Thorium vs Uranium Nuclear Power

2020-9-22 · Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides.. 232 Th decays via alpha decay into 228 Ra .
