title: Radon diffusion in model tests on Finnish esker and till soils.
abstract: In this paper, 222Rn activity has been investigated in some Finnish esker and glacial till areas. Model tests have been carried out to study soil parameters such as the 222Rn production rate, the 222Rn diffusion coefficients, and the 222Rn exhalation rate. The general differential equations for diffusion have been solved with different boundary conditions. Diffusion coefficients calculated from different experimental tests are comparable to each other.
