Abstract
Two methods are proposed for estimating the exchange distribution coefficient of137Cs and90Sr in natural soil-water systems: effective selectivity and selective sorption of137Cs. Principles for classifying soils and deposits as a function of the effective selectivity coefficient are proposed. Using the first method, the90Sr distribution coefficient can be estimated if the sorption properties of the medium are known to within 50%; for137Cs. the distribution coefficient can be estimated only in order of magnitude. The uncertainty in the prediction of the137Cs distribution can be decreased by determining the characteristics of the selective sorption of137Cs: the capacity of selective sorption centers and/or the radiocesium interception potential. 3 tables, 8 references.
