In the last decade the high radon absorption ability of some polycarbonates has been successfully used to measure Rn in air, water, and soil-gas. This report describes a theoretical model of the response of Rn detectors that are based on radon absorption and electrochemical etching of alpha-tracks in polycarbonates. The model is based on the volume distribution of the absorbed Rn and the response function of electrochemically etched Makrofol. Theoretical expression for the calibration factor is obtained, and comparison with experimental results is made. The comparison demonstrates very good correspondence between theoretical and experimental values. The conclusion is that this model can be useful in design and optimization of Rn measurements based on absorption in polycarbonates.
在过去十年中，一些聚碳酸酯对氡的高吸收能力已成功用于测量空气、水和土壤气体中的氡。本报告描述了基于聚碳酸酯中氡吸收和α径迹电化学蚀刻的氡探测器响应的理论模型。该模型基于吸收的氡的体积分布和电化学蚀刻的Makrofol的响应函数。得到了校准因子的理论表达式，并与实验结果进行了比较。比较结果表明理论值与实验值非常吻合。结论是，该模型可用于基于聚碳酸酯吸收的氡测量的设计和优化。
