fraction of potential alpha decay energy of the short-lived radon decay products, compared to secular equilibrium. The equilibrium factor is defined as: F = (0.106 c Po-218 + 0.514 c Pb-214 + 0.380 c Bi-214) / c Rn-222 where c x stands for the activity concentration of the nuclide x. Typical values are 0.4 for indoors or work, and 0.6 for outdoors.

Gaseous radon-222 will escape from the capsule through diffusion so the capsule, when not in use, should be kept in the vial. None of alpha or beta particles from decay of radon-222 and its progeny escape from the closed glass vial. The total activity of radon-222 and its progeny inside the vial is approximately 23 Bq.

Radon 222 formula

X1, X2, X3 are the decay constant of uranium-238, radium-226, radon-222. 238 U (4,5 x 10 9 år) → 234 Th (24,1 dage) → 234 Pa (1,18 min) → 234 U (250.000 år) → 230 Th (75.000 år) → 226 Ra (1.600 år) → 222 Rn (3,82 dage) → 218 Po (3,1 min) → 214 Pb (26,8 min) → 214 Bi (19,7 min) → 214 Po (164 µs) → 210 Pb (22,3 år) → 210 Bi (5,01 dage) → 210 Po (138 dage) → 206 Pb (stabil) radon-222. [ ′rā‚dän ‚tü′twen·tē‚tü] (nuclear physics) The isotope of radon having mass number 222, symbol 222Rn, which is a radioactive member of the uranium series with a half-life of 3.82 days. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. Want to thank TFD for its existence? Gaseous radon-222 will escape from the capsule through diffusion so the capsule, when not in use, should be kept in the vial. None of alpha or beta particles from decay of radon-222 and its progeny escape from the closed glass vial. The total activity of radon-222 and its progeny inside the vial is approximately 23 Bq. The equation for the alpha decay of 222Rn is: 86222Rn --> 84218Po + 24He Where He represents the alpha particle, which can also be viewed as a Helium nucleus.
