The data of monitoring the radiation and chemical situation in the middle reach of the Yenisei River have been included in mathematical calculations of the mass transport artificial radionuclides. Now we have the calculation algorithm for the mass transports artificial radionuclides in the river flow, including the suspended and bottom sediment dynamics, which can be used to simile river systems. The calculations showed that the concentration of the lightest fraction of the water on the current site remains virtually unchanged and those concentrations of suspended sediment decreases for heavier fractions decrease and, consequently, decreased the level of contamination. Our field data indicated an increase in the concentration of coarse fraction, which was associated not only with the resuspension-deposition, as well as with the coagulation of suspended solids.
