- Abstract
- The content of artificial gamma-emitting radionuclides (137Cs, 134Cs, 154Eu, 155Eu, 60Co, 241Am, 243Cm) in the "hot" particles found in the near zone of influence of the Krasnoyarsk HPP was determined. In the course of laboratory and field experiments it was shown that while in natural conditions of occurrence in flooded soils of the floodplain part of the Yenisei river, "hot" particles under the action of filtered water and moisture of pore solutions gradually dissolve, and the 137Cs included in their composition is involved in re-migration.
