Summary
Thorium-232 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.

a. Neutron absorption by Th - 232 produces Th -233 which beta-decays (with a half - life of about 22 minutes) to protactinium-233 (Pa-233) – and this decays to U-233 by further beta decay (with…
