I don’t get how you don’t mind touching alpha and beta . It will for sure damage your DNA and it’s just down to luck nothing worse happens ???

I wish you wouldn't play with that radioactive source

I'm afraid one day he will pay for this

At a certain point these things inevitably become "mathy" and you need to know a bit about maths and statistics so using real numbers in communication is a must so whoever is interested then just has to roll up their sleeves and figure it out. All this nonsensical comparisons that happen in some countries just make things even harder to understand, like "as big as 10 giraffes"... well, in what direction? and which end of the range?

You have a misunderstanding of how thermal radiation works. Any matter which has a temperature above absolute zero emits thermal as electromagnetic waves. At temperatures typical on earth, emission spectrum is primarily in the infrared range. (It's helpful to remember that all electromagnetic energy is composed of massless particles called photons. At the lower energy levels, these are radio waves, and microwaves, infrared radiation, visible light, ultraviolet, x-ray, the highest energy state, gamma rays.) As temperature increases, the wavelength of the emitted photons becomes shorter, until they enter the visible spectrum. Heated metal is an example of this. The radiation is first visible as a dull red, but becomes bright red, orange, yellow, white, and then blue-white, as it passes into the ultraviolet end of the spectrum. Radioactive decay is an unrelated process that involves unstable nuclei emitting a particle to achieve a more stable state.

Fusion is the Future! Unless we Get some Heavy Thinkers!

Never thought it was necessary for me to search informations about a geiger counter and which one to buy. I hope a nuclear war never happens. Greetings from Italy.

As politics keep shutting these places down, the knowledge and desire to operate them will go away and die. It’s already happening. Communities around Nuc plants thrive!

Always take care of RP people. They will feed you on back shifts and save your a$$ when you need them.

The misleading thumbnail is showing magnetism, not radioactivity.

You are asking excellent questions!! and the expert is cautious as to how he answers them hahaha I am a chem eng and a couple of degrees increase in sea temperature is actually considered high, but as long as it's localised then it's fine but it depends on the size of the localised area. Anyone please do correct me if I am wrong in my thinking!

I wonder if someone can answer my question. The 'hood' capture area gives you, say 37k CPM, would that be higher if it can capture the whole plate. Similarly, if you bath in a radioactive hot spring, you will get a whole-body dose that would be a lot higher than if you dip your feet into it. Is the CPM base on surface area? And if so, what is the unit?

If something happens I don't want to live through it

When you say 2000 isn’t a lot, isn’t all to do with luck? It could be enough to just start cancer ?

When I was a kid, my dad had these custom-made goggles, red and purple. Each was made of near-visible light filters. The red one let you see near- infrared. I don't have numbers. The purple one had filters to filter out all visible light except a thin slice near ultraviolet. You had to wear them for like 10 minutes, before you see anything, because there isn't much light that gets through, your eyes have to adjust. But when you do, it's mind-blowing. Dark green pine trees are snow white. The grass, I can't remember, but it might have been white or black. And people looked really weird and icky. They were, effectively, black and white, cuz you could only see a sliver of the spectrum on each end.

want this for airsoft

nu-cle-ar

I'd start with something that can see UV

Well at least is not like the cesium incident in Brazil.

They’re phone lines….

I hope one day I can see that place in person

Thermal is so cool, loved using it in the Abrams as its whats used as the primary gunsight. Way better than NVG's which can't see in full darkness since they rely on ambient light which they amplify (hence why the night sky looks so incredible through them).

I know it is risky with trying new things with content and I like this stuff. We're all science nerds in here (I would imagine for the most part). Great video. Wanna see more of the UFO clips! That sounds very interesting! Keep up the great content Drew!

Are you just risking C when you do those trips? Like is it just a gamble or are the risks actually low?

There are a bunch of mine explorers KZbinrs . I wonder if they even realize the radiation risks they are exposing themselves too??

Montana? You are downwind from Hanford in central Washington State. Also Fukushima has an effect in the Pacific NW.

With those binoculars I can finally find all those hot ladies around me that the ads were telling me about! Thank you

An interesting (if somewhat irresponsible) experiment to do with that radium post would be to use a fan to cool it down, then see if and how long it takes to get back above the ambiant temperatue, and also have a piece of a similar metal, with similar geometery without the radium as a control. Edit: Spelling and grammer.

