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.
