thoron progeny - Opis:
- The exposure from radon, thoron, and thoron progeny was measured for 45 dwellings in high background radiation area in Takandeang, Indonesia with ambient dose equivalent rate ranging from 0.34 µSv•h-1 to 1.90 µSv•h-1 . The measurement was taken using passive radon and thoron discriminative detector and thoron progeny detector. This measurement was taken from November 2018 to October 2019, and within one month the detector would be replaced with a new detector. The concentrations of radon, thoron, and thoron progeny were calculated as 42–490 Bqm−3 , 20–618 Bqm−3 , and 4–40 Bqm−3 , respectively. The concentrations for outdoor were 49–435 Bqm−3 , 23–457 Bqm−3 , and 4–37 Bqm−3 , respectively, and the annual effective dose was 9.8–28.6 mSv•y-1 . Based on the result of Spearman’s correlations analysis between the indoor radon and thoron concentrations and between the indoor thoron progeny and thoron concentrations, we suggest that exposure to thoron cannot be predicted from exposure to radon, and the equilibrium equivalent thoron concentration has a large uncertainty when it is estimated from thoron concentration assuming a single thoron equilibrium factor.
