摘要
采用一维扩散模型研究了室内、子体和及其子体平衡因数 (FTh)的分布规律。讨论了FTh随墙面析出率、室内通风状况和空气含尘状况的变化。介绍了通过选取合适的FTh,由暴露量直接估算子体所致有效剂量的方法。
The distribution characteristics of indoor thoron,thoron progenies and their equilibrium factor F _Th were studied by using the theoretical model of one-dimentional diffusion. The variations of F _Th with exhalation rates of thoron from wall surfaces,indoor ventillation rates and indoor dust concentrations were discussed. If a suitable F _Th is determined,the effective dose to thoron progenies can be calculated based on thoron exposure.
