Online radioactive decay calculator that allows you to find out the radioactivity decay in Thorium (Th) 228. Note: The calculation of radioactivity in minerals is based on certain assumptions. All are present, at least transiently, in any natural thorium-containing sample, whether metal, compound, or mineral. The series terminates with lead-208. The details in decay chain (symbol, atomic mass, number of protons, half-life, decay children) are taken from Wikipedia. Uranium, Radium, and Thorium Uranium, radium, and thorium occur in three natural decay series, headed by uranium-238, thorium-232, and uranium-235, respectively. In nature, the radionuclides in these three series are approximately in a state of secular equilibrium, in which the activities of all radionuclides within each series are nearly equal.

In general, naturally occurring thorium exists as Th-232, Th-230 or Th-228. Type of Radiation Emitted: Half-life Half-life The time required for half of the radioactive atoms present to decay or transform. Thorium 232 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.
