The influence of the sorptive properties of organic soils on the migration rate of {sup 137}Cs Chibowski, S; Zygmunt, J 54 ENVIRONMENTAL SCIENCES; CESIUM 137; FALLOUT DEPOSITS; ORGANIC MATTER; RADIOECOLOGICAL CONCENTRATION; RADIOECOLOGY; RADIONUCLIDE MIGRATION; SOIL CHEMISTRY; SOIL MECHANICS; SORPTIVE PROPERTIES Using a compartment model, the migration rates of {sup 137}Cs were calculated for two types of organic soils: a low peat-muck soil and a black earth. The migration rates of {sup 137}Cs in the tested soils turned out to be significantly higher than in mineral types examined earlier and ranged from 0.6 to 12.3 cm/year. The partition coefficients (K{sub d}) were also determined for samples with varying organic matter content (OM) that were taken from different layers of the studied soils. The experimental results indicate that there is a clear relationship between K{sub d} values and OM. The investigation was widened by microcalorimetric measurements which confirmed that the adsorption of {sup 137}Cs on the organic soils is low.
