wth?

The only activated salt I have worked with was so screaming hot that the tiny vial was in a pig larger then we could carry. We used it as an open source for a decontamination exercise. Due to the short half life similar to technetium 99m generator, contaminated items/rooms could be reused after 10 halflives. We used activated NaCl in a solution of water where we diluted it until we had our concentration and dose rate for the exercise. The water was clear. The reason we used NaCl was due to the medical isotope shortage of 2009, but since we had access to a reactor we used we had the NaCl activated. The short half life was problematic because we had to get the salt irradiated and transported at a particular time so that it would be used before the activity was gone. To increase this time I am sure that the salt was well irradiated. I never saw it in crystal format because it was too hot in terms of its gamma radiation. During dilution we opened the pig and the sample lid with rubber tongs where we then used a pipet to add distilled water as the vial was still in its pig. Big problem when you talked about the solid state battery, the half life is way too short, and the gamma radiation emitted would be extraordinary. The salt you are using has been activated, but is no longer at the higher energy level? Very interesting video. You would not eat any salt that is currently activated.

hello, keep in mind that measure of dose rate at contact with a geiger are always false as the geiger pancake is highly sensitive to beta & alpha and much less to gamma. So the reading will always be higher than reality. A geiger isnt meant to give dose reading at close range but rather the ambiance dose rate. And to have max precision it should be measured on Césium 137 ( if calibrated on Cs137). Still measuring at contact can tell you if an objetc is radioactive or not and if its a "hot" source or not . And also a rough idea how dangerous the sample can be. So the kind of samples you have causes no threat.

Love the little Chornobyl model display, currently working on one myself with a ligh power laminar blue LED wide beam coming from the reactor and a concealed vaporizer. make it a statement model. i collect Radioactive samples and Geiger counters and built a cloud chamber. just fond your channel and im loving it.

love these little displays you make for these samples, but why do you superglue copper and brass wires together, why not just solder it together?

Upload new content please.Your content is great.💯💯

I have a question, in terms of purely looks what ratio would you need to do to get something to look the same, doesn't need to be chemically accurate. I'm planning on making bases for my warhammer models and I was going to get the simulated soil but the import costs since I'm in sodding yorkshire it's like with you it's more than the cost of the actual soil. I assume the main 4 I'll need for the look and texture is the volcanic rock powder, red iron oxide, black iron oxide and white silica sand.

Great channel!! neverything i was looking for. I have a question regarding all of this. If Salt was placed under lets say linen/cloth and if the strongest form of radiation from the sun lets say....lets say 50x our suns radiation. Without the cloth being burned or harmed......can that salt leave an imprint of some sort on the cloth? if not from the salt alone, what if the salt was mixed with water under the cloth, would there be an imprint from that burst of energy? Thank you.

Fresh sap also glows under uv light, i recently trimmed some blue spruce and pine trees in my yard. I also recently bought a uv light. Tonight i was outside messing around with my uv light and shined it on the fresh sap that was dripping from the trees i trimmed. They lit up.

what would be col, if you could dope the solar cells p type doping which is phosphorus with some of that tritium, so wouldn't that work way better.

Put it inside a gas tight container not a plastic bag. Is far more important to contain the radon and avoid getting it into your lungs than the few gamma rays that come from the mantle.

Fascinating and informative. Didn't know I wanted to learn this:) Thank you

Good model dude, but you need another couple of coats of paint on it, and the green on the replicas is more of a nato drab green imho

Are we sure those are amorphous cells? They look polycrystalline to me!

What PIN Diode was it? Each I can find are ICs, and nothing else

Hello sir. I'm trying to make a simple nuclear battery using Sr-90. It'll be like a betavoltaic battery, but sadly I don't have phosphorous nor do I have any solar panels at the moment. And if I wanted that, I could also just put the solar panels outside. Do you perchance have any idea how I could make such thing? I'm new at betavoltaic, and I own a Sr-90 sample from my old soviet union Dosimeter DR-M3. Greetings

Wow great video!! I'm so curious about this now. Do you intend to do more experiments? Do you think the percussive force of the hammer is causing the potato starch to behave in an odd way like ooblek or is 4 or 5% I think you said to small?

X-rays and gamma rays are the same thing - high energy photons The difference is in their origin - x-rays are a product of electron interaction, gamma rays come from nuclear interaction

Use bananas in the drink!

