The estimation possibility of cleaning from radionuclides for the coast parts of drainage system by the soil fractionating method

In this paper is considered the possibility of the cleaning from the radionuclides for the coast parts of the drainage system at the Moscow SIA {open_quotes}Radon{close_quotes} by the soil fractionating treatment. It is showed that this method cannot to be used for the cleaning of the soils near water flowing (a river, a spring or a open drainage system) because the most part of the soil size-fractions is the fine fractions and the main contaminant radionuclide ({sup 137}Cs) is distributed among the different soil components homogeneously.
