Chris, the half-life of polonium is like 130 days. If you want it to be radioactive enough to do what it did to Litvinenko, then you need it to be fresh out the reactor.
(also, you would need to buy like half a million quid's worth of these brushes, which would probably show up somewhere).
I hope that Charles B is noting that the tables have been turned here with regard to the usual treatment of conspiracy theories. We are the rational ones this time, making the simple assumption that this was a case of state murder. All the rational, level-headed non-conspiracy types are scrambling around for bizarre possibilities about smoke detectors. I have a collection of little sermons about Occam's Razor that have been made to me over the years.
