Title: A method to determine the isotopic ratio of thorium<sup>232</sup> to Thorium<sup>230</sup> in minerals
Abstract: The isotopic ratio of Th 232 to Th 230 was determined in uranium minerals. The thorium was separated from the mineral. The amount of Th 232 was determined by activation analysis and that of Th 230 by counting its a particles. The ratio of the two isotopes was calculated by comparing the β and α activity of the two thorium isotopes in the sample to those of a standard of known Th 232 to Th 230 ratio.
