  • "OnLy It'S tHe BoOgEyMan"

  • depleted uranium not radioactive ? and they give hime millions of dollars to do researching ? lol crazy world...

  • @darwineur

    He said "essentially non-radioactive", though. From what I've gathered that's about right; it's a very low-activity emitter.

  • haha it just looks like a steel wool in my kitchen

  • you read my mind.... i was just thinking about that....i imagine its yelow :)

  • what does it taste like?

  • Isn't that radioactive and harmful to be around?

  • i tried lifting a rod of uranium at the university of canterbury in new zealand it was holow and i still found it had to lift its bloody heavy!!

  • GOOD video for chemistry lovers... or radioactive fan boys

  • @honsiong So true.  I'm a bit of both I guess.

  • is this a Redox Reaction? reduction of Uranium oxide?

  • @periodicvideos how long did all of this actually take

  • Comment removed

  • How do you deplete the radioactivity from a material, an example being Uranium?

  • @Zdawg2324 A common way is to turn the material (uranium) into a gas, then spin it at ultra-high speed in a centrifuge. The material will stratify by weight, which can then be pumped out from a side of the centrifuge.

    Another method is to use a laser that is tuned to a specific frequency to ionize just that one isotope, then use EM fields to remove the ionized material. That's a much more modern approach than the centrifuge.

  • I would like to see they using a geiger counter to measure the radioactivity, just for curiosity.

  • the only thing bad about watching these videos is the comments... people put these long comments...but im not going to read them so theres no point really...

  • wait, uranium is radioactive, yet he has no visible protection, no rad suit, not lead plateing, noting.....

  • @alexzinger123 Bananas are also radioactive. Everything is a matter of degree. Naturally mined uranium is only slightly radioactive. If it was very radioactive, you wouldn't be able to mine it, because it would have decayed into other things billions of years ago.

  • @alexzinger123 2:55

    Maybe if you actually watched the video...

  • 1:51 pubic hair of Saddam Hussain....watch out...may be radio active....what say Collin Powell.....

  • It's probably not worth THAT much. The element collectors can charge people a premium for it because no one else has it. He'll be buying it from a supplier who's probably one step away from a uranium refinery or plant. There'll certainly be more expensive things he could buy from the Sigma catalogue.

    Acids... I get concentrated sulphuric in HDPE bottles. They can't smash, which is a good thing. Doesn't seem to do much at all to the plastic. HDPE is second only to PTFE.

  • congrats! good luck with your research and i'll be looking forward to more videos

  • Congratulations on the grant! Thank you for the video!

  • Do you know how much this shit is worth?

    The presenter should just run and sell it

  • @ozyasghar That is indeed what most people would do, but first of all, it would be noticed and you would not be able to get away with it like that. Another thing is that most scientists are interested in the chemical properties of elements, so perhaps it would be best to just do what you're meant to do with it.

  • I love uranium :$ it's my favorite element of all :P it's really versatile, colorful.

    Unfortunately I can't buy here in Hungary. (On the other hand this is understandable.)

  • @sebibence02 How is that understandable? I own a bit of thorium and uranium myself, and it's really not that dangerous. As long as you make sure you don't EAT it or do other nasty things with it, you should be safe. That's the problem with most people, they are afraid of radioactivity and sometimes decide to outlaw certain elements like that =/

  • @Prstvlkkrtek For example, i thought that some people would use it to kill someone :P It's heavy metal so the proteins don't like that :P

  • @sebibence02 True, but you could also use mercury (Hg), lead (Pb) or arsenic (As). Those are very toxic as well. Uranium is radioactive which tends to scare people.

  • from the pictures, or short clips, Uranium Compounds really are beautifully coloured, its a shame its Radioactive really, I know it has a fairly long half life but still :(

  • @ST0SM hahahaha.. damn right..

    

  • @ajay120 probably high speed steel or tungsten carbide brazed onto a base metal, the latter being more likely. Also machining uranium is dangerous because the smoke is flammable and quite toxic.

  • Steve why is that oil used to store the uranium turnings?

    and if U is so hard, which metal alloy do we use to lathe it?

    regards ajay

  • @ajay120 Oil is used to protect the uranium from unwanted reactions.

  • So where does the green glow come from? waste?

  • no green glow? 

  • what would happen if you stuck a peice of uranium up your ass and farted in someones face?????

