Konoplev, A. Bulgakov] A method is proposed for estimating the distribution factors of137Cs and90Sr in soil and deposits. The method is based on predicting the forms in which these radionuclides occur and estimating the exchange distribution factor. It is shown that fixation of the radionuclides is a reversible process. A model is proposed for the transformation of the chemical forms of137Cs and90Sr. including leaching from fuel particles, fixation, and remobilization. It is shown that a first-order kinetic model satisfactorily describes the transformation of the forms of90Sr as well as137Cs for time periods of about one month. For longer periods of time, a diffusion fixation model is best for137Cs. Recommendations are made for the key parameters for various types of soils. 1 figure, 2 tables, 11 references.
