Measured surface-alpha activity on glass exposed in radon chambers and houses has a linear correlation to the integrated radon exposure. Experimental results in chambers and houses have been obtained on glass exposed to radon concentrations between 100 Bq m-3 and 9 MBq m-3 for periods of a few days to several years. Theoretical calculations support the experimental results through a model that predicts the fractions of airborne activity that deposit and become embedded or adsorbed. The combination of measured activity and calculated embedded fraction for a given deposition environment can be applied to most indoor areas and produces a better estimate for lifetime radon exposure than estimates based on short-term indoor radon measurements.
在氡室和房屋中暴露的玻璃上测得的表面α活度与累积氡暴露量呈线性相关。在氡室和房屋中，已对暴露于100 Bq m⁻³至9 MBq m⁻³氡浓度下数天至数年的玻璃进行了实验。理论计算通过一个模型支持实验结果，该模型可预测沉积并嵌入或吸附的空气中放射性活度的分数。对于给定的沉积环境，测量活度和计算出的嵌入分数的组合可应用于大多数室内区域，并且与基于短期室内氡测量的估计相比，能对终身氡暴露给出更好的估计。