  • yes kabila salling uranium for terroriste.bad presidente

  • What pH is this nitric acid?

  • Interesting, how hard is Uranium compared to, say, Tungsten?

  • @AntiProtonBoy What do you mean by that?

  • @cassiavc Well, as far as I'm aware, Tungsten is one of the hardest metals we know, often utilised in drilling equipment and so forth. Apparently Uranium is also quite hard, and used in things like armour piercing ammunition. Hence I was wondering how the two metals compare.

  • i would like to see mercury and uranium with iodine i have no idea y but want to see what happens

  • Bet you Iran would like this...

  • I got scared as hell at 0:40...

  • I saw a girl here on youtube putting nitric acid on pitchblend, and i has got a silvery color. What would happen if I put nitric acid on thorianite (ThO²)?

  • 1million euros or 1.45 million dollars... no need to rub it in ha ha

  • Now eat it

  • Puberanium.

  • Why don't it react to the oxygen after been treated with nitric acid?

  • The guy at 0:39 is such a stereotype image of what a scientist looks like.

  • 0:40 haha

  • @DaWescBoy mad scientist ftw????

  • as i know that Uranium is a radioactive element. Is it safe to deal with it like this ?

  • @tarqdar its been depleated so its not really that reactive no more

  • Uranium is radioactive, there is no stable istopes of Uranium on earth. Depleted Uranium, is U-238, all the fissible U-235 is removed from the 238 atoms, but its still radioactive. It gives off alpha particles, but is about a million times less radioactive than Radium 226. RA-226 is so radioactive, it creates a blue glow from nitrogen in the area surrounding the Radium being ionized.

  • @forwardbias True.

  • @forwardbias And it can burn the skin as well.

  • @forwardbias thats a bit pedantic though, the half-life of U238 is 4.4 Billion years.

  • @forwardbias yes it is radioactive ... but alpha particles can't even get past a sheet of paper , so the gloves he was wearing were enough ... also they are stopped by a foot of air .. so the cameraman isn't iradiated ... hope this was informative , and also if you got depeleted uranium ... wear gloves and glasses :D

  • @yomyssebyy2 Don't forget a mask. Inhaling or ingesting this stuff will kill you in a VERY slow and painful way. Being irradiated by alpha particles from the inside out can't be a fun way to go. Just ask that Russian who ingested the Polonium-210.

  • @forwardbias NERD

  • @clevrsnowmen but this nurd makes more money than you ever will

  • @forwardbias all natural elements have a stable form, buddy.

  • @darkmaster489 You obviously don't know too much about uranium. Go do some reading.

  • @darkmaster489 THERE are elements that don't have a stable form,please learn about Uranium before you post your false accusations.

  • @forwardbias Thanks! :D

  • oh yeah, can i make a nuke with it?

  • no radiation? 0_o

  • Why do scientists always have that crazy hairdo?

  • nice teeth

  • can you guys do a video about radiation, because i thought that if you even came near uranium you would die of cancer within a week.

  • @TheLiberalSoup Nope. However, if you are working with a kilo of cesium 137 or strontium 90, you can kiss your ass good bye. Compare the half-lives with U238 and you'll see.

  • How does one deplete uranium?

  • @ShortGuy1792 u remove what makes it radioactive or something

  • @lemonsodumb I know that much. What I was wondering was what the process was to deplete it.

  • ummmm sir this is youtube....not nudetube plz put some clothes on that uranium hahaha

  • jeasus h crist put some pants on that uranium dude its naked!

  • Hummm depleted U from a lathe ... must be from a munitions factory.

  • His white hair like naked uranium ! lol ..... hehe sry ... no offence =) i love science ! =D Thx for sharing the video ~

  • kinda funny in cartoons Uranium is glowing green now i realized its black and not glowing

  • tht wierdo only talks about money get over it thanks steve

  • U-238 decays (via alpha particle emission) slowly: it's half-life is 4.468 billion years. Now, I'm no chemist but if an element has a half-life I thought that was equivalent to saying it's radioactive. It's puzzling to me that the guy in the video seemed to say it's not radioactive...Can anyone clarify this?

  • @verstengenericks

    yeah, exactly - the uranium he is handling is radioactive, same as any other uranium is radioactive; there's no stable isotope of uranium. it's just that the incredibly long half-time of his U-238 vs. the tiny amount he's handling is probably not measurably radioactive, as it's not distinguishable from background radiation... but it still IS radioactive!

