ภาพรวม
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.

ตัวอย่างในชีวิตประจำวัน
Po-210 is found in trace amounts in tobacco smoke due to phosphate fertilizer-derived lead-210 that decays to polonium.
ความสำคัญทางอุตสาหกรรม
Po-210 is used in static eliminators for photographic film and textile manufacturing. It was also used in early nuclear weapon initiators.
