As part of an ongoing project to assess the population dose from indoor radon and its daughters in India, a set of parallel measurements was made in more than 150 houses of different types to estimate indoor radon and progeny levels. Time-integrated solid state nuclear track detectors were employed for the measurement of radon concentration and potential alpha energy exposure level. From these values the equilibrium factor (F) between radon and its progeny was estimated for each house. An average F value of 0.39 was obtained.
作为印度一项正在进行的评估室内氡及其子体所致人群剂量项目的一部分，在150多所不同类型的房屋中进行了一组平行测量，以估算室内氡及其子体水平。采用时间积分固态核径迹探测器测量氡浓度和潜在α能量暴露水平。根据这些值估算了每所房屋中氡与其子体之间的平衡因子（F）。得到的平均F值为0.39。