  • @verstengenericks it is radioactive just not that much because its depleted and most of the fissle U-235/U-234 has been removed via enriching uranium this channel has A in depth explaination of the process.

  • @verstengenericks he is probably oversimplifying that its not a dangerous radioactive material in its current state

  • U238 is the non-radioactive portion of uranium. All that there is in the video is almost pure U238. U235 is the radioactive component to uranium.

  • @oobermate u238 is radioactive. It doesn't suppor fission. U-235 & U-233 supports fission. But U-238 is RADIOACTIVE !!!!!!

  • Not radioactive ???? Ahah XD

    wtf ??? How it can't be radioactive...it's Uranium !!

  • looks like a dish scrubber

  • Does anybodey know, where i can get depleted uranium for my privat collection? Here in germany its legal to own deplet, but you cant get it anywere -.-

  • I am pretty sure uranium turnings are radioactive. I bought 25 grams of it from VWR and it is radioactive.

  • Naked Uranium is not really radioactive... I have some mineral of U in my bedroom since 4 or 5 years ago and I am still alive :D

  • rawr. naked uranium.

  • Hey mate, i couldn't help but to notice that the HNO3 in a plastic container. Isn't the concentrated HNO3 meant to be stored in glass container?

  • HNO3 is polar molecule isnt it? so its safe to store it in plastic

  • @fugehdehyou could be teflon, Teflon repels just about every acid. It does this because the molecule is full of fluorine which is near impossible to remove with an acid or base.

  • @fugehdehyou

    Could be a chemically treated plastic (something a little stronger?) dunno.

  • @fugehdehyou It's most likely PTFE.

  • @fugehdehyou Clearly an acid-resistant plastic. In many cases, glass is more reactive than plastics.

  • So many noobs. Simple Uranium isn't radioactive lmfao.

  • isnt depleted uranium still toxic to be around and if some of it get airborn like dust ?

  • this was erbium chloride at 2:51 not a uranium compound

  • put some cloths on naked uranium

  • How did the radioaktivity gone away OO? And why it's still Uranium and no t another element .. ?

  • you should read a bit about radioactive decay, and isotopes. Elements come in different varieties, with different numbers of neotrons, if i remember correctly. Its the number of protons that defines the element. Atoms "decay", wich mean that they "loose energy" maybe due to some interaction, or "spontaneously". When decaying, they form other atoms. Depleted uranium consits mainly of uranium 238 (the number is the isotope), the isotope 235 is what is used in reactors.

  • I was wondering if there'll be a video on how to chemically melt the ice on my footpath... then I remembered - I haven't worked at my school all week in sunny Sandown so I doubt anyone has made it to work at the university :-D (to collect ice melting chemical supplies)

  • ZOMG this will be like the hottest video ever hehe geeky voice

  • I thought that Uranium is green

  • Most shows/comics use green to show radioactive materials. thats where most confusion comes from.

  • well some materiels that are radioactive glow green, I just can't remember which ones.

  • Crazy awesome shit!

  • im Experiment with uranium AND its paramagnetic properties .

  • I love your videos! Congratulations on the grant!

  • Awesome

  • We need more of this, please don't turn this channel into mythbusters.

  • Wow, you propably lost huge amounts of money when you dissolved that tiny layer of UOx into that NHO3.

  • Yeah guys thats what I also have heard but this guy said that this uranium which is depleted isnt radio active!

  • Wow. Congrats on the grant, Steve. That's a healthy chunk of change. Good luck with your research!

  • Crap! 1,000,000 euros!!!

  • There's nothing hotter than naked Uranium.

  • @TheFaustianMan Plutoinium, 

  • @TheFaustianMan 1.27 is pubic hair

    not uranium =)

  • Do you use uranium to make nuclear bombs?

  • No one uses Uranium in that manner.

    that is a construct of Hollywood.

    Uranium has far more practical applications then that which are much more frequent then weapons applications.

  • Uranium IS used in nuclear weapons. It and Plutonium are the only fissile materials you can use to make nuclear weapons. Plutonium is made from Uranium.

    It has other uses, of course, like nuclear power. But it used in nuclear weaponry.

  • Sorry, i was not trying to say its not used in nukes at all,

    My point was that it has more practical applications that should come to mind first like power generation and in part things like nuclear medicine.

