It is produced during the radioactive decay of radium-226, itself a decay product of uranium-238 found in many types of crustal materials, that is, rocks and soils. Rn-222 has a short half-life (3.8 days) and decays into a series of solid particulate products, known as radon progeny or radon daughters, all of which have even shorter half-lives (∼30 min or less). Each of the decay product isotopes in the decay chain has its own half-life, and once it is formed it begins its decay to the next isotope in the sequence. The half-life of radon-222 is only 3.8 days.

Rn 220 decay chain

The half life of 232 Th is 14 billion year. Thorium occurs in thorite and in thorianite and is thought to be about three times as abundant as uranium and about as abundant as lead. Solving a system of differential equations according to Bateman to calculate the relative activity of the products of the Rn-220 decay chain. Radon-220 or Thoron is a natural decay product of thorium. For the basics have a look at "Radioactive decay & Bateman equation".

As can be seen in Figure 1, 220 Rn decays by the emission of an alpha. tion comes from radon-222 produced from the uranium decay chain. Radon-222 4.21 Polonium-212 rates fit resulting from radon-220 emanation. .
