摘　　要：本文根据氡运移的扩散与对流理论建立了任意形状介质中氡运移方程、大地岩石、土壤中氡的运移方程和大地—大气氡交换理论模型。通过模型实验研究了介质中氡运移规律并验证所建立的氡运移的理论公式。运用大地—大气氡交换模型计算了江西临川市某住宅区空气中氡浓度 。On the basis of the theory of diffusion and convection of radon, the predent paper has formulated migration equations in arbitary media as well as in rock and soil near the surface, and set up a model for ground atmosphere exchange of radon.The migration regularity of radon in media has been studied and the theoretical equations verifield by model experimentation. The authors used the theoretical model to calculate the radon concentration of air at a certain residential area of Linchuan City, Jianxi Province, which has been preliminarily proved to the effective.
