The change in 90 Sr concentrations in hydrobionts, water and bottom sediments of the Chernobyl NPP pond-cooler, the Kievskoe and Kakhovskoe reservoirs, the Northern-Crimean canal and the Black Sea after the Chernobyl NPP accident was studied. The env

In the present study, an effort is attempted to record the impact of chronic radiation on natural aquatic populations exposed to protracted doses (lower if compared to intervention levels but higher if compared to typical background) and to chemical

The 14C-dating of microbial carbonate structures growing at methane seeps in anoxic waters of the Black Sea has shown a gradual increase with depth of the age of carbonates of these buildups. Comparing the radiocarbon age of the base and middle parts

The deposition record of 137Cs was traced in the SE Black Sea sediments adjacent to the Coruh river mouth in comparison with the earlier studied chronology of 137Cs deposition in front of the Danube delta (NW Black Sea). In both cases, the 137Cs prof

The purpose of this study was an evaluation of the effect levels of various toxic agents compared with acute doses of ionizing radiation for the experimental model ecosystem, i.e., microcosm mimicking aquatic microbial communities. For this purpose,

The paper deals with the input and deposition of the man-made radionuclides 137 Cs, 238 Pu, 239+240 Pu and 241 Am introduced to the north-western Black Sea, over the last few decades, as the result of atmospheric nuclear weapons testing and the Chern

The radioactive contamination of the Techa–Iset rivers downstream from the MAYAK reservoirs has been determined by measurements of 90 Sr , 137 Cs and transuranic elements in floodplain soils and sorlake sediments. Empirical models for the spatial d

The paper summarizes studies of the distributions of 90 Sr and 137 Cs in the water and sediments of the Black Sea carried out during a 10-year period following the 1986 accident at the Chernobyl Nuclear Power Plant. Its goal is to assess the temporal

Some quantitative data on dose-effect or dose rate-effect relationships under conditions of chronic irradiation have been obtained in different investigations. A conceptual model of the biological responses to all magnitudes of dose rates of ionising
