A method of mobility and ionic lifetime measurement of alpha emitters from the 228 Th/ 220 Rn decay chain is presented. The choice of 220 Rn chain over ²²²Rn is based on the fact that the shorter nuclear lifetime of ²²⁰Rn and ²¹⁶Po allows for easy determination of their mobility and ionic lifetime in the setup described, assuming no isotopic impact on the

Prior research reported the CR-39 detection efficiency for alpha particles from Rn-222, Rn-220 and their progeny under a variety of etching conditions. This paper provides an explanation for interesting observations included in that work, namely that the critical incidence angle decreases with The radon isotopes form chains of daughter decay products (or progeny), which have the properties of metals and release considerable energy by alpha, beta, and gamma radiation (see Fig. 3.1 and Tables 3.4 and 3.5). Because of the different half-life times, the behaviors of 222 Rn (T 1/2 = 3.82 days) and 220 Rn (T 1/2 = 55.8 s) are lished by the Decay Data Evaluation Project (DDEP) which can be found in [1]. 2 Evaluation The natural radioactive Ra-226 decay chain includes 13 nuclides, ending at the stable isotope of Pb-206. In this work, the evaluation of gamma and alpha emissions were performed Fig. 1. Decay chain of Ra-226 evaluated in this work. element of 220Rn decay chain) which are contained in the soils, as will be explained in the following.

Decay chain for the formation and decay of radon-222. Whether or not they are attached to atmospheric aerosols, radon decay the decay chain through to 208Pb for the decay chains of the 220Rn is expressed by The isotope Cr–53 is produced by the beta decay of which of the following: a. 53Mn b. 54Cr c. 52Cr Radon-220 (220Rn) decays to polonium-216.

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.

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).
