Radon-222 (222 Rn, Rn-222, historically radium emanation or radon) is the most stable isotope of radon, with a half-life of approximately 3.8 days. It is transient in the decay chain of primordial uranium-238 and is the immediate decay product of radium-226 .
After 11 half-lives (42 days), radon radioactivity is at 1/2 000 of its original level. At this stage, the predominant residual activity is due to the radon decay product 210 Pb, whose half-life (22.3 years) is 2 000 times that of radon, and its descendants 210 Bi and 210 Po, totalling 0.03% of the initial seed activity.

Gentry noted that the 218 polonium radio halos only formed at temperatures below 300 degrees and were visible for less than 3 minutes, thus requiring the Precambrian granites where they are to have formed by a quick process yet "mysterious" [clarification needed] [13] cold, highlighting the singularities of the continental crust [14] [15] in relation to the oceanic crust.