Why would you want to go to Mars if you are a prisoner?😊

keep going this channel is awesome. keep at it

New interesting content that showed up in my feed. Wouldn't be surprised if the video gains a lot of views 👍👍

Tbh my cooking is worse 😂 You couldve bought a normal rectifier tube for dirt cheap on ebay rather than get a tube from united nuclear

I'm going to test space concretes effectiveness against cosmic rays.....only without any Martian soil and without using the same pressure and in a different atmosphere and without any cosmic rays or most of the constituents of them. 👍

I'm surprised they went with something starch-based for the binder. Refractory cement often uses sodium silicate, a.k.a. water glass, and I'd expect that to be easier to make at an outpost and more radiation resistant.

This is highly under appreciated channel. SUB PEOPLE !

Can you try this with a few cubes of concrete with iron rebar reinforcement? I really want to know how iron oxide content in mars-crete affects the substance. The block didn't multiply the radiation per-say, but I wonder if its poor showing was due to Bremsstrahlung from the metal particles. Probably not, but its a line of inquiry all the same.

One more thing you should have done was to let the Mars crete and the moon crete cure in a vacuum chamber to simulate the atmospheric pressures! That is going to make a load of difference on the effects of the curing process, its actually easier than you think to adjust the pressure inside the chamber to be as close to the martian atmosphere as possible , and the moon's for that matter also! Just saying , take care and let me know if you are planning to make a go of it!

Fun experment. Really fun. I love the enthusiasm for in-situ resource building, and do wish there was more going on here on Earth. Fun.. But.. quick question Why would we be bringing any building materials from Earth, ever? Theres a lot of rocks floating around. A lot of rocks with a lot more metals present then easily reached by surface mining Earth. And we already know that Solar Sails and Moth Drives work so the only fuel is getting a small probe to the astroids they can power themselves back by using the sun. All in all it just seems a bit backwards to not use astroids and in-situ materials now, like today for Earth based projects no less in-situ materials and astroids for a future Martian or Lunar base. Its still good to use in-situ materials as free and here is always better then not here and slightly less then free, and Luna is a great place to practice for all sorts of further exploration with its low gravity and close proximity. But. I mean. Seriously why would you question getting materials from Earth at the end?

Fascinating subject thank you. As you had a plethora of LED's in this I'll shut up about them now 😁

Need to add poop to it...

6:33 so that's how you make a Mars bar

They just found Trinitie in Sodom and Gomorrah, from what they just reported.

谢谢！精彩的讲解🎉❤❤❤

属于探测氡的衰变产物来推断它的浓度？如果闪烁晶体探测器上有云母窗是不是就可以测到a射线？

I'm guessing trying to get panels that have efficiend absorption in the emission spectrum of the phosphorus is important for efficiency.

These are soooo cool! Tonic water, either diet or regular, glows under UV because of the quinine.

You are a renaissance man - a person of many talents. Very well done.

Nice job!

I see uranium glass beer steins in your future

Looks like you had quite the party! And it's always interesting, when a channel with a certain theme takes a little detour.

So glad I found your channel! :)

That bolt is a piece of history and you made an excellent model to hold it.

Your explanations are excellent. This is very interesting. It is fascinating that we can now buy a small instrument that identifies the isotopes that increase the background level. This is amazing to me.

Still better than Temu

🤔 so, since rather than heating irradiated salt to restore its lower energy state, it can instead be dissolved in water (requiring no nec addl energy input), presumably, that’s where it would then dump its excess trapped energy, heating the water 🤔 I’m severely curious how much energy we’re storing in stuck orbitals / I have zero frames of reference to even guess but would love to know on a gauge of degrees increase, per unit water, per unit salt …🧐…. HAHA, EUREKA💡!!.. Caloric Table-Salt 😃!🤓😋

How much americium do you need? I've been collecting buttons from old smoke detectors for a while and am now approaching my first microgram. :)

Thinking about air movement on the tube... I remember being in london one summer and noticing the trains pushing huge bubbles of B.O. in front of them... you could tell a train was coming because it suddenly smelled like you were in a giant's armpit.

Now this is apocryphal... but I've heard that if you live in a basement or something, you can fix the airbourne radon with spider plants (chlorophytum) in much the same way that some plants fix nitrogen.

Great demo! Does the app call out possible sources of the original source based on the decay element detection?
