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.
Its atomic number 84 and its symbol is Po. The highly radioactive isotope of Polonium (Po-210) is … Polonium (84 Po) has 42 isotopes, all of which are
The first element to be discovered by radiochemical analysis, polonium was discovered in 1898 by Pierre and Marie Curie, who were investigating the radioactivity of a certain pitchblende, a uranium ore.

It is a scarce element that is produced in nuclear reactors. Neurons are used to bombard bismuth-209, and bismuth-210 is formed as a result. Polonium-210 is highly radioactive substance and a lethal poison.

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
Plutonium. Pu-238.
A rare radioactive metalloid, polonium is chemically similar to tellurium and bismuth and occurs in uranium ores. Polonium has been studied for possible use in heating spacecraft. It exists as a number of isotopes.
