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.

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.

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.

Yes. An alpha particle is just a helium nucleus with very high kinetic energy; just as a beta particle is an electron (or positron) with high kinetic energy. However, the names alpha and beta are only used when the particles get ejected from a nucleus. If a gamma ray hits an electron in an atom, the gamma ray may disappear, and its energy will go into kinetic energy of the electron (the photoelectric effect), which then flys off. This electron is not a beta as it didn't come from the nucleus.

@MarcusfotosDe 11 жыл бұрын

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.

Scientists themselves are no different to anyone else, they simply can think differently to solve problems within the industry they work in such as chemistry, mathematics etc... Thinking differently is the key to evolving, theories become relevant when you think about every little thing not just straight forward points. But also being accepting of everything can help.

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's a common misconception, U238 can definitely sustain fission, with one requirement, that the neutrons remain unmoderated. Such reactors are called "fast" as opposed to "thermal" because the neutrons whizz around at the same speed as they were released when fission occurred. Such reactors allow for the complete use of existing uranium reserves and waste products are minimal thanks to the fast neutrons. If necessary, these reactors can also use Th :) Cheap clean energy for everyone forever!

I agree with you, mannonc, that hydrogen is presently best viewed as a fuel, not an energy source. But I note that chemically the situation isn't so clear cut: turning methane into hydrogen could ideally take a little less then 15% the energy made available by turning the resulting hydrogen into water. The carbon could hopefully be captured as graphite and buried.

Fusion is the bomb! ;) I rather see more work be put into that, though I can't say I know to much on the technical benefits of having one kind of project or the other, though I know the energy released through fusion is much better. Waste isn't exactly the issue at that point. I wonder if fusion could replace fission or are they both useful? My mind set is that one is just more primitive and out dated compared to the other, I'm very option to correction/ explanation though.

It's one of the idea they had. Drilling into the crust and injecting pressurized waste into the mantle. However, they also know there would be a risk of radioactive volcanic eruption. Like a normal volcanic eruption isn't deadly enough, make it spurt radioactive lava and ashes.

Depends on your perspective. If you live on the mainland of a major continent then the UK is pretty small by comparison to that. Here in the US just the State of Texas is 696,241 square kilometers which is ~2.85 times the area of the entire UK and that's just the State I live in. Where I grew up if you wanted to go to the theater you had to drive at least 45 minutes to a bigger town that had one. ;p We didn't consider it a long drive.

Radioactive stuff is't used only for energy and bombs. When they had to shut down the reactor at Chalk River, Ontario, it caused a world-wide crisis, because the reactor accounted for 40% of the world's medical isotopes production. medical isotopes can't be stored at all because they have extremely short half-life, the primary characteristic that make them useful for medicine.

They do, but even the best geiger counters can only tell you if something is radioactive, and not what is causing the radiation. For this the tool of choice is the Scintillation Dectector, which actually determines what element is giving off the radiation. This lets it differentiate for example between the K-40 naturally in your body and some Th-232 you really shouldn't have gotten your hands into!

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?

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?
