Thorium vs Uranium Nuclear Power
Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the isotope has the longest halflife ( x 10 10 years) of all isotopes with more than 83 protons. In fact, its halflife is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides.. 232 Th decays via alpha decay into 228 Ra .
