need to add that U-232 in its base synthetic form (there are no naturally occurring instances of U-232) is junk as it is not good for fission, HOWEVER it can be bred into the highly fissionable U-233 with a thermal neutron capture and U-232 is fertile.
One of the proposed ideas and can be done with MSR's is the live removal of U-232 and it's chemical separation and subsequent neutron bombardment in a separate fuel chamber via PU-239. This means the current waste products we have and be "burned" in a breeder for U-232 into U-233 while Th-232 is bred into U-233. This makes U-233 a more viable fuel source and since MSR's can actively filter their fuel cycles unlike solid fuel BWR/PWR's they can greatly increase their efficiency and reduce transuranic wastes.
This does not come without its hefty technical challenges but it certainly needs to be fully explored and tested because the positives outweigh the negatives for civil power production.
@@Spartan536 i have to admit my knowledge of Reactors is limited to some Minecraft mods like IC2 and ReactorCraft or Factorio and the Kovarex Research that lets you turn U238 to U235. (in Minecraft IC2 as well)
tho in ReactorCraft, i used Thorium to make power and less waste since in game it produces less when being fission in the Reactor, i just used the Radioactive waste to launch neutrons at the Thorium to make my power... i doubt it is that easy in real life!

@@robinderoos1166 maybe irradiating the rest of the world is a noble cause, from the Chinese perspective of course.
@hawkturkey Depleted uranium is still radioactive and can poison you if it enters your skin or blood. Using it as ammunition is still improper disposal of nuclear waste and littering other countries with it in conquest of resources, isn't much better than China dumping radioactive materials into products.
@hawkturkey DU is used because it's much denser than lead, which increases its penetrative power and it's pyrophoric so, it bursts jnto flames like cerium. Its perfect for armour piercing projectiles but theres a serious downside. DU isn't at all dangerous _radiologically_ but all uranium isotopes chemically unzip DNA. Because uranium is naturally present we do have machanisms to deal with it, unlike plutonium and other synthetic elements but, its far from benign in large concentrations.

For decades Thorium was used as a coating on the hot filament of vauum tubes when heated it will release more free electrons than just plain metal. Also vacuum tubes using a cathode heated by a filament the cathode sleeve will be Thorium coated.
The cloud chamber is impressive because it shows how much energy a single atom has, think of the scale difference between atom and it's trail..plus the speed it shoots out at!!❤️😊
I love this damn channel and it's in depth explanation of facts unlike other science channels on YT which only explain childish scientific facts which a chemistry or physics students s wouldn't give 2 fs about
Thoisoi2: Thorium is Useless!
Terraria Thorium Mod Players: **sad thorium noises**
Mindustry players: I'm 4 parallel universes ahead of you
Thorium MSR for the win!!
8:35 cinematic vibes ✨👌
"no one needs thorium"
Sam O'Nella: you challenge ME?
Love the funny parts especially. Appreciate the info. Thanks.
I believe an alloy used in manufacturing rocket nozzles for large space rockets has thorium in it.
Just to please gods like Zeus.
I recall it as a mix with copper to give strength and resistance to melting while passing heat to fuel flowing through nozzles. Makes the gods happy when their gas is heated :)
I'm a retired Boilermaker, we used to use 2% thoriated tungsten in out TIG torches but, it was found out to be a radioactive isotope so they stopped using in welding.
Everybody who watched the video knows this.
I play Mindustry. And yeah there's one generator structure there named "Thorium Generator" which uses Thorium and cryo fluid as inputs. I never expected that this Thorium really existed.
You must have one of the new HEV suits. That will be very useful.
Thanks, this is exactly what i needed...for my school project...yes...*goes to ebay and orders 10 thorium pens*
0:42 sounds like the TF2 resupply cabinet xD
Nope its from Half Life, actually all valve games has Half Life texture, files, and samples...
@@LazyAndFabulous yea sure, can you tell what sound from Half Life is?
"Thorium,a metal noones needs"
All simply because you can't weaponize Thorium,yes.
In fantasy, thorium is an extremely rare light blue glowing metal. Highly sought after for its unmatched durability and magical qualities.
John E u mean Thorium in wow?
It's not that China is the only one with rare earth minerals, it's the only country that doesn't classify Thorium as a radioactive hazard. So to mine rare earth minerals outside China one incurs the cost of dealing with the unwanted Thorium.
I find this a bit daft when we have people playing on beaches with thorium rich sand and we have natural gas pipped into our homes which contains a fair amount of radon.
India has world's largest Thorium Reserves..
Thorium is not really much of a hazard unless you eat it of breathe it in as it is an Alpha emitter. The journalists that were taken round Chernobyl after the explosion laughed at being given paper suits to wear but in fact that, along with face masks, was complete protection against the alpha emitting nucleotides. Most elements have radioactive isotopes which occur naturally. Carbon 14 is a naturally occurring radioactive isotope found in all organic material which is why it can be used for Carbon dating objects. As a rough guide, for a given mass, the longer the half-life the less dangerous the radiation. In radiation terms Alpha radiation is high energy, ionising but with a very short path length in free air, Beta particles have fairly long path lengths, have a range of energies and are ionising, Gamma radiation does not react with matter very much and can have enormous path lengths. Ionising radiation is the most dangerous to life. A standard Geiger counter will not detect Alpha particles as they do not make it through the window, Beta particles are counted with high efficiency in a Geiger tube and about 2-3% of Gammas are counted as they react only slightly with the gases in the Geiger tube.
but thorium isnt even a rare earth element.
Indeed thorium is not a rare earth element. Problem is to get certain rare earth elements you may also have to mine thorium which has to be treated as radioactive waste. That's an additional cost to miners in certain countries.
The alcohol vapor chamber experiment was fascinating. Could TIG welding cause long term health issues?
Some of the coolest experiment I've seen in your cloud chamber...
