WebThe α decay half-lives of odd-A and odd-odd nuclei ranging in 65⩽Z⩽112 are investigated by employing the modified universal decay law and the unified fission model, both of them take into account the contribution of centrifugal potential. Two radiometric dating methods involve thorium isotopes: uranium–thorium dating, based on the decay of 234 U to 230 Th, and ionium–thorium dating, which measures the ratio of 232 Th to 230 Th. These rely on the fact that 232 Th is a primordial radioisotope, but 230 Th only occurs as an intermediate decay … See more Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90.
