各种国家和国际调查表明，与室外相比，住宅内的氡水平有所增加，因此人们对其对人口健康的影响日益感到关切。为了评估吸入氡及其子体所产生的有效剂量当量，我们已经开始了一项方案，以测量孟加拉国家庭室内氡及其子体浓度。本研究采用固态核径迹仪对160多家不同类型住宅的氡浓度和潜在α能量暴露水平进行了测量。根据这些值，估计了每个房屋氡及其子代之间的平衡因子(F)。平均值为0.4
Various national and international surveys have demonstrated an increase in radon (Rn) levels, relative to outdoors, in dwellings and consequently there is a continuous growing concern about its health effects on the population. In order to evaluate the effective dose equivalent from the inhalation of Rn and its progeny, we have started a programme to measure the indoor radon and daughter concentrations in houses in Bangladesh. In the present study time integrated solid state nuclear track detectors were employed for the measurement of radon concentration and potential alpha energy exposure level in more than 160 houses of different types. From these values the equilibrium factor (F) between radon and its progeny was estimated for each house. An average value of 0.4 was obtained
