   Much easier than that - run down to the local camping store and buy some gas
lantern mantles. Unless they've changed something in the last five years or so,
they incorperate a reasonable amount of Th-232 which makes geiger counters click
happily away. No need to even take them out of the plastic packaging (in fact,
probably safer if you don't - there's a reason you're supossed to be careful and
wash after changing the mantle in a lantern).

(...) Uranium or thorium ores are easily found in mineralogic collections... very nice radio-sources ;o) Of course precise calibration is another story! See for example (URL) (19 years ago, 30-Jun-05, to lugnet.robotics.rcx)
