Abstract
An experimental installation simulating nuclide diffusion in granite with single fracture is developed. The experiment of 125 I -, 134 Cs + diffusion in granite rock with single fracture is made. Based on given conditions, the diffusion coefficient and radioactive strength distribution on nuclide adsorption by its surface are obtained.
