摘要
本文运用一维扩散模型分析了室内220Rn及其子体浓度的分布规律,讨论了室内220Rn与其子体的平衡因子F的性质和变化规律。为评价220Rn子体的剂量贡献,介绍了通过选取适当的F值,由累计测量得到的220Rn浓度估算出子体平衡当量浓度的方法。
The distribution of indoor thoron and its progeny concentration was derived from a theoretical model of one-dimensional diffusion. And the characteristics of their equilibrium factor F were studied. It is expected from the discussion that the equilibrium equivalent thoron concentration could be calculated based on thoron concentration when a suitable F is determined.
