Abstract: The article analyzes 137Cs contamination of floodplain sediments of the Techa River and the middle courses of the Yenisei River as a result of discharges from the nuclear fuel plants. The results of field studies, both radiometric survey and sampling, are analyzed. The landscape differentiation of 137Cs contamination depends on specific features of suspended matter deposition on the floodplains. A secondary contamination zone was identified for the Techa River (up to 0,7 m) which was formed due to erosion of alluvial soils in the Asanov bogs and subsequent transfer of bottom sediments. Correlation between radionuclide contamination and duration of inundation for particular floodplain segments during 1960-2000 was analyzed for the Balchug floodplain area (the Yenisei River).

Abstract: The article provides the results of a comparative analysis of radionuclides (226Ra, 232Th, 40K, 137Cs). It reveals the consistent patterns of their activity distribution (the content) in the profile of chernozems exploiting in agriculture and their analogues under forest (field-protective forest) and old idle land. The soil samples were selected in Volgograd, Rostov and Orenburg regions and Republic of Bashkortostan.

Abstract: The article presents the results of radiogeochemical studies carried out by IGEM RAS in the Kara Sea and the estuaries of Ob and Enisey rivers in 1995-2003, specifically on Akademik Boris Petrov research vessel. Based on the studies of circa 1500 samples of bottom sediments, obtained from 172 sea and rivers stations, 137Cs distribution map in the surface sediments was created. Four zones of radiocesium overactivity (> 15 Bk/kg) were identified: Novaya Zemlya Zone, Vaigach Zone, Ob Zone and Yenisei Zone. The allocated zones have different radiocesium concentration levels, as well as different infl ow sources, but all of them were generated under the influence of complex geochemical barriers. Based on the 47 sectioned cores of bottom sediments research, sampled in Ob Zone and Yenisei Zone overactivity zones, the distinct differences in vertical radiocesium distribution were identifi ed. It is evidenced that these differences are caused by oscillations of suspended silt discharge over the years, which are main transfer agents of radiocesium dissolvable and semi-dissolvable forms and doesn’t depend on sedimentation circumstances as well as on geochemical characteristics of depositing environment.

Abstract: The paper deals with the development of a highly sensitive method for determining plutonium isotopes (238Pu, 239Pu + 240Pu, 242Pu) in the solid samples of environmental objects with preliminary radiochemical preparation. The chosen conditions for preparation of samples permit effective separation of plutonium from mixing alpha-radiating radionuclides and allow plutonium to release in the radiochemically pure form to a sample to be calculated. Spectrometric measurements of the calculated samples and identification of isotopes were made on a “Progress-alpha” alpha-spectrometric unit having a silicon semiconductor detector. The developed procedure is rather reliable in identifying and estimating the content of major plutonium isotopes in the soil and bed deposits at their background values (1 Bc/kg or higher). The paper presents the results of analysis of samples of the soil selected during radioecological monitoring in the South-Western Okrug of Moscow, as well as the alpha-spectra obtained.