  • uranium is a useless materiel in my eye, it produces two wastes as a result of fission, which is worse than 1.

    Nuclear fusion using H, and h2 can produce TONS of energy. with one waste. Helium

  • @lollipopbrigade you seem to be very intelligent

  • Not really, I just studied this stuff not to long ago. So the facts still linger around my head

  • You don't fuse H and H2 to make Helium....that just doesn't make sense at all...

    You use 2 Deuterium atoms and fuse them together to make helium......

  • or rather 1 deuterium atom and 1 tritium atom would work best....because deuterium has 1proton and 1 neutron and tritium has 1 proton and 2 neutrons...the fusion would cause 1 neutron to be lost and you are left with 1 helium atom...

    1 helium atom has 2 protons and 2 neutrons at it's nucleus

  • I wasn't Saying you use H and h2 to Make it, I was saying you use H or H2, To make helium, You're an idiot.

    And need to learn what english is.

  • H and H2 aren't the symbols for Deuterium and Tritium. You are the one that is wrong and need to get your notations straight.

    First off Deuterium is 2H

    Second Tritium is 3H

    Get you chemistry right! :)

  • Comment removed

  • Your chemistry*

  • First off, i wasnt saying tritium, i was saying H, and h2. Hydrogen, and deuterium, Are the most common forms of hydrogen found, Therefore the most likley to be used in the fusion process. When in any of my comments did i mention tritium, tritium is also radioactive, hard to handle, expensive. Not practal I only mentioned two forms of Hydrogen H and H2, Mabye you should get your simple reading, and grammar skills correct, "Get you chemistry right!:)"<< fail by georgiafbi

  • First off I corrected my typo you FUCK FACE :)! Second that doesn't work to make helium. You need 2 Neutrons... how the fuck are you going to get 2 neutrons from HYDROGEN AND DEUTERIUM??? PLEASE TELL ME :).

    AGAIN it is the number before the letter if you are going to represent DEUTERIUM :), THEREFORE, it is 2H :).

    Now correct your CHEMISTRY >:D!

  • You're clearly an idiot, One, if you use H, and H2 in a fusion you would have MULTIPLE Atoms of these two filling up space. Although with your idiocy you will still comment on this, You can't physicly get 2 atoms and fuse them, enough to fill a certain ammount of space. For yo to understand the process of a fusion Reactor Research it, I was simply saying They use H And H2 is the process of Fusion Not a single atom of both.

    They use One or the Other Like is aid many time. Learn Nuclear science

  • AND YOUR NOTATIONS FOR H2 are still being misused >:D. Either put D or 2H. H2 is a diatomic molecule. :D You are a pretty good bullshitter >:D. SHOW THE MATH :). If you show me the math for your "ideas" I'll believe. I've taken ODE, PDE, Calc 1-3, linear algebra, and mathematical physics and along with quantum phy, quantum chem, modern phy..

    In a star these fusion reactions happen all the time. You not only GET helium atoms but you also have different elements being born :).

  • Don't try to impress me with Star Nuclear fusion, thats basicly common fact nowadays.. In a early star you start off with Hydrogen and Trace other gases During its equaliberium H is beign turned to He, h+h= he +neutrino's. there's some math for you. Don't denie this Theory, it's in almost every single astronomy book out there. neutrons are basicly just as common as Protons which is why those 2 neutrons come into picuture, Who cares for notations, I am not impressed by the classes you took

  • Did you mean (Deny*)? :D

  • Look up a video on YouTube called "How Fusion Works" the YouTuber is Imecheuk

    They say you need Deuterium and Tritium to create helium during fusion. Isn't this what I stated? Also look up how fusion works on HOWSTUFFWORKS(.)com

    Your notations are misleading. You could make what you are saying more clear if you knew what you were talking about :D.

  • You Must be retarded that is only thing about you, I never denied the fact that you can make helium with Those 2 isotopes. the fact is you cant read, You can't fuse 2 Atoms. Unless you use somthing like the LHC. but enstead they fuse Trillions of atoms in a single container beign fused, since your border-line retraded i will have to explain this in your intelligence level.

    h+h+h+h+h+h+h+h+h+h+h+h+h+h+h+­h+h+h+h+h+h+h+h+h+h+h+h+h+h+h+­h+h+h+h+h+h+h+h+h+h+h+h+h+h+h+­h+h+h+h+h+h+h+h+h+h+h=He(x)

  • Did you mean instead* not "enstead" :D?

