WebNov 23, 2024 · While potassium contents were estimated from the peak of 40 K at 1.461 MeV (energy range 1.366 keV–1.564 keV), there were several radioactive isotopes in the uranium and thorium decay series. Thus, we used “equivalents” of uranium and thorium, assuming secular equilibrium.
WebWhat is a natural decay series? 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. pucker palsWebThe most common thorium isotope is 232 Th, t ½ 14x10 9 years by α decay with accompanying γ radiation. 232 Th is the top element of a long decay series ending with stable 208 Pb, 228 Ra is the first decay product as described above.
