Short summary
The method for reconstructing the long-term dependence of radionuclide concentrations in rivers and reservoirs based on their vertical distribution in bottom sediments is proposed. Reconstructed time dependencies of particulate and dissolved Cs-137 activity concentrations in the Upa River were found to be described well by the semi-empirical “diffusion” model.
