Analysis of in-diffusion of 241Am in concrete by an inverse technique
Original language description
Apparent diffusion coefficients of decaying radionuclides transported in saturated porous media can be evaluated by an inverse technique based on the Boltzmann-Matano method. Here this technique is applied to obtain concentration dependences of the apparent diffusion coefficient of 241Am for which the corresponding concentration profiles were measured for two types of concrete. These general results are compared with those from the original study in which the diffusivity was constant. Three types of simple functions are used to approximate the experimental concentration profiles, and the corresponding dependences of the diffusion coefficient on concentration are given via quite simple formulas. Although being different at low and high concentrations, they all provide similar results within the intermediate range.
