The professor is truly great, because: - listening to him you really come to believe that you know and understand the ENG language perfectly well - he explains everything so that everybody, incl me, understands everything (imagine if all YT presenters be like him) - you really would wish to be one of his friends.

He still gets things wrong occasionally. Plutonium was discovered/created in late 1940 to early 1941 at the University of California, Berkeley, not in 1914 as the video states.

Something educational is never a waste of time even if u dont get any of it
@@emileponcelet3439 That may be true to the extent one's subconscious can be primed by the experience, but interest aids in retention, and retention aids in understanding. Time is limited by metabolic processes, so it would be wiser to apply one's attention to garnering knowledge of one's interests, if given the choice. So is it possible to 'waste' one's time on 'education'? I say yes, but perhaps with a caveat that one has an 'interest' in the first place. 'Education' is an interesting subject to ponder. Thanks for the thought provocation.

Why did I not pay more attention to chemistry at school?! This is fascinating stuff! Thank you guys
Your high school teacher does not have the credentials
I can't relate i was always a huge chemistry nerd, I actually went to a year of biochemical engineering school before I got burnt out and became a first responder instead
lol, Chemistry is interesting, but I don't like drawing element formations or memorizing the periodic tables, I rather watch this instead😂
when high school teachers do it it's boring.
As a high school teacher, if kids had this exact person talking exactly lile this inside the classroom, they would still fool around about his hair and only the same few would pay attention.
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 :)
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.
+Kerman Guy Or just surround them by several tons of dynamite and enjoy the show.
+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 Oh damn, I ruined it... 88, is 89.
+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

Rolling over in laughter
Just love that “mad scientist” type of hairstyle! It’s epic when a pure genius sports that hairstyle!
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 is dangerous for two reasons: First, because they use it to make bombs..." I agree.
Second reason?
The radioactivity, of course.
Yeah, but usually you don't go around with a piece of plutonium.
Dense and weight have nothing to do with each other

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!
dang, 80mW seems like a lot for a tiny RTG, the massive soviet terrestrial RTGs only made maybe 100W and were hundreds of pounds.

AS a retired lab technician I have the utmost admiration for anyone involved in the level of work, working in a chamber like that is never easy more so when using highly toxic and volatile reagents . great work guys

I love how every single video has comments that say this is guy looks like science
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.

Really don’t know why this video showed up in my feed but now I learned something.
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.
My dad told me a lot of workers who were involved in the making of clocks with glow-in-the-dark numbers died from radiation poisoning.
And a recent study found traces of radionucleatides in the Los Alamos homes.
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.

+MrWisemasterful Epic! :)
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 about Cesium 137 and Strontium 90?
I thought you were a retired joker, smoker, midnight toker?
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...
That guys tie is awesome!!

"The radioactive waste from spent fuel rods consist primarily of cesium-137 and strontium-90, but it may also include plutonium, which can be considered a transuranic waste. The half-lives of these radioactive elements can differ quite extremely." - Wikipedia "Transuranic" (of an element) having a higher atomic number than uranium (92).
