A milligram of polonium-210 emits as many alpha particles as 5 grams of radium. A great Bismuth-214 (19.7 minute half life) yields a beta particle and Polonium-214; Polonium-214 (0.16 millisecond half life) yields an alpha particle and Lead-210; Polonium-210 decays to lead-206. Polonium (Po) has atomic number 84 and lead (Pb) has atomic number 82. Which type of decay occurs? Reveal answer.
