Le polonium est l'élément chimique de numéro atomique 84 et de symbole Po. Polonium (IPA: /pə (ʊ)ˈləʊniəm/) is a chemical element in the periodic table that has the symbol Po and atomic number 84. A rare radioactive metalloid, polonium is chemically similar to tellurium and bismuth and occurs in uranium ores.
