Web2.2. Measurement of thoron concentration in pure thoron conditions In pure thoron conditions without interference of radon, the counting rate of alpha particles simply follows the law of 220Rn decay in the few minutes after sampling, because 212Pb has a much longer half-life than that 220Rn, while the lifetime of 216Po is much shorter than that ... Webpurposes. They are also radioactive: half of a collection of radon atoms disintegrate in 3.825 days, their mean life is 5.52 days, and 90 percent disintegrate in 12.7 days. Thoron decays more rapidly: it has a half life of about 54.5 seconds, a mean life of about 78.6 seconds, and 90 percent disintegrate in about 181 seconds. Actinon

WebMar 14, 2024 · Discovered in 1900 by German chemist Friedrich E. Dorn, radon-222 (3.823-day half-life), the longest-lived isotope, arises in the uranium series. The name radon is sometimes reserved for this isotope to distinguish it from the other two natural isotopes, called thoron and actinon, because they originate in the thorium and the actinium series, …
WebWhether in Asia, Europe or Latin America: An ever increasing number of geological and epidemiological studies are turning their attention to the short-lived radon isotope Rn-220 (half life T½ = 55 s) - also called "thoron" - which has so far hardly received any consideration.
