鉛の同位体
1. Isotopes of leadLead (Pb) has four stable isotopes: Pb, Pb, Pb, Pb. Lead-204 is entirely a primordial nuclide and is not a radiogenic nuclide. The three isotopes lead-206, lead-207, and lead-208 represent the ends of three decay chains called the uranium series (or radium series), the actinium series, and the thorium series, respectively. These series represent the decay chain products of long-lived primoridal U-238, U-235, and Th-232, respectively.
