It is found in very low concentrations in the environment as a part of the uranium decay chain and can be derived from lead-containing wastes from uranium, vanadium, and radium refining operations - however, not … 2015-07-31 Po-210 is one of 25 radioactive isotopes of polonium – it decays to lead by alpha particle emission, with a half life of 138 days. So the polonium used to kill Litvinenko must have been made 2018-03-06 Polonium-210 entered the modern public’s consciousness in 2006 with the poisoning of Alexander Litvinenko. For someone to be poisoned with 210Po, a large radiation dose would be needed. John Harrison and colleagues estimated Litvinenko ingested about 4 GBq of 210Po, which delivered a dose in the range of 20 gray, Gy, to 100 Gy (Harrison Polonium är ett radioaktivt metalliskt sällsynt grundämne.Polonium är kraftigt alfastrålande och används därför som strålkälla. De flesta poloniumisotoper är kortlivade stadier i sönderfallskedjor för tyngre ämnen. I naturens tre långa sönderfallskedjor återfinns 210 Po, 214 Po och 218 Po i kedjan 238 U-206 Pb, 212 Po och 216 Po i kedjan 232 Th-208 Pb, och 215 Po i kedjan 235 Polonium-210 is a naturally occurring radioactive element that was discovered in 1898 by Marie Curie. It decays to stable lead-206 by emitting one alpha particle, with occasional excitation in the nucleus and emission of 803 keV gamma rays.

Polonium-210 is one of the world's rarest elements, discovered in 1898 by scientists Marie and Pierre Curie and named in honor of her country of origin, Poland.
