“…Long-lived radionuclides were developed from the excavation explosion, which concentrated in the soils surrounding the 'Atomic Lake' [17]. The specific activity of induced radionuclides is 4 000 Bq/kg at 241 Am, 15 000 Bq/kg at 137 Cs, 17 000 Bq/kg at 239+240 Pu, 10 000 Bq/kg at 90 Sr, 65 000 Bq/kg at 3 H, 20 000 Bq/kg at 152 Eu, and 13 000 Bq/kg at 154 Eu [18]. Despite the high radionuclide contents in the piling soils, radionuclides such as 137 Cs, 241 Am, 239+240 Pu and 152 Eu are practically not detected in the lake water.…”

The article presents the results of a study of groundwater contaminated with tritium in the vicinity of the ‘Atomic Lake’ - a crater filled with water as a result of a thermonuclear explosion on the territory of the former Semipalatinsk test site. This crater was created as part of an experimental thermonuclear explosion in 1965 with the aim of creating an artificial reservoir in arid areas. The study was carried out to identify the source of groundwater contamination near the crater formed from a thermonuclear test. There were two possible factors of pollution: the influence of contaminated water from the crater on the groundwater of the adjacent area, or groundwater polluting the water in the crater. It was necessary to find out the source of groundwater contamination and its connection with the water in the funnel. For this purpose, a study of the geological and lithological conditions of the territory adjacent to the funnel was carried out, which was carried out using drilling operations and hydrological measurements. Drilling work made it possible to study the depth of distribution of groundwater, hydrological work made it possible to determine the conditions of distribution of groundwater, as well as to take samples of groundwater. The assessment of the degree of groundwater contamination was carried out through water sampling and laboratory analysis. As a result, it was established that the geological and lithological conditions of the area limit the flow of contaminated groundwater to the water in the crater - the ‘Atomic Lake’. Despite the fact that the waters in the crater from a thermonuclear explosion and the groundwater of the adjacent territory are contaminated with the radionuclide tritium, they have different sources of contamination and are not interconnected. Radionuclide analysis of groundwater showed that increased concentrations of tritium with a specific activity of up to 95 000 Bq/l are found in groundwater near the river bed. Shagan and this is due to the influence of the flow of groundwater coming from other parts of the landfill.

“…Between 1949 and 1989, 456 nuclear tests were conducted in the STS territory [1]. Those tests caused all environmental components to be contaminated both directly in test areas and beyond them (fallout in the form of plumes) [2][3][4][5][6][7][8]. 2008 through 2021, a comprehensive radioecological survey began in the Semipalatinsk Test Site territory, which was aimed at assessing whether it was possible to release a portion of the test site territory to the economic use.…”

Data on the vertical distribution of radionuclides in the soil is necessary to fully understand the radioecological situation around ecosystems, give predictive estimates to how safe crop products are and justify a rehabilitation strategy for radioactively contaminated areas. A study was conducted to investigate the vertical distribution of radionuclides in soils of the former Semipalatinsk Test Site (STS) territory beyond its testing sites, that is, in areas in which no nuclear weapons or nuclear effects of radiological warfare agents were tested. Soil was sampled layerwise all over the Semipalatinsk Test Site down to 30 cm deep at a 5-cm spacing. Most of high activity concentrations of radionuclides all over the study area were detected in the 0–5 cm soil layer. Activity concentrations of the major man-made radionuclides were determined in soil samples collected by γ-, β and α-spectrometry. As a result, ranges of activity concentrations of 137Cs, 241Am, 90Sr and 239+240Pu were determined in 0–5, 5–10, 10–15, 15–20, 20–25, 25–30 cm soil layers. In the conventionally ‘background’ area, the 0–5 cm soil layer, on average, contains (the percentage of total activity concentration across the soil profile depth): 137Cs– 83%, 239+240Pu– 87% and 90Sr– 38%. For the 1953 plume, these values were 92%, 83% and 73%, respectively. Values for the 1951 plume in the 0–5 cm soil layer were: 137Cs– 93%, 239+240Pu– 93% and 90Sr– 59%. The minimum concentration of radionuclides are observed 20–30 cm deep in all areas studied. 90Sr is the most mobile radionuclide from the perspective of its ability to travel deep down the soil. The study found out that the nuclide vertical migration rates downward in soils based on detected activity were as follows (in descending order): 90Sr– 137Cs– 239+240Pu– 241Am. Coefficients that determine the ratio of the activity concentration of the radionuclide in the 0–20 and 0–30 cm soil cover layers to that of this radionuclide in the 0–5 cm topsoil were calculated. These coefficients enable to estimate the radionuclide inventory at each soil sampling point from their activity concentration in the 0–5 cm soil layer.

“…Within the former Semipalatinsk Nuclear Test Site (further on STS), there are a number of water bodies that are characterized by the elevated content of man-made radionuclides and differ in a complicated formation mechanism (Subbotin et al, 2013;Larionova et al, 2017;Aidarkhanova et al, 2018;Gorbunova et al, 2012;Aidarkhanov et al, 2012;Subbotin et al, 2020). The main of these are common at the «Balapan» and «Telkem», which have surface waters from the Shagan riv.…”
