This paper describes an experimental test of radon diffusion through a porous material, and a model created to calculate such diffusion. The material studied was Zeolite 4A, which was pressed into slab form, for used in diffusion measurements. The model is based on a nonlinear least squares and Marquardt method. The model has the advantage of giving diffusion results while the system is still in the transient state, and also offering a simpler calculational procedure.
