N2 - The process of radon diffusion through slabs of concrete with different thicknesses is investigated. The solution of the relevant diffusion equation is obtained by the explicit finite difference method. It is compared to experimental measurements and to numerical results obtained by the finite element method reported earlier. A need is demonstrated to account for the elevated radon concentration in air immediately behind the concrete slabs as it affects the diffusion through the slabs. The method presented for the calculation of radon diffusion through concrete walls allows estimation of the indoor radon concentration. © 2007 Elsevier Ltd. All rights reserved.
