Lead-213 (Pb-213) is a short-lived radioactive isotope of lead with a half-life of about 10.2 minutes. It decays by beta-minus emission to bismuth-213. Because of its very short half-life, Pb-213 rapidly disappears after production and is mainly of interest in nuclear physics and studies of radioactive decay chains.
Pb-213 has no significant commercial or medical applications and is primarily used in nuclear physics research. Studies of Pb-213 and its decay to Bi-213 provide information about the properties and decay behavior of neutron-rich nuclei in this region of the nuclear chart.
Pb-213 does not occur naturally in significant quantities because of its very short half-life. It can be produced artificially in nuclear reactions and can also appear as the daughter product of Po-217 alpha decay. In practice, Pb-213 is encountered mainly in specialized nuclear research experiments shortly after its production.
