EXPERIMENTAL DETERMINATION OF TRITIUM MATRIX DIFFUSION COEFFICIENT IN THE SAMPLES OF RAPAKIVI-LIKE-GRANITE
Abstract
Effective (matrix) diffusion coefficient and effective porosity are the key parameters in order to describe the diffusion mass transfer of contaminating components in low-permeable crystalline rocks. The experimental method on determination of parameters was chosen and approved. Values for effective diffusion coefficient of tritium and effective porosity of rapakivi-like-granite samples taken from Omelianivsky quarry were calculated.
