Polonium-210 ( 210 Po, Po-210, historically radium F) is an isotope of polonium. It undergoes alpha decay to stable 206 Pb with a half-life of 138.376 days (about months), the longest half-life of all naturally occurring polonium isotopes ( 210–218 Po). [1] First identified in 1898, and also marking the discovery of the element polonium, 210 ...

Po-210 is a product of the radioactive decay of uranium-238, which decays to radon-222 and then to polonium. Polonium 210 has a half-life of 138 days. Po-210 emits alpha particles, which carry high amounts of ...
Polonium-210 is a radioactive isotope that occurs in small amounts in nature and can be made in a nuclear reactor. It has limited uses, mainly in static eliminators. Polonium occasionally makes the news because of its use as a poison. Polonium was blamed for the Nov. 23, 2006, death in London of the Russian Alexander Litvinenko.
Apr 16, 2024 · Po-210 decays to a stable isotope of lead (Pb-206) by emitting alpha particles. The largest part of the alpha dose is delivered over the first 100 days following a single administration. Between 50% and 90% of ingested polonium promptly appears in the gastrointestinal (GI) tract.
Polonium-210 has a very high specific activity—activity per unit mass—of about 166 TBq per gram (4,490 curies, Ci, per gram). In other words, it doesn’t take a large physical amount to be very radioactive. Because of the high specific activity and the large associated thermal cross section, according to a human health fact sheet for 210Po ...
