Polonium-210 atom is the radioactive isotope of polonium with relative atomic mass 209.98286 and half-life of 138.376 days; the only naturally occurring isotope of polonium. 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).
