It undergoes alpha decay to stable 206 Pb with a half-life of 138.376 days, the longest of all naturally occurring polonium isotopes . [1] Polonium-210 is highly radioactive substance and a lethal poison. Polonium is a radioactive chemical element (atomic number 84) that was discovered in 1898 by Marie Curie, who named the element Polonium 210 som är den enda naturligt förekommande isotopen med någorlunda lång halveringstid (138 dygn), kan framställas i grammängder genom neutronbestrålning av vismut 209. Polonium används som strålnings- och jonisationskälla bland annat vid aktiveringsanalys (jmf californium ). 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 Polonium-210 entered the modern public’s consciousness in 2006 with the poisoning of Alexander Litvinenko.

Uranium atoms slowly decay into other atoms, eventually ending up as lead but with polonium as one stop on the way. Polonium-210 must be ingested or inhaled to cause damage - breathing it in, taking it into the mouth or getting it into a wound. And because the radiation has a very short range, it harms only Po-210 is a naturally occurring radioactive material. It is found in very low concentrations in the environment as a part of the uranium decay chain and can be Polonium-210 (Po-210) is a radioactive element that occurs naturally and is present in the environment at extremely low concentrations.

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.
