Вставка
- Опубліковано 7 чер 2024
- We're at Sellafield, in the "active" area of its National Nuclear Laboratory. Getting up close to Uranium, Plutonium, Neptunium and Americium. More detailed videos on those elements coming soon.
In this video are Martyn Poliakoff and Steve Liddle from the University of Nottingham, along with Mark Sarsfield and Chris Maher from NNL.

Sooo uh.... what happened to that kid with his arms in the radioactive drum?
"I'm not allowed to tell you where we're going" Description: We're at Sellafield
The decay sequence is:
Uranium-238 to thorium-234 to protactinium-234 to Uranium-234 to thorium-230 to radium-226 to radon-222 to polonium-218 to lead-214 to bismuth-214 to polonium-214 to lead-210 to bismuth-210 to polonium-210 to lead-206 which is its final stable form.
well, he kept his hands in his pockets for about ... 10 seconds :D
i barely passed chemistry in high school, so i admit i'm shocked at how much time i spend watching these totally fascinating periodicvideos! great work folks!
Those are some nice shoes, professor.
1:30 So Brady basically invented "WHAT ARE THOSE?!" like three years ago.
So if Steve, the "radioactive expert" bites you, do you gain the proportional strength of an expert?
Why not discuss the shoes?
At 0:29, I thought "Oh no, don't look at the map, put your hands on the wheel professor! Oh right, this is Britain.
4:03 You said you have to keep your hands in the pockets
This is sooo awesome! I'm getting my Ph.D. in nuclear chemistry :)
Prof. Poliakoff sure is smart.
This has been the highlight of my day. Can't wait for the updated element videos.
Martyn's hair doesn't just happen. Can you please do a video on how he keeps it so damn awesome?
How did I miss this even though I've been subscribed for a year? I love to see The Professor's sense of wonder at everything from balloons in low pressure to the color of Plutonium salts.
If that man was my connection to chemistry in the first place I would be a chemist :P
I am positively surprised to see this renewed focus on nuclear chemistry. Thanks periodic videos!
Fantastic stuff! I love your videos. You make highly complex subjects not only accessible to the average man but you make them fun. You passion for the subject matter is infectious!!!
Thx for posting this, great videos as always!
This video is awesome! One of the best yet!
"it's hard for me to keep my hands in my pocket"
2 seconds later...
0:08 You don't even have to tell us. The title of the video gives it away.
I still can't wait for your new Thorium video. I hope you get to look into LFTR when you do it!
THANKS PROFESSOR
lol awesome video, love the story at the end lol! cant wait for those next elements.
Can't wait for the new videos!
thanks for the tour!
Thank you for enlightening me... again. looking forward to the new Plutonium vid.
Wonderful lab, the colour of plutonium is certainly interesting, good to get rid of that cliché stigma about radioactive elements all being neon green haha.
Wow The Professor was so happy & excited, like he was going to see the NUCLEAR lab! :D Amazing how every new thing you learn and see in chemistry makes you feel happy like a little kid. :)
Can you do a video showing that Plutonium 241 pellet inside a cloud chamber? I bet it would look amazing.
The Professor's hand gestures excites me just as much as the content of chemistry.
Beautiful just beautiful, I would love to see what goes on there.
No, professor's hair undergoes nuclear decay and still emits radioactive particles.
I have recently been thinking about the properties of catalysts and was wondering if you could do a video on how a catalysts specifically functions and how to predict whether or not a certain compound will act as a catalyst in a reaction. Basically, I am curious about whether or not there is a correlation between the properties of a reaction and the properties of the catalyst being used. Please make a video on this.
I love how the professor is always using his hands when speaking
I did some work for BNFL a few years back, with 1 month's notice I still hadn't cleared security to work at Sellafield and did all my work from satellite offices. I had actually stopped working for them without every being cleared to work onsite. How far in advance did you plan that trip?
loved the video thx for the great effort
Comparing radioactivity to Marmite! That just made my day. Now I'm even more keen to try it.
I’d be interested in your thoughts on thorium reactors for disposal of nuclear waste; on your site all you say about thorium is its use in lenses (which I did not know about, thanks for that info!) and nothing about the amazing properties of pebble-bed and LFTR reactors.
Instant like! More vids like this, please!
I also heard that a nuclear reactor is always being cooled down to keep it from meltdown where as a thorium power core needs to be kept hot to keep it from not operating, is that true?
how about an update video on Fukushima?
interesting things going on there for sure...
Interesting video!
What about lern(palladium),boron 11 fusion or even John Bedini's work?There's a certain status quo and it needs 2 change asap
I one visited an uranium enrichment factory in Almelo, Holland. Never been through so much security measures.
What would be the advantage of using a positive pressure glove box? Why not make them all negative pressure if you want to keeps stuff from getting out of the box?
it was a joke. the boy didnt follow the "hands in pockets" rule so they sarcastically put his hands in a drum labeled radioactive waste.
In my opinion thorium reactors are the future
these videos really make me want to be a chemist but im already 2 years deep into an engineering degree lol oh well maybe a science minor?
How do they get material in and out of the negative pressure glove boxes when there is a risk of contamination, either from radiation or biological hazards?
PARTY IN THE GLOVE BOX
You guys should do a video about the 2 new elements :)
"So you have to think of your experiments enormously more careful than..."
