Wow - a degree of paranoia to which I have never even aspired. Of course,
here in the northeastern US, background radon levels from cracked granite
are so high that mere fallout and nuke-plant meltdowns are relatively
inconsequntial.

I have a simple one I made as a pre-teen nerd. I occasionally take it out to
show someone that the following really are pretty hot: old luminous-dial
watches, the high-dispersion glass elements in older camera lenses, and red
Fiestaware.

But never tea.
