Do you mean beta? Alpha can be stopped with a sheet of paper. I haven't done the direct /paper / metal and distance test yet. I might get to it this weekend. I have a Geiger Muller tube (Sokes) as well as a pancake (Mepa). The latter is said to be more accurate, but I think the Sokes only measures beta / gamma. I think the mepa does Alpha as well, but I gotta look all that up. The russians who put this tech out don't follow up with good documentation sometimes (Mepa - I'm looking at you!).
Oh they still make Thorium mantles. There is Thorium in the ceramic magnetron in your microwave oven. Edit: Wait, I didn't know about thorium lenses. Dang. Also Americium in your smoke detectors.
I have 1 old vintage lens with Thorium inside. Some people say it can also damage the sensor of the camera. Do you think that is possible? And how dangerous do you think it is to still use a lens like this every now and then?
I'm not sure about the sensor. If it is a long lens and it is the front objective lens it would likely be a ways away from the sensor and likely not an issue I would think. The lenses are perfectly safe to own and use.
Thanks. I still have one more to do. I've been taking a break. The exit signs use Tritium, not thorium. Not something you would usually find in your home. They are practical in areas where it would cost a lot to wire in electricity. They will flow nonstop for 10 years. You can also buy tritium watches. They are considered safe.
Smoke detector contain small trace amounts of Americium-241, which is a byproduct of nuclear weapon tests. They only produce Alpha rays, which are rather harmless, and only produce 20mcp/h up close, so they’re pretty shit.
@@wadch2768 they produce limited amounts of gamma as well, pretty easily picked up by a geiger counter. they're really dangerous to take apart which is why it's illegal to do so, as they can contaminate things if it leaks, and contamination is almost undetectable.
I have old thorium mantles, the packaging has a very peculiar warning advising you not to keep them in your pocket 😂
Yikes! Though in fairness mantles are very brittle and putting them in your pocket is probably a bad idea no matter what.

You can actually get small amounts of pure thorium from within a magnetron within a microwave. You're welcome :D
This is a fantastic title for a video series. Don't they use thorium or some other radioactive element for emergency exit signs?

Who puts thorium in their pocket
What about radio active smoke detectors?
I've been on hiatus from videos for a while but absolutely, Americium is on the docket to be made. I need to just make the time do to that video.
