ポロニウムの同位体
1. Isotopes of poloniumPolonium (Po) has 42 isotopes, all of which are radioactive, with between 186 and 227 nucleons. Po with a half-life of 138.376 days has the longest half-life of naturally occurring polonium. Po with a half-life of 103 years has the longest half-life of all isotopes of polonium. Po and Po (half-life 2.9 years) can be made through the alpha, proton, or deuteron bombardment of lead or bismuth in a cyclotron.
