In recent years, polonium made 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. Polonium-210 has many uses but is most well-known for its use in static eliminators. These devices, which have a very small amount of the radioactive material mixed in a matrix and put on a foil, are used in manufacturing environments to In alpha decay Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82). 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.
