6. Conclusions
Knowledge about natural laws of substance migration in the environment, expedition and experimental data of landscape structure and landscape-geochemical peculiarities of the territory make it possible to forecast the conditions of 137Cs and 90Sr migration in ecosystems. Our investigation corroborated once more the sensibility of using a landscape base for these prognoses.
The main landscape and landscape-geochemical characteristics, which have to be taken into consideration, are: landforms, soil texture, washing out of soils, soil gleying, quantity of organic matter, regime of humidity of ecosystems, actual vegetation, edaphical conditions.
The maps “Carrying out, transport and accumulation of 90Sr and 137Cs” show ecosystems with a different transfer conditions, including areas of active water- and biogenic accumulation of the contaminants. These potential zones of contamination were recommended to be included into a radioecology monitoring net of the NPP 30-km zones.
The results of this investigation can be used for the estimation of migration conditions of radionuclides, other technical pollutants and their complexes as well.
