Alpha Decay of Polonium-210

210Po → 206Pb + 4He

Visão geral

Polonium-210 alpha decays to stable lead-206 with a half-life of 138 days. Po-210 emits a 5.3 MeV alpha particle and is one of the most radiotoxic elements known. Microgram quantities are lethal. It was used in the assassination of Alexander Litvinenko in London in 2006.
