Detection efficiencies of the CR-39 and LR-115 type II solid state nuclear track detectors (SSNTD) for alpha-particles emitted by radon, thoron and their decay products inside the air of different dwelling rooms and in various reference atmospheres were determined by using a Monte Carlo computer code. Alpha- and beta-activities per unit volume of air due to radon, thoron and their progenies were measured in the studied atmospheres by exploiting data obtained for the detection efficiencies of the SSNTD and measuring the resulting track density rates. Equilibrium factors between radon and its progeny and thoron and its daughters were evaluated in the studied atmospheres.
利用蒙特卡罗计算机代码，测定了CR - 39和LR - 115 II型固态核径迹探测器（SSNTD）对不同居室空气和各种参考大气中氡、钍射气及其衰变产物发射的α粒子的探测效率。通过利用SSNTD探测效率的数据并测量所得的径迹密度率，在研究的大气中测量了由于氡、钍射气及其子体导致的每单位体积空气中的α和β活度。在研究的大气中评估了氡及其子体以及钍射气及其子体之间的平衡因子。
