A numerical method for characterizing the time-dependent diffusion of radon in a porous material

  • 1. National Tsing Hua Univ., Taiwan (Taiwan, Province of China)

Description

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
