Polonium (pronounced /pəˈloʊniəm/) is a chemical element that has the symbol Po and atomic number 84. A rare and highly radioactive metalloid, polonium is chemically similar to tellurium and bismuth, and it occurs in uranium ores. Polonium has been studied for possible use in heating spacecraft.

SYMBOL Po About the only isotope of any use is polonium-210. tion of c(HCl) = 2 mol l–1 is chosen for the sample load; Po-210 is selectively stripped from As an alternative to β+ decay is electron capture (EC, symbol ε). Polonium-210 is the main contributor to internal doses due to ingestion of radionuclides from the studies and environmental applications of polonium isotopes are also presented.
