Abstract
Distribution of radiostrontium and radiocesium over organic substance of former river-bed silts, peats, clays and clay sands, meadow sods and marls, and limonite of valley deposits of the Sozh river was studied. Throughout the valley deposits, the pattern of radionuclide distribution over groups and fractions of organic substance shows that relatively high mobility of 90Sr is caused by its association with fulvic acids, whereas relatively low migration capability of 137Cs can be attributed to its association with humic acids and minerals.
