g sample is left after 15.2 days? Radon-222 is a radioactive gas with a half-life of 3.83 days. This gas is a health hazard because it tends to get trapped in the basements of houses, and many … Radon-222 is produced by the decay of radium and has a half-life of 3.8 days. Radon-222 has a half-life of 4 days, thus during the time of 12 days, the radioactive go through several half-life cycles, which is calculated as: See full answer below.

Thenumber 86 represents the element’s atomic number. RadTown Radon Activity Set EPA 402‐B‐19‐057 https://www.epa.gov/radtown/radtown-radon-activity-4-half-life-radon If we have Radan to 22 that begins with a mass of 150 mg, and after 11.4 days, it's now at 18.7 mg. We need to figure out how Maney half lives past one half life would correspond to the 150 g milligrams. Going to half of that 75 mg to half lifes would be the 75 mg going toe. The half-life of 3.82 days for Radon-222 is long compared with its first four decay products, as shown in Figure 2.3, and these decay products in air are unlikely to … 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.
