[QUOTE="Whiskeyman, post: 564723, member: 13556"] There are no stable isotopes of Polonium (Po), and some of the isotopes are [I]really nasty[/I]. Besides, the useful life of such a device would be rather short, due to the short half-life of Po. (Estimates are that it might be useful for up to one-year.) It's been over 30 years since I've had a nuclear physics/engineering course, but this is one of the elements that I still remember studying, and I'd be reluctant to use such a brush that emitted so many alpha particles. (Most industrial anti-static devices today are beta-particle emitter, and the use of Po or other alpha particle charging in industrial anti-static applications has been almost completely stopped.) I can't imagine that you'd be able to purchase any consumer item with Polonium today, but I'm intrigued now and will have to look for them on the net. WM [/QUOTE]
