The effects of water-rock interaction and transport mechanism on the limits of radionuclide migration through aquifer rocks are considered. The consideration is based on an analysis of analytical solutions of simultaneous differential equations that describe radioactive decay, infiltration and diffusion transport of radionuclides, and radionuclide fixation on rock minerals and takes into account the kinetics of water-mineral radionuclide exchange reactions. The model is applied to calculate the limits of Sr-90 and Cs-137 migration.
