How is polonium used
Polonium is a chemical element with the symbol Po and atomic number 84. A rare and highly radioactive metal with no stable isotopes, polonium is a chalcogen and is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: … Meer weergeven Po is an alpha emitter that has a half-life of 138.4 days; it decays directly to its stable daughter isotope, Pb. A milligram (5 curies) of Po emits about as many alpha particles per second as 5 grams of Ra, which means it is … Meer weergeven Tentatively called "radium F", polonium was discovered by Marie and Pierre Curie in July 1898, and was named after Marie Curie's native land of Poland (Latin: Polonia).
