How to safely handle common radioactive elements Uranium 1: Wear protective clothing on every part of your body, extra protection for vital areas. 2: Use a tool for extended grip, as to limit your proximity to uranium. 3: Remember to thoroughly clean all lab equipment and protective clothing after you have finished. Plutonium 1: Consider your life and all you would be throwing away. 2: Do not handle plutonium.
+Eric Wesson As long as it's outside of your body yes. In fact a thicker sheet of paper or just 10cm of air is enough to stop the alpha radiation. But once it gets inside your body it gets messy
+Kerman Guy uranium in its metallic form is an alpha radiator too so if you have it in an ampulla you don,t need all of this but if you store it in a bottle and you want to get it out you should do all of this
There are quite a few (100+) people in the USA fitted with cardiac pacemakers powered by about 2.5Ci of Pu238. This gives off about 80 mW of heat sufficient to power the device for a long time (half-life is 88 years). When the patient eventually dies, the device is recovered and reconditioned for another person who needs one. One man was offered a battery-powered replacement but he refused as it would require minor surgery once a year, and he preferred his plutonium one!
I have to say, I find explosive decaying plutonium barrels far less embarrassing than spilling a country's accumulated amount of plutonium and sawing the table where it fell to retrieve it. I can't stop watching your videos, they are informative, interesting, and entertaining!
what he means is its very embarrassing when the grand children of grand children knowing that their ancestors dont know how to take care their radioactive waste and leaving the next generation with a contiminated planet to live
@@kousueki7024I completely get where you're coming from, and what you're saying, but also every single generation will create new problems for the next to solve, somehow. Until, of course, they can't fix the issue and everyone dies... Then there will be no more problems :D (or D:)
08:40 "Plutonium is a fascinating metal." That's an understatement! What a shame that Pu is so dangerous. Among its strange behaviors is that some of its alloys -- e.g. Pu + rare earths -- partially remelt upon cooling (via inverse peritectic reactions). After further cooling,of course, those alloys become completely solid.
"Plutonium has a really nasty reputation." ... Noooooohhhh! Really?! xD You know he's a real scientist when you see him write upside down at 5:21 ... also at 6:22 he's still running Windows XP. ;)
I borrowed it off of some libyan nationalists. They told me to build em a bomb, and in turn I gave them a shiny bomb casing full of used pinball machine parts!
Proffesor Martyn Poliakoff has a different research focus then Plutonium chemistry. Proffesor Poliakoff researches "green chemistry" or to avoid the word green: environmentally acceptable processes and materials.

Sellafield, Cumbria, UK receives spent fuel rods from all over the world for reprocessing and storage. It's actually a major British industry.

Extremely interesting. Thank you for the post! BTY, I worked in Los Alamos and lived across a small canyon from the original plutonium lab, which was just up the street from the original Tritium Lab. If you're wondering why so many physicists, like Enrico Fermi, died young, this video indirectly gives you the answer.
Oh, certainly. I read the plutonium book referenced early in this video (owned it since before this video was uploaded). It's made quite clear that scientists dealing with radioactive materials were thoroughly cavalier, even though they definitely had a grasp of the hazards. The ones who were careful simply had a higher incidence of cancer later in life. The ones who were not... well, you only have to watch a documentary about the lives of the workers at Chernobyl to understand how things went for them. You don't immediately die but you suffer a manifest degradation of livelihood. Like getting older decades ahead of schedule, with all the attendant symptoms like heart failure. People who undergo chemotherapy can relate.
@@stephenverchinski409 Don't believe everything you read, and make sure you understand it before you spread it around. There was concern that the somewhat elevated levels of americium (Am) found after the Cerro Grande fire (May 2000) might have been related to activities at the Lab. However, it was later shown that the Am found was due to fire detectors (they contain Am) that were burned in the 400 homes that were destroyed.
As a retired expert in Plutonium I can say the information that Plutonium as being man-made is incorrect. It was discovered in southern Africa that a small natural "reactor" made a small amount of plutonium naturally. Pitchblende, a natural mineral that contains Uranium, emits neutrons through the fission process and the neutrons emitted also make trace amounts of plutonium in the mineral so every natural sample that contains uranium can also make small amounts of Plutonium . Therefore Pu, should be listed as a natural element... Steve Miller retired Scientist
what's also incorrect is that the video states that metallic Plutonium is radioactively toxic because it's an alpha emitter. Human skin will block alpha particles quite readily. What's actually the toxin danger is Plutonium oxides and salts, which are similar to but more toxic than other heavy metal oxides and salts, say lead or mercury salts. And even those you don't want to get on your skin, let alone ingest.
@Carpet Hooligan the amount of Pu in pitchblende is very small. Pu does exist in nature but the amounts are extremely small as it's there as a fission product rather than pristine ore deposits. THOSE have long since fissioned away because of the far shorter half life of Pu as compared to Uranium.
@Carpet Hooligan yes and no. the distinction between natural and man made is debated. Some in the scientific community think if some atoms are found on Earth then its natural. Others put a natural abundance limit on natural elements but two natural elements on the Periodic chart are very rare also. In my opinion if its found naturally in any amount it's a natural element...

