232 Th decays via alpha decay into 228 Ra . Distribution in ocean Thorium is a naturally occurring radioisotope, with four primary isotopes found in the ocean 232 Th (half-life 14 billion years), 234 Th (half-life 24.1 d), 230 Th (half-life 75,200 years) and 228 Th (half-life 1.91 years).. The major isotope is 232 Th, which has a primordial origin in the "big bang." The primary 232 Th source is deposition of dust at the sea surface.

232 Th is an α-emitter with a half-life of 1.40(1)×10 10 a, decaying through a branched series to 208 Pb Thorium is a chemical element with atomic number 90 which means there are 90 protons and 90 electrons in the atomic structure. The chemical symbol for Thorium is Th. Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. Thorium is moderately hard, malleable, and has a high melting point. Thorium-234 has 90 protons and 144 neutrons with a total atomic mass of 234 As Thorium-234 undergoes beta decay, a neutron becomes a proton.

Thorium 232 is the most common isotope of thorium in the nature. 232Th is a fertile isotope, but is not capable of undergoing fission reaction after absorbing thermal neutron. Thorium is a naturally-occurring chemical element with atomic number 90 which means there are 90 protons and 90 electrons in the atomic structure.
