232 Th is the predominant isotope of natural thorium. If this fertile material is loaded in the nuclear reactor, the nuclei of 232 Th absorb a neutron and become nuclei of 233 Th.The half-life of 233 Th is approximately 21.8 minutes. 233 Th decays (negative beta decay) to 233 Pa (protactinium), whose half-life is 26.97 days. 233 Pa decays (negative beta …Web
