摘要：
The activity concentrations of Po-218, Pb-214 and Bi-214 [i.e. C(Po-218), C(Pb-214), and C(Bi-214)] and the calculated concentration ratios [i.e. 1:C(Pb-214)/C(Po-218):C(Bi-214)/C(Po-218)] are necessary for assessing radon and its progenies exposure. In this study, a measurement method of radon progenies concentrations with both high sensitivity and low uncertainty, was developed based on the Kerr method. The field measurement results of radon progeny concentrations and calculated concentration ratios in both typical indoor and outdoor environments in Beijing, China, were reported. The effects of air exchange rate on concentration ratios of radon progenies in indoor environments were discussed.
