Elina Charatsidou does well to explain the complexities of nuclear physics clearly without ever coming across as condescending. I especially appreciate her humor. I leave each video enriched with knowledge ⚛️. Elina is classy, sassy, inquisitive, enthusiastic and just.so… huggable 😊.

I just randomly discovered your channel and am blown away. I think I've watched about half of the videos and I'm really looking forward to the rest. While I think I have a fairly comprehensive understanding of nuclear physics, to see an expert presenting unbiased content to the public that is understandable to the layman is a real treat to the soul. Monday's payday, so I'll at least photon on the ko-fi and in the meantime subscribe and upvote. I'm just not able to express (in english) how much I appreciate what you're doing.

The problem with depleted uranium ammunition for tanks, etc. is that, unlike natural uranium, it isn't buried. It's just sitting there on the ground after the war, and as Elina said, Uranium is not *harmless*. Probably the worst effect is that it can get into groundwater, which normally does not contain natural uranium. That water then goes into irrigation, etc.

To become a nuclear physicist you must have a degree with physics and maths as major subjects, plus post graduate qualifications in physics. Very interesting but very theoretical. Jobs are a bit scarce nowadays, pay good but not great. I suggest you also consider nuclear engineering. More opportunities and also more practical. For that you typically do a standard engineering course (usually mechanical engineering, but can also be chemical or electrical) and then specialise in nuclear applications post graduate. Either way, it is a fascinating and rewarding career, but the preparatory studying is hard work.

Great thank you

How does lead or metal cooling work in a reactor ? Same as salt ? You handle, not so dangerous metal, with far more control and safety, than viruses and bacteria is handled. 👍 Very nice to know you are safe 🤗

The reason depleted uranium (DU) keeps being brought up is that it is used in weapons (like artillery shells with DU rods) However, its use in the artillery shells has nothing to do with radioactivity - it's just a very dense material, making the shell much heavier, and thus able to do more piercing damage on impact at the same velocity It's also used for radiation shielding, actually, much like lead

Density is not all. DU is brittle and flammable. On impact, a DU armor penetrator will fracture in such a way that the projectile becomes sharper. The heat of impact will ignite the uranium dust inside and outside of the armored target. Uranium is chemically toxic in addition to its radioactivity; and it creates more dust than softer metals. Modern Battlefields are generally poisoned zones, but DU is arguably worse than most. Because it is a highly political subject, I wouldn't trust any information on exactly how much worse it is.

Hey thanks alot, newbie to your channel 😎🤘🍻

Nice job explaining about the difference in fuels for nuclear power plants. I handle nuclear accidents so this is very helpful for my work.

Thanks for letting we everyday people to peer into what you do. I hope the work you and your colleagues do bring us closer to a future where energy is plentiful and clean. Emotionally I like the idea of powering our world with wind, solar and other renewable technologies, but I think our complex and chaotic world needs more options to address needs across the whole globe and potentially other planets too.

I do not see a coffee machine in this lab, I could not work there!

Regarding tasting uranium: Apart from its radioactivity, it is also a heavy metal and thus chemically quite toxic. Apparently plutonium is the most toxic heavy metal of them all. Tasting most metals is not a good idea in general.

I knew a bloke who ate a load of uranium and he just got sicker and sicker. Eventually we had to barium. PS the doctors said they couldn’t do anything to helium.

More day in the life vids!

When I first went to work at Hanford in 1991 there was an old-timer there, who was rumored to have been able to tell the difference between uranium and other yellow powders by taste. I don't think he actually did it since the last time I saw him he was 82 years old. It doesn't take very much uranium to give you very dangerous kidney stones.

Isn‘t uranium still really dangerous if depleted due to chemical toxicity?

There is no solution for recycling nuclear fuel, they still are leaving it sealed in barrels and in underground concrete bunkers. Some can be reused again as fuel or in weapons as they are doing it actively. For now every solution for recycling the fuel will contaminate something.

Na, depleted uranium isn’t particularly dangerous 🤗 You are 100% correct that uranium is toxic but it really needs to be in a water soluble form to get into the body and do any real damage that way. The metal, oxides and diurinates are relatively safe as they have low solubilities in water 🤗 Think of it like lead. A chunk of lead metal isn’t really dangerous by itself but lead acetate is real nasty due to being water soluble as it can mix with your sweat then absorb through your skin etc. All that said, I still wouldn’t recommend messing around with it unless you understand the risks! Hope that helps 🤗

Certainly in less than 20 years We can get electric transportation. We have hundreds of years of fossil fuels available.