Goes back to lab in Nothingham...
Boom!
Awesome!
how and where do they get the raw materials to do this kind of radioactive experiments?
great vids
Yay!!! A new video!!!
is it possible to overlay text with the chemical compounds as you talk about them so we can learn as we are watching? just an idea. :)
Hmmm.... the 'contamination' the Professor mentioned... if it's not possible to scrub the equipment and decontaminate it, wouldn't that severely complicate the chemistry being done? I'm always curious about purity in chemistry... it seems many reactions are quite tolerant to impurities, but I would expect purity to be extremely important in research settings. Do they have to go to pains to track the history of equipment to accurately record all chemicals involved in each experiment?
Is that a .... periodic table tie? :D
do a video on the 2 new elements please
I couldn't do "hands in the pockets" and still talk about things. I admire you, professor.
The steam may be considered visual or sight pollution in some cases. There often are methods employed to prevent the steam condensing at the top and forming visible clouds.
very cool, thank you!
Yellowcake still the bestlooking.
-
Nuclear power still the best. It will break down to lead or smaller eventually, so best to take advantage of it, accelerate the process if necessary, no CO2 clouds.
Why do you shoot interlaced video?
Chemistry is such a fascinating realm in it's own right to be fair but being a scientist is much more than knowing the facts.
To be a scientist, you must question everything and accept nothing. Only by doing things yourself can you really understand everything and performing even basic experiments, it really helps you view the universe in a whole new perspective.
Seeing really is believing :)
That childhood visit to a nuclear facility must explain the professor's eye-catching hair style!
;-)
I want to know how that row ended what sort of procedures did he have to go through
Is there a visitors Centre for anyone to visit there? I have always dreamed of going to a nuclear Power station! I am fascinated by Ionising Radioactivity
How is the glass and gloves acceptable? Don't you need lead or something like that in between you and the objects radiating alpha particles?
I remember visiting the nuclear visitors senter in wales when i was really young. in 2008 i visited chernobyl and pripyat
highly recommended
The professor's mysterious secret shoes...
Finally we see some real plutonium!
the thing that amazed me is that you hadnt seen radioactive stuff before , your a prof shorly you have
This Professor is one of the most sympathetic people i've ever seen. He's what you would call so "cute". I'm male by the way.
what happened to the boy that is what i want to know now did he have to get scrubbed down?
did he get cancer or was it a drum that had not been used yet
So far I've mixed cocktails myself, does that count? ;) I'm going to uni next autumn. To study chemistry, of course.
hes now a respected professor!
What was that big coloured poster thing the Prof. was reading in the car?
Regarding glove-boxes.. why would any glove-box be positive pressure?
They are likely forced to use a certain version of windows that the drivers and the software for the spectrometer work with.
Many industrial applications still run on win 3.11 because the software was designed to run on it.
Awesome! :D
I hope he could be my professor of Chemistry, of Math or any type of natural science!
I was asking myself the same question. The only explaination i can think of is this one: If you have to deal with chemicals that are not dangerous per se, but dirt from the lab would disturb your reaction. Then a positive glove box would be a good way to protect your experiment.
If you have some thing that is radioactive you may wear a : Hazmat Suit, Mask ( One with holes ) and some pair of gloves - You must wear them all times if you see some thing radioactive. Please move any living thing from any non-stored things that are radioactive.
:3
There's a party in my glovebox and you're all invited.
This is more of a Physics question than a Chemistry question, but: can the effects of alpha and beta particles be obtained by simply creating an electric field that accelerates helium nuclei or electrons? For example, by using an ionizer to ionize helium and accelerate the obtained He++ ions, and by using a Lenard tube to fire out electrons.
If it can't be done, why? What makes alpha and beta particles different than simple helium nuclei or electrons moving at high speed, except their origin?
hahahaha the professor never fails to crack me up !
I have a question. I would like to know if chemical engineering is a good class to do in college, I really like chemistry, these videos helped me to love the periodic table, but i'm worried because I don't really like math and physics. Help me please ): sorry for the bad english, i'm brazillian.
Good point! I don't think we can solve all of our energy needs that way, but it would be a helpful supplement and could provide a cheaper and cleaner way of generating hydrogen for use as a fuel.
@Zeezjay Though Ubuntu really isn't a good example of an OS with security is it? :p
None of the SELinux Fedora and Redhat distros have. Really, if you care about security one would use BSD/UNIX anyway.
5:36 is that a gamma spectrometer?
why in nottingham laboratory the glove box sucks air out? Isn't it dangerous? It doesn't protect that much, right? Anything that's spilled can go into the laboratory
Am I the only one who thinks this is a young Professor Hubert J Farnsworth (Futurama) ?
Love these videos, chem study is behind me now but I watched these videos out of pure fascination! He should definitely have his own TV show.
Is it true that all radioactive elements, when spent, turn to lead?
It astound me every time i hear about nuclear waste containing a good amount of 239 Pu to be stored and locked away. Im really not into conspiracy things and I have a very mitigated oppinion upon nuclear energy, but let me be really sceptical about good intentions prevail on bad ones...
Dont misunderstand me... Im not Telling doc is a liar, I respect him and love periodic videos. I cant wait to see whats next... Continue your good work ;-)
0:17 no, that didn't give me much of a clue, however the title of the video did pretty clearly :)
