Correcting for Radon and Thoron Decay Product Contribution to Gross Alpha or Beta Counts-life) would have decayed away. The second count is also due to the “licensed material” and long lived naturally occurring airborne radionuclides plus thoron (Rn-220) decay products. However, the thoron decay products have decreased in activity. 30 OSTI.GOV Journal Article: Energy-dependent etching-related impacts on CR-39 alpha detection efficiency for the Rn-222 and Rn-220 decay chains 2017-07-01 2020-01-30 · Decay properties Radon-222 is generated in the uranium series from the alpha decay of radium-226, which has a half-life of 1600 years. Radon - 222 itself alpha decays to polonium-218 with a half-life of approximately 3.82 days, making it the most stable isotope of radon .
