Couldn't an old-fashioned smoke-detector be used as a cheap radiation
detector. Since it detects when the emitted alpha-particles are being
absorbed (by smoke), I assume you could put it in a bag, fill it up
with smoke (or something even better at absorbing) and when it stops
beeping, there is a radiation source more powerful than the built-in
alpha source. It would, of course, need calibration (and you might
want to invert when the beep is emitted).

I don't know enough to say if this is really feasible. Just an idea.
