Analytical procedures are presented which permit the determination of the Working Levels of the radon and thoron progenies with personal α-dosimeters and α-particle environmental monitors, operating on time integrating principles, from gross α-counts. Experiments have been carried out in an underground uranium mine and in a radon/thoron environmental chamber, specially designed for calibration purposes, to verify theoretical data. In general, and notwithstanding a number of complicating factors, fair to good agreement has been found between theoretical and experimental data. Experimental values have been found to be lower than theoretical values, an observation which is partly ascribed to plate-out of decay products in the instrument's sampling heads.
本文提出了分析程序，该程序可通过个人α剂量计和α粒子环境监测仪（基于时间积分原理运行），从总α计数中测定氡和钍子体的工作水平。该实验在一个地下铀矿和一个专门设计用于校准目的的氡/钍环境室中进行，以验证理论数据。总的来说，尽管存在一些复杂因素，但理论数据和实验数据之间存在相当好的一致性。实验值低于理论值，这一观察结果部分归因于衰变产物在仪器采样头中的沉积。
