The Formation of Initial Gradients of 137Cs Concentrations in Soils at the Aggregate Level

Fokin, A. D.; Torshin, S. & Kaupenjohann, M.

Abstract: The initial concentration of 137Cs on the surface of soil aggregates has been confirmed by direct and indirect experiments. The thickness of the surface adsorbing layer has been approximately evaluated. The general pattern of 137Cs distribution on soil aggregates in the A1 horizon of soddy-podzolic heavy loamy undisturbed soil has been obtained using the autoradiography method. The possible effects of the formation of initial gradients of 137Cs concentration in the soil are discussed.