+ArtisanTony Actually, I like it. Don't know why, but for a scientist, talking about plutonium, almost a mad scientist or someone who is so into his work and experiments that he could care less about his looksHe'd probably be a blast to spend some time with. As long as you're interested in what he does, especially if you could spend time when he's doing experiments.
I spent a few months delivering radioactive material to an underground storage facility in the middle of bfe Utah. I’ve always thought one day I would hear about an “embarrassing” event out there 🤷♂️
I know :p I was just ironizing, my picture is from an anime. And I don't know why it caught my attention when I was reading the comments. Guess I should sleep.
0:32 I'd just like to point out that this "evolved with it = tolerance; manmade = no tolerance" claim is nonsense. We _don't_ really tolerate uranium well because it's still a heavy metal and thus is toxic, like lead. Uranium is still uncommon, and as such we haven't evolved to handle it (thus, it is toxic). If we're talking about radiation levels, well, natural uranium tends not to be highly radioactive (because if it was, it would have decayed away), while plutonium _is_ more radioactive. It's a selection effect and is nothing to do with evolution or whether it's artificial.
I met Glenn Seaborg in his actinide chemistry lad at Lawrence-Berkeley labs in 1995. Dangerous as his lab was, it was nothing like the lab down the hall where bromine pentafluoride was used to extract oxygen from silicates.
Wow, you must be old gentleman. I remember last year when I went to Berkeley, currently they are trying to proof the" theory of island of stability of elements". It's really coll that you seen the actual actinide lab.

So.. Plutonium produces helium gas and may cause radioactive nuclear waste containers to explode after some years of time.. In our country, Finland, there is a company (Posiva) that is intenting to put our accumulated (used fuel) nuclear waste (some 1500 tons today) in copper containers and bury it in bedrock in one randomly selected place close to one of our nuclear powerplants. Any thoughts?
Extremely small trace amounts of plutonium occur in nature in association with uranium deposits, especially those that formed the natural nuclear reactors at Oklo, Gabon. For the first few millennia after those reactors ceased to be active, the concentrations would have been high enough to mine and refine useful amounts of plutonium, but almost all of it has decayed in the 1.7 *billion* years that have elapsed since the Oklo reactors ran down (see Wikipedia entries for Natural Nuclear Fission Reactor and Plutonium, searching for the word "Oklo" on the latter page).
I just realized how terrified we should be of nerds. We laugh at them and pick on them in school. Then they grow up to think of ways to destroy your entire world! I have a whole new respect for nerds now.
Sellafield used to be known by a more infamous name - Windscale. In the late 50s it was the site of the UK's worst nuclear accident when one of the nuclear piles they were using to manufacture fuel for nuclear weapons caught fire. It burned for several days, releasing large amounts of radiation into the outside environment.
Imagine having some of this in your fridge. A friend comes over. "Hey, look I have some plutonium in my fridge isn`t it cool? By the way, it`s radioactive, don`t touch it!" *Friend takes the recipient and sticks his finger inside it because he thinks you are joking" You call 911.
I did part 1 chemistry at Lensfield Rd in 1973. Alfie Maddocks was my director of studies. He told me all about dropping Britain's complete supply of plutonium, of course. Did he ever show you the press cutting? "Atom Scientist defects to Perron"? I met him again in 1993, at a funeral. He was very poorly and in a wheelchair, a double amputee, and wasn't up to recognising old students. Lovely man!
Hes a brilliant scientist I absolutely love him I just cabt remember his name but I give all scientists studying plutonium much credit and respect which im sure yoy can all agree they deserve it!!!
I am a retired Crystal River Nuclear Generation Plant worker. Our plant manager told me he was on a project that fed small amounts of Plutonium to pigs. They wanted to determine how it would effect humans but they couldn't use humans and the closest animals were pigs. Well one day the pigs escaped. The cleanup was a major radiological event at the test facility. There was pig feces and urine all down the halls of the building. He said it wasn't funny at the time but looking back it was hilarious.
I have been interested in the production of nuclear fuels for years. I'm not a militant or anything like that. Just a guy who is an engineering layman with an interest in how things work.
@@bassmith448bassist5 If you're interested in nuclear waste dumps, check out WIPP, the world's third deepest waste repository, in New Mexico. In Albuquerque, we would see nuclear waste containers on trucks as they headed to the site. It's one reason I got out of N.M.

