Thorium-232 - Wikipedia
网页Thorium-232 (232 Th) is the main naturally occurring isotope of thorium, with a relative abundance of 99.98%. It has a half life of 14 billion years, which makes it the longest-lived isotope of thorium. It decays by alpha decay to radium-228; its decay chain terminates at stable lead-208.

Decay chain - Wikipedia
网页In nuclear science a decay chain refers to the predictable series of radioactive disintegrations undergone by the nuclei of certain unstable chemical elements. Radioactive isotopes do not usually decay directly to stable isotopes, but …
Thorium Series - Thorium Cascade - Nuclear Power
网页The thorium series is one of three classical radioactive series beginning with naturally occurring thorium-232. This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved.
Thorium Decay Series - an overview | ScienceDirect Topics
网页The first series in Figure 1.2 is known as the thorium decay series, and consists of a group of radionuclides related through decay in which all the mass numbers are evenly divisible by four (the 4n series). It has its natural origin in 232 …
