    polonium-210 (210po, po-210, historically radium f) is an isotope of polonium. it undergoes alpha decay to stable 206pb with a half-life of 138.376 days, the longest of all naturally occurring polonium isotopes.[1] first identified in 1898, and also marking the discovery of the element polonium, 210po is generated in the decay chain of uranium-238 and radium-226. 210po is a prominent contaminant in the environment, mostly affecting seafood and tobacco. it is also extremely toxic to humans as a result of its intense radioactivity.

Polonium-210 (210Po, Po-210, historically radium F) is an isotope of polonium. It undergoes alpha decay to stable 206Pb with a half-life of 138.376 days, the longest of all naturally occurring polonium isotopes.[1] First identified in 1898, and also marking the discovery of the element polonium, 210Po is generated in the decay chain of uranium-238 and radium-226. 210Po is a prominent contaminant in the environment, mostly affecting seafood and tobacco. It is also extremely toxic to humans as a result of its intense radioactivity.