Something tells me, (and this is just a shot in the dark) but these guys aren't your typical college graduates.
They're on different level than us
I think they are what used to be called Alchemists!

The guy with the wild hair said he studied chemistry at Cambridge university certainly not your "typical college"
Occult Master Alchemists. Freemasons mind controlled drones. Anyone want to be 'edumackated'?
@@kentoscocos5238 Completely different level!
I am a electronics tech (I guy that does the work) and worked with PhD and Masters engineers and could barely understand their "level of understanding" and I have a BA and a licensed electrician. Like Tesla
I'm learning more from this channel than I've ever learned from my old school science classes.
free will/discovering it on your own makes a big difference ime
i got an intro to chemistry from my mum's nursing school chemistry book when I was in junior high. had I waited until sophomore year chemistry class I'd have been bored to tears with chemistry.
- chemical engineer
I feel like I just watched a heavy metal cooking show.
David Pring you mean breaking bad
How to serve man.
I'm starting a process engineering job at the Hanford Site in Richland, Washington, US to clean up the plutonium waste from the Manhattan project in may :)
I can watch this scientist talk all day.
A true intelligent man who is doing the work for humanity to progress
Or humanity to assassinate
@Ace Feeley ….so its ok to store the Pu round at your house ?
True that

Can it lead to bad hair?
I think so 😅😂
+ArtisanTony No hair
+ArtisanTony....................... He does NOT have bad hair!
Lol
+ArtisanTony Actually, I like it. Don't know why, but for a scientist, talking about plutonium, almost a mad scientist or someone who is so into his work and experiments that he could care less about his looksHe'd probably be a blast to spend some time with. As long as you're interested in what he does, especially if you could spend time when he's doing experiments.
I spent a few months delivering radioactive material to an underground storage facility in the middle of bfe Utah. I’ve always thought one day I would hear about an “embarrassing” event out there 🤷♂️
I feel educated.

***** hilariously, the picture is not from an anime.
He said that people with anime pictures are weeaboos, not that you have an anime pic. It was just a statement.
Shi .Kazu It was implied via context ;p
I know :p I was just ironizing, my picture is from an anime.
And I don't know why it caught my attention when I was reading the comments. Guess I should sleep.
0:32 I'd just like to point out that this "evolved with it = tolerance; manmade = no tolerance" claim is nonsense. We _don't_ really tolerate uranium well because it's still a heavy metal and thus is toxic, like lead. Uranium is still uncommon, and as such we haven't evolved to handle it (thus, it is toxic).
If we're talking about radiation levels, well, natural uranium tends not to be highly radioactive (because if it was, it would have decayed away), while plutonium _is_ more radioactive. It's a selection effect and is nothing to do with evolution or whether it's artificial.

*pretends to understand all of this*
He was actually explaining it very well.
@@dude-jk2hn He meant that he the viewer is pretending, not the scientist.
I just accidentally blew up a container of plutonium. Boy, is my face red. (from both embarrassment and radiation burns)
I Don't Know Which Is Worse. Your Joke? Or That I Just Replied to a 2 Year Old Comment
And probably because of the radioluminesent plutonium dust......
@@v.567 Don’t know what’s worse, the fact that I just replied to a 2 year old comment or the joke you made?
I met Glenn Seaborg in his actinide chemistry lad at Lawrence-Berkeley labs in 1995. Dangerous as his lab was, it was nothing like the lab down the hall where bromine pentafluoride was used to extract oxygen from silicates.
Wow, you must be old gentleman. I remember last year when I went to Berkeley, currently they are trying to proof the" theory of island of stability of elements". It's really coll that you seen the actual actinide lab.
@@kaustavsengupta8757 Seaborg was the old one. I was in my 30s. I was at Berkeley working on calcium isotope chemistry at the time. It's a great old lab in a ramshackle building, nothing like the grandiose glass and steel temples of science universities build today to accommodate the egos of Higher Faculty.
@@josephskulan750 may I ask in which field you have done your specialized in? Sorry I m still a Junior research fellow (pursing my PhD)and was on Berkeley for an seminar.
@@kaustavsengupta8757 I specialize in stable isotope chemistry of biological systems. I've mostly concentrated on Ca, but did a postdoc on Fe abut 20 years ago,
I know the Soviets tested rocket engines using bromine pentaflouride as an oxidizer 😂
Thank you so much for making all these videos. Your knowledge, dedication and spirit has deserved much of honor and respect. Thank you!
Thank goodness we have such knowledgeable people looking after that for us! The chemistry of the universe is fascinating, thank you for showing your world to us and giving a glimpse of how exchange processes have helped to shape everything we never even have to think about...it's fascinating to put this with how the electron field has been deducted, I only wish I was intelligent enough to do anything other than guess how to rationalise the two together!
The part about the hole in the table was amazing, pretty ingenious imo
I had no idea the periodic table was so sexy. I kinda have a crush on silicon as carbon is just too damn cheap - hangs out with everyone!

