Just as an aside for people who are interested...
I have a bunch of scintillators (which are kind of a high-end Geiger counter which operates on a different principle.) I was excited to test a new one I got which was designed for alpha particles and tore into an old smoke detector for the Americium. It is worth note that the shielding around the material is 100% effective, but also not terribly surprising since alpha particles are stopped very easily. The shielding was also really difficult to tear apart. As a matter of fact, I never even finished of the project before packing up and moving, and I never again got around to breaking out my gear and testing things.
so u never ripped out the shielding to melt it into a tin foil hat. WOW i thought that would be your first priority
a side about smoke detectors. it seem many anti-vax done the research and revealed that smoke is not actually carbon, but instead the emanations of ghosts. and for only $1 trillion dollars Tvbcof will sell you a ghost hunter device, a alpha particle detector and he will also throw in his 'science' book of everything he has learned.
a few have a copy of his 'science book' they use it when on stage in comedy bars. so not really worth getting because in a few months everyone will get the joke
I got my first scintillator when the Japanese melted down four reactors (and blew at least one spent fuel pool containing MOX fuel sky high), and the U.S.'s response was to have a new safe dose 10,000 times higher than the old and shut down the Pacific radiation monitors. Obviously I couldn't trust the goobmint to give a straight story, and I didn't trust the crazed 'tin-foil-hat' idjuts either. What's a guy...who has a fairly high salary...to do? Well, I got the gear I needed to find out for myself.
I was in Si Valley at the time. As a matter of fact there actually was no significant problem that bothered me enough to do anything about, even on the Left Coast. It turned into a side hobby and I obtained various other scintillators and various kinds of samples just to fool around with and gain some hands-on experience. Purely scientific interest with a tinge of expectation that if there ever were an incident which posed a threat, I would be more prepared to analyze it for myself since there were ZERO other entities who I could trust to do the work. At least not in short order.
The funny thing is that I had some relatively hot stuff which would send the scaler into an impressive state of hyperactivity. Since I knew something about the actual dangers, it didn't bother me in the slightest. Normies, however, would wet themselves and run screaming from my lab (aka, my living room table.) The same normies who would run to the vaccination center for their experimental gene therapy jab. Why? Well, they are called normies for a reason.
Here's the general grade of stuff I was messing around with:
Excellent quality gear, but outdated. Real analysis can be done, but with more modern gear characterizations are done by computer and it's a fuck of a lot faster and easier (and more expensive.) Anyway, it's kind of a fun hobby.
