the half-life of radon-222 is 3.8 days. How much of a 100g sample is left after 15.2 days? The half-life of radon-222 is 3.8 days. How much of a 100. g sample is left after 15.2 days? half-life = 3.8 days total time of decay = 15.2 days initial amount = 100.

Radioactive isotopes having masses ranging from 204 through 224 have been identified, the longest-lived of these being radon-222, which has a half-life of 3.82 days. Radon is a colorless, odorless gas, a radioactive byproduct of radium. It is part of the natural radioactive decay series starting with uranium-238.

The radon-222 isotope is a natural decay product of the most stable uranium isotope (uranium-238), thus it is a member of uranium series. The half-life of

23 Jan 2021 decay of radium, especially 222Rn in 226Ra decay (238U decay chain) half- life of 219RN is T219 = 3.96 s [1], which is obviously shorter than 

3H and 147Pm. Radiotoxicity is based on the biological half life and how the  Radon is a naturally occurring radioactive noble gas, the most significant isotope of which is radon-222 with a half life of 3,82 days. eur-lex.europa.eu. Its most stable isotope is Radon-222, which is a decay product of Radium-226. Radon-222, which has a half-life of 3.8 days, emits an alpha particle as it decays  av AS Lundensia — 222Rn decays with a half-life of 3.82 days to the following short-lived radon daughters: 222Rn (3.82 days) >218Po (RaA 3.10 min) > 214Pb (RaB 26.8 min)  Mätning av radioaktivitet i omgivningen – Luft: radon-222 – The radon-222 half-life (3,8 days) is long enough for it to migrate from the rock producing it,  The radon gas was trapped on cooled charcoal filters and the long-lived daughter products 222Rn decays with a half-life of 3.82 days to the following short.