It is a real pleasure to watch and hear experts like this explaining their areas of work.
Ah Nottingham .. I did my Ph.D. there, lived in the city (Sneinton) for 5 years.. Some GREAT pubs!
Barber: "How can I help you?"
Scientist: "Gimme dat Einstein, fam."
Barber: "Say no more."
So.. Plutonium produces helium gas and may cause radioactive nuclear waste containers to explode after some years of time.. In our country, Finland, there is a company (Posiva) that is intenting to put our accumulated (used fuel) nuclear waste (some 1500 tons today) in copper containers and bury it in bedrock in one randomly selected place close to one of our nuclear powerplants. Any thoughts?
I really appreciate that the chemist guy was including details about the real chemistry, as opposed to just ambiguous descriptions
There are corners of TH-cam where genuinely intelligent content lurks and this is one of them.
Extremely small trace amounts of plutonium occur in nature in association with uranium deposits, especially those that formed the natural nuclear reactors at Oklo, Gabon. For the first few millennia after those reactors ceased to be active, the concentrations would have been high enough to mine and refine useful amounts of plutonium, but almost all of it has decayed in the 1.7 *billion* years that have elapsed since the Oklo reactors ran down (see Wikipedia entries for Natural Nuclear Fission Reactor and Plutonium, searching for the word "Oklo" on the latter page).
I wonder if there was once even heavier elements there such as americium and even einsteinium and fermium

Not really. And who's the "we" btw?
Well first off, "nerds" don't exist,they're just people who actually applied themselves in school and the workforce.
@@potatoalpacas6114 exactly lol
@Samuel Smith oof
Sellafield used to be known by a more infamous name - Windscale. In the late 50s it was the site of the UK's worst nuclear accident when one of the nuclear piles they were using to manufacture fuel for nuclear weapons caught fire. It burned for several days, releasing large amounts of radiation into the outside environment.
holy crap talk about a stereotypical mad scientist. XD
Imagine having some of this in your fridge.
A friend comes over.
"Hey, look I have some plutonium in my fridge isn`t it cool? By the way, it`s radioactive, don`t touch it!"
*Friend takes the recipient and sticks his finger inside it because he thinks you are joking"
You call 911.
Can I have the link to your profile picture for.....research purposes?
stalfos slayer It`s annoying now, everyone asks me that.
+Bltch Erica you're the one who deliberately uses hentai for their profile picture.
no, there are like 2 others

I did part 1 chemistry at Lensfield Rd in 1973. Alfie Maddocks was my director of studies. He told me all about dropping Britain's complete supply of plutonium, of course. Did he ever show you the press cutting? "Atom Scientist defects to Perron"? I met him again in 1993, at a funeral. He was very poorly and in a wheelchair, a double amputee, and wasn't up to recognising old students. Lovely man!
I like the guy with the puff hair. hes funny
Real dr. Emmet Brown
Despite the video is 11 years old the quality in any aspects is super great
The dude with "the hair" is Professor Poliakoff who teaches at the University of Nottingham

Hes a brilliant scientist I absolutely love him I just cabt remember his name but I give all scientists studying plutonium much credit and respect which im sure yoy can all agree they deserve it!!!
I am a retired Crystal River Nuclear Generation Plant worker. Our plant manager told me he was on a project that fed small amounts of Plutonium to pigs. They wanted to determine how it would effect humans but they couldn't use humans and the closest animals were pigs. Well one day the pigs escaped. The cleanup was a major radiological event at the test facility. There was pig feces and urine all down the halls of the building. He said it wasn't funny at the time but looking back it was hilarious.
Not for the guy who found and ate the pigs...
Who came here just to see plutonium in a sort of container ? *flies away*

If you're interested in nuclear waste dumps, check out WIPP, the world's third deepest waste repository, in New Mexico. In Albuquerque, we would see nuclear waste containers on trucks as they headed to the site. It's one reason I got out of N.M.
