Abstract

Simple mathematical ways of calculating the radon concentrations in walls and ground are presented. The methods exploit Fick’s second law in describing radon diffusion inside walls and ground. For both cases, a 1-dimension diffusion is adopted, with including advection in the ground case. The obtained forms fit the experimental data. Radon concentration inside a wall is employed to assess the decreased indoor gamma absorbed-dose rate from walls due to radon release. For describing radon diffusion through a building material sample, a 3-dimension diffusion is treated. Radon exhalation rates are suggested to be calculated from walls rather than building material samples.