Next day he took a biscuit from the same pocket and was about to eat it. He said the taste was like copper sulphate, bitter and unpleasant, and spat it out. Later that day he had an attack of diarrhoea. That was more than 20 years ago and he is still in perfect health.

I recall many years ago seeing a graphic, it may have been in my physics book, that showed the penetrating power of the different types of ionising radiation. If I recall correctly alpha particles were shown being mostly stopped by a sheet of paper or the outer layer skin, beta by aluminium foil whilst gamma would get through a thick layer concrete. Is that a fair comparison? Obviously strength of source would presumably be a factor as well, if something stops 99% then a source 100 times as powerful will deliver the same dose. Regarding what uranium tastes like, wouldn’t chemical toxicity be a big factor as well as radiological risk? Heavy metals tend to be really bad for living systems, I recall being told that if you’re ever directly exposed to plutonium, don’t worry about the radiation as the chemical toxicity will kill you long before the radiation does.

So using the definition you provided, what is the difference between depleted Uranium and Uranium 238?

@wwoods66

Жыл бұрын

Uranium-238 is an isotope of uranium; each uranium atom contains 92 protons and however-many neutrons. Depleted uranium is a mix of isotopes which is notably lacking in U-235. Natural uranium (NU) contains 99.3% U-238 and 0.7% U-235 (and a trace of U-234). In the enrichment process you take, say, 1000 kg of NU and sort the atoms into two batches: • One contains 100 kg, including 5 kg of U-235 (5%) -- that's the low-enriched uranium (LEU) that can be used as reactor fuel. • The other contains 900 kg, but only 2 kg of U-235 (0.2%) -- that's the depleted uranium (DU).

Some of its composites are water soluble? those ones would have a taste... when water sits in an aluminum thermos too long, metal is metal.

When it comes to jobs, still need janitors, machinist's and equipment mechanics ,etc I once had to deliver a 146mm impact socket (roughly 5-3/4") to a conventional power station, needed to be there in less than 4 hrs due to 'downtime cost' I would hope the background checks are a lot more stringent at any power plant than getting a job at McDonald's? 😂

8:35 Please correct me if I'm wrong, but aren't Sieverts intended to be used to measure the dose received from gamma radiation only? Considering that sample will be emitting primarily alpha particles, and the device has no way of discerning between particle types nor the energy of each particle, and has a factory calibration for Cs-137 (for converting raw counts > energy based units like Sv), is it not significantly over-estimating the actual external dose rate?

The sievert is used to convert from a measure of energy absorbed, in grays, to a measure of the biological damage done. The conversion factor varies with the type of radiation. For gamma photons, 1 gray --> 1 sievert, but "Thus for example, an absorbed dose of 1 Gy by alpha particles will lead to an equivalent dose of 20 Sv." en.wikipedia.org/wiki/Sievert The Geiger counter _is_ measuring radiation, but if you know what type your source is putting out, you can set it accordingly, to display in µSv/hr (or whatever).

Regarding the issue of 500uSv on the Geiger counter. I have not had a chance to play with Ranger EXP with pancake tube, and dosimetry is not really my area of expertise, so someone needs to enlighten me on this one. Does this device have a software switch that tells the device it is now measuring 4.2MeV alpha particles and should use some alpha specific calibration profile and not the 662keV CS-137 one? If not, then using it in dose rate and acc. dose mode is only good to look for hot spots or getting the general idea of the sample activity, because those calculated uSv numbers will be completely unrealistic. Unless this device has alpha specific calibration profile, it should rather be used in raw CPS/CPM mode. Anyway, even if there is special calibration profile, such dosimetry against alphas seems pointless as we assume external exposition in this kind of measurements and alphas are pretty much harmful only if their source is ingested.

You are completely correct. Most Geiger counters are not able to determine the energy of the particle or photon, only proportional counters can do that. I think that in this case it would be more accurate and interesting to measure the gamma radiation emitted by the sample with a gamma spectrometer, a device that is capable of determining the energy of the received photon. Like you said, the alpha particles are not really relevant for determining the dose rate.

You should definitely think about creating audio books with your voice and general demeanor,it would make for very easy listening and people would genuinely learn something
