I also got some in-14s from Ukraine in about 10 days total, so that
shipping path is likely recovered.

I'm happy to report my purchase of VFDs from Kiev, Ukraine arrived in about
2 weeks. So, maybe the delivery process has now recovered.
Only took 1 day thru ISSC New York; in the past that was easily 5-7 days.

Thorium is a good beta source. That's why the SBM-20 works so well.
Mantles contain alpha emitting isotopes, but are a bad example for testing
tubes for alpha sensitivity. Here you can see a comparison of tubes

The last chart shows almost identical counts for the mantle on the SMB-20
I have an old gas lamp mantle. Very active, but apparently not alpha -
interposing a piece of paper (as has been suggested) has no effect at all.

I have a few as well in the original packaging. I find them at flea markets and antique shows. All of the sellers are unaware of their radioactivity. I paid $2 for each. I have also found some old pharmaceutical products such as corrosive sublimate pills ( contain mercuric salts ) which
The source in a US market ionization smoke detector is very small, under 1
uCi and Am-241. The material is plated on a small ~1/4" button and
typically sealed. They are pretty safe and you could most likely eat it
without any issues. However, it is technically illegal to remove the
source and
probably no use to anyone. It's been on eBay a long time now without any takers. It's just a shell and belongs in the garbage.
