Bismuth half life
Web210 Po is an alpha emitter that has a half-life of 138.4 days; it decays directly to its stable daughter isotope, 206 Pb. A milligram (5 curies) of 210 Po emits about as many alpha particles per second as 5 grams of 226 Ra, [4] which means it is 5,000 times more radioactive than radium.
