THORIUM 232 - From History to ReactorThis is a visual summary of all the information about thorium.Thorium is a weak radioactive element with atomic number 9 Twenty-seven thorium radioisotopes have been characterized, with a range in atomic weight from 210 to 236. All are unstable with the most stable being 232 Th with a half-life of 14.05 billion years. Thorium-232 represents all but a trace of naturally occurring thorium.

Its stability is attributed to its closed nuclear subshell with 142 neutrons. Thorium has a characteristic terrestrial isotopic composition, with atomic weight 232.0377 (4).

which are decay products of uranium-238, uranium-235 and thorium-232 As no reference standards and no reference materials are currently ISO 80000-10, Quantities and units — Part 10: Atomic and nuclear physics. Atoms with the same atomic number but different neutron numbers are called isotopes isotopes within Earth are potassium-40, uranium-238, and thorium-232.
