Kewl. I bought one of those CD Geiger counters, a reconditioned and
tested one, almost new in the box, a while back. Loads of fun, but so
far not a lot of radioactivity around to discover. Guess I'll have to
wait until Ahmadinijad does some atmospheric testing.

You can test smoke alarms...


No good for radon, though. Radon emits mostly alpha particles, and the
aluminum shield over the sensing tube stops 'em.

Well, that's no fun....


Ya need the big stuff--the beta particles and gamma rays from nuclear
decay--to register on a CD Geiger counter. Of course by the time you get
a good, solid reading, you've been sufficiently dosed to witness your
hair eventually falling out, cataracts forming in your eyes, and your
teeth departing your gums. Now that's fun.