Pretty cool test, it will be interesting the next time you go underground to see if they detect anything. Either way, thanks for sharing how they work!

So I imagine if you took this expensive equipment to Chernobyl, it should look "foggy", or maybe just slightly lighter image compared to someplace that isn't contaminated. Interesting idea, I didn't think to use thermal imaging to try and detect radiation, but sorta makes sense.

My takeaway from this video: If it's radioactive enough for you to see it with thermal imaging, stay well away from it.

It’s crazy how much the groups of people almost look like they are CGI in a video game and not real

In the early 1980’s I was an Army MP at a small Depot that stored some of the material used in the Manhattan Project

I used to work at a nuke plant back in the mid-90’s. After leaving a radiation area, you had to step into a scanner and actually put 1 arm down into the machine while it scanned 1 side of your body. Then you’d have to turn and scan the other side of your body. If you weren’t contaminated, then you could leave that area. The rad workers that dealt with contamination on people were called “HP’s” (Health Physics). If you couldn’t clear the scanners bcuz you were contaminated, the HP’s would take you to a shower area, throw you a Brillo pad, and watch you shower and scrub your skin. They’d throw you surgical scrubs (shirt and pants that medical professionals dress in) to wear after bcuz they took your clothes to check for contamination. You’d also have to poop and pee into bags so they could check to see if you had internal contamination. It was rare to have someone contaminated, but those that were did not have a fun time and usually had to stay way past clock-out time, until they were no longer contaminated.

Carry a small spray bottle of 50% acetic acid and a UV flashlight. In the dark, spray a suspected uranium ore surface, give it a few minutes and illuminate the area with the UV. Any uranium inclusions will have been converted to uranyl acetate and will fluoresce bright green. Some uranium minerals such as autinite will light up without the acid.

Dude it's Fukashima, it poisoned the pacific and its hitting all of the west coast. Is everyone suffering amnesia?

Tritium is hydrogen, so H₂0, it can be one or both of the hydrogens in water. In practice, tritiums are a tiny, tiny proportion of all the hydrogen atoms around, so what you see in water is THO, a water molecule with one hydrogen-1 and one hydrogen-3. Even if you had some T₂O and dump it into the water, hydrogen atoms swap around and soon enough the tritiums would be in different molecules. Hydrogen is (i think) the only element where the different isotopes have names: protium, deuterium, tritium.

Yeah. Tritium gives off beta radiation, like fission products, but the energy of those betas (electrons) is really weak. Beta radiation only goes a certain distance - not an inverse square law thing. The electrons hit atoms (say atoms in air) and each hit takes a certain amount of energy. Then, it's just an electron, kicking around, making static electricity I guess, becoming irrelevant. So an electron from Sr90 has much more energy than one from Tritium (H3). And, so Tritium is only dangerous from consumption - if you get it into your body, then it is RIGHT AT the molecules that it'll destroy. Like an alpha emitter (alphas also have a short range). Great video! I never knew about this!

These are definitely some “cool“ shots, and I don't think I'm the only viewer who has wondert if you can see trugh a woman's t-shirt with this... But it would also be interesting to see what the picture looks like if you film underneath the Chernobil reactor whear the most radioactive matterial is 😁👍

that guy defiantly knows his stuff

this resolution is so nice, as someone who's used to thermals that have approximately a third of the pixels available. However it's a shame those people can't get their department to implement a proper, modern recorder that provides clean footage. Thank you for going the extra mile to capture this externally!

Would be great if you considered investing in a cloud chamber, video and discuss different type sources and the effects of particles traveling through the chamber.

So you returned an item to Amazon turning a new product into used for this one video? Because you tried to use it for something that it's not supposed to do?

10:17 your idea of little isnt the same as the general population :)

$400 dollar cable sounds like a 10x markup exactly

It would be super cool if you could build a gamma camera. Essentially a lead shielded pinhole camera that you exposed the film to light for a brief period. And then have a light blocking but gamma emissive pinhole and areas of the film that are exposed to high gamma make a glowing aura around the radioactive items on the film.
