Abstract
An equation is presented for predicting solid/liquid distribution coef ficients of radiocaesium on soils and sediments (freshwater and marine ). The equation is based on the value of the radiocaesium interception potential of the illitic frayed edge sites of the system and liquid p hase composition (K, NH4 and Na). The predictive potential of the equa tion is tested for some 130 combinations of soil/sediment and water co mposition covering a three-order-of-magnitude range in K-D(137Cs) valu es. On average, experimental K-D(137Cs) values exceed predicted values by a factor of 1.62 +/- 0.75. Copyright (C) 1996 Elsevier Science Ltd