    You are so stupid..... H+H+H+H+H +H+H+H+H does not =helium O.O

    You need high temperatures at about 15million degrees celcius or more. You didn't even add the required temperatures needed to over come the Nuclear BINDING ENERGIES in your equation. Again it's (D+T) ^n + (The Energy Equired to break the Nuclear Binding Energies) = (He)^(n/2)+mc^(2).

    D stands for Deuterium

    T stands for Tritium

    He stands for Helium

    n is the exponential amount

  • @georgiafbi Lmao all you got On me is Nothing,

  • E=mc^(2) is Einstein's famous equation used to calculate the energies released after a fusion reaction.

    m is the Nuclear Mass Defect

    C is the speed of light

  • @georgiafbi moron that's the equasion to calculate how much energy you need to travel at the speed of light

  • Now I know you have no idea what you are talking about....(think about what Einstein's Equation Really Means)

    Think about why his work was so important in the developement of the Atomic Bomb! :D

    Lets simplify this equation for you so you can understand.

    Lets isolate the 2 isotopes of Hydrogen needed to fuse into Helium.

    2H Deuterium

    3H Tritium

    Remember your conservation laws :D

    (2H+3H)+E(binding)=He +mc^(2) +Neutron

    And did you mean equation* not "equasion?" >:D

  • Ran out of room also. Since helium is lighter and requires mroe energy to be a plasma, it can not be fused any further Unless in a star,

  • Did you mean more* and not "mroe?"

  • Helium is lighter than what? Hydrogen O.o? Helium isn't lighter than hydrogen....

    Hydrogen is approximately 1amu

    Helium is approximately 4amu

    Amu stands for Atomic Mass Units usually kg/mole

    Wouldn't you say that 4amu >1amu???

    I would think so :D

    STOP bullshitting your way out of this and admit YOU ARE FAIL >:D!

  • @georgiafbi ether way i meant Heavier

  • Did you mean either* and not "ether?"

    >:D

  • H2 is a diatomic Non-polar Covalent molecule thank you very much LoL

  • He he, Steve Lidl

  • they could have used ketchup ...

  • I think that this is very interresting. I´m a german chemist, but I never worked with radioativ metals like Uranium.

  • This is depleted uranium which is not radioactive!

  • Oh :o

    Sorry, my english is not the best

  • Depleted Uranium still has traces of radioactive Uranium235

  • DU IS radioactive!!!! just on a smaller level....

    and the metal itself is toxic let alone the particle radiation

  • In science you tend to forget the practical uses of some of the elements. Uranium is a very hard substance and if I was given a grant to explore the advantages/crystal structures, I would be looking for an even harder substance that could used as a slug, frame, or hard point for a vehicle.

  • as a sign of very hard metal is the black on the surface, (I always called it carbon steel), some cars with several decades with an active systems, electrical, engine, etc, actually gain as hard, or even harder, as uranium... Great vid. this answers an exact question I posted several months ago..I asked what uranium looked like, and the trait that it is heavier metal. thanks.

  • the nitric acid was scarier than the uranium

  • I want to be the protagonist scientist in a million euro project.

  • lol, i would defintily get cancer from exposure to radiation....

  • Imagine making a knife out of that stuff, real strong blade haha

  • Congrats Steve :D

  • LOLZ lks like i was wrong, i hav a stupid thinking since young tat uranium lks green in colour lk some radioactive substance u see on cartoons

  • Was that concentrated HNO3 stored in a plastic container? Or have I mistaken?

  • So about that tray of sandwiches...are you going to finish that? I'm kinda hungry...

  • but what does radioactive uranium look like?

  • @shafty: Just the same. It's just another isotope of the metal.

  • That's what I mean...!

  • Nothing special... it's just a silvery metal

  • It's not just any metal, it's uranium! I wasn't expecting any special shining, but I appreciate the info and all.

  • What do you mean!?!

    I can't tell you more than the truth...

    Almost every uranium isotope is radioactive. If you want to know more about U235: look on wikipedia or whatever!!

    Also a good idea would be to search in books.

    And what do you mean with "It's not just any metal, it's uranium!"

    You're a genius... U IS a metal
