Right now I'd like to obtain Geiger counters for these teachers -
supposedly civil-defense era counters are available from somewhere

Instead of $20 civil defense counters, there's also this $110 kit (it
even has an alpha window, usable with smoke alarm sources.) I haven't
bought this one myself, I just found it while searching for GM tube
