Firestone 1. 1 LBNL, Berkeley, USA 2 Department of Physics 2006-07-09 · Additional Th-228 is thus not introduced by the decomposition of Ra-228 while the Th-228 level gradually decreases as a result of decay into non-thorium decay products. The Ra-224 in the non-thorium fraction decays to Rn-220, a short-lived radioactive gas that may build up high levels of radioactivity in working areas. 228Th decay chain is important in quantifying the environmental impact of the decay of naturally- occurring 232 Th. Specific radionuclides in this decay chain are noteworthy because of their decay characteristics ( 224 Ra alpha decay to 220 Rn; 212 Bi and 208 Tl gamma-ray emissions). Radium-226 Decay Chain regulated by NYS & EPA -- except Rn-222. Fig. B. Radionuclides in the Radium-228 Decay Chain: regulated by NYS Sanitary Code & EPA’s Radionuclides Rule of 1976. POLONIUM CANCER RISK Exhibit A also includes cancer risk factors for several radionuclides found in LI groundwater, including Ra-228, Pb-210, Bi-210 & Po-210.

Radon-220 decay chain. 220 Rn is a decay product of the long-lived 232 Th isotope. 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.
