A review is given of some aspects of radioecology and its importance in agriculture. A suggestion is made for developing radioecological study as a separate branch of science. (R.V.J.)

Radioactive isotopes of iodine are Produced during nuclear fission in reactors and in weapons tests and to a limited extent in nature. Because of its extremely long half-life (1.6 x 10/sup 7/ yr) 1291 has the potential for accumulation in the environment from longterm, chronic releases from nuclear facilities. Possible problems associated with such an ...

Radioecological sensitivity and variability are quantities that are used to characterize the radioecological properties of environmental samples. The radioecological sensitivity is the infinite time-integrated radionuclide concentration in the environment...

In this paper, we analyze the results of long-term investigations of 137Cs accumulation in the specimens of fish of the highest trophic level, pike and pike perch, from the reservoirs suffered as a result of the ChNPP. Annual, seasonal and age peculiarities of accumulation of the 137Cs specific activity in the predatory fish from the Kiev reservoir and ...

This article describes major studies performed by the Chernobyl Center's International Radioecology Laboratory (Slavutich, Ukraine) on radioecology of murine rodents and shrews inhabiting the Chernobyl Exclusion Zone. The article addresses the long-term (1986-2005) and seasonal dynamics of radioactive contamination of animals and reviews interspecies ...

The influence of low doses of radiation on the biological changes in the population groupings of rodents is traced. Correlative dependence between the factors of accumulation of 137Cs by animals in contact with the forest litter and vital functions: intensity of reproduction, death of young animals (Sad) and size was found at the example of Clethrionomys glareolus Schreb. ...

The features of the spatial distribution, of the migration, and of the accumulation of natural (232Th) and manmade (137Cs) radioactive nuclides in the coastal landscapes of the Sea of Azov are studied. It was shown, that the specific activity of 232Th in the accumulation of the so-called "black sands" was shown as high as 6000 Bq/kg, that increases the ...

Species-specificity and dynamics of 90Sr, 137Cs and some transuranic elements accumulation in bivalve and gastropod freshwater molluscs of the Chernobyl exclusion zone during 1997-2008 was analyzed. The results of radiation dose and chromosome aberration rate estimation and the analysis of hemolymph composition of freshwater snail (Lymnaea stagnalis L.) was produced. The ...

This article deals with the problems, connected with the formation of radioactive deposits in sewage (D.S.). It's shown that the main places of the accumulation of D.S. are the fields of filtration, silty sites and biological pools. In order to reduce the extent of the risk of the secondary contamination of environment we could offer the modernization of the elements of the ...

The research findings summarized in the paper include data on the radioecological conditions in two lakes (Large Ighish and Small Ighish) located on the East Urals Radioactive Trace. The focus of the study was on the chemical composition of water and bottom sediments, as well as on the specific features of 90Sr and of 137Cs distribution and the forms in which they occur in ...

The radioecological role of amphibians in freshwater environments was studied. Three distinct aspects were studied: (1) the metabolism of radioecologically important radionuclides in amphibians; (2) the effect of acute doses of radiation on adult amphibia...

Results on estimation of modern radioecological situation at nuclear explosion "Chagan" based on large-scale cartographic studies (1:25000) of a test area (4 km2) are presented. Maximum gamma-irradiation doses were observed at bulk of ground surrounded a crater and at radioactive fall-outs extended to the North-East and to the SouthWest from the crater. Based on data on ...

Translation of Radioekologiya by N. Kaner and H. Mills. Separate abstracts were prepared for the 17 chapters of the book. In addition, there is an introduction in which the general principles of radioecology are discussed. (HLW)

Chemical analyses and radioecological methods were combined in order to estimate the sediment accumulation rate in the upper 20 cm depth of the Palmones River estuary. Organic matter, total carbon, C:N and (137)Cs vertical profiles showed changes at 13 cm depth. These changes could be associated with the decrease in river input since 1987 when a dam ...

The accumulation of Sr/sup 90/, Ce/sup 144/, Cs/sup 137/ and Ru/sup 106/ in Charophyta depends on the species, while accumulation of Sr/sup 90/ and Cs/sup 137/ depends on sampling time and vegetative period. The accumulation and excretion of Sr/sup 90/ and Cs/sup 137/ in Charophyta depend both on the exchangeable calcium and potassium ...
