Mathematical model of radionuclides transfer in soil profile is described. The model makes it possible to take into account the role of the following factors and processes in radionuclide redistribution in soil profile: i) physico-chemical forms of radioactive fallouts; ii) different forms of transfer of radionuclides in soil profile (radionuclides which are constituents of fuel particles matrix; radionuclides presented at the soil solution as free ions and complex compounds; sorbed forms of radionuclides); transformation of the above-mentioned forms, including fuel particles destruction. An example of the model application for calculation of predictive assessment of 90 Sr, 137 Cs 239, 240 Pu redistribution in the profile of sodium-podzolic sandy loam soil at fuel track of ChNPP fallouts has been considered.
