A preliminary analysis of the available literature [2,4] data and assessments of current radiological conditions in the region of Min-Kush, there were identified the need to expand the exploring, which will create a conceptual model of the impact of the area with uranium legacy on the environment as a basis for further development of rehabilitation strategies.…”

Radioecological Assessment of the Uranium Tailings in Tuyuk-Suu (Kyrgyzstan). The aim of our research is the radioecological assessment of the current state of uranium tailings in Tuyuk-Suu. The methods of field and laboratory analysis were conducted with the modern radiological and nuclear physics equipment. Gamma survey was shown that the surface of the tailings Tuyuk-Suu and Taldy-Bulak may effectively reduce the exposure dose of gamma radiation, the body Tuyuk Suu is flooding with water flowing near the river in a concrete channel, so it should be constantly monitoring the state of the tailings and the river Tuyuk-Suu. In this article is given the analysis and estimates of the current radiation condition of the tailings dam and Min-Kush settlement. It was for the first time made the radiological analysis after closing of the uranium tailings in a body of the most tail material and it is estimated states possible pollution to environment.

“…Mining Enterprise of the Ministry of Average Machine Building of USSR for processing uranium ore there was in operation from 1948 to 1969, and was subsequently converted into the electrical engineering plant. The uranium oxide at this site is generated from the ashes of brown coals uraniferous sogutin filed as a by product for the electricity production from coal (5,15) Waste and industrial equipment have been buried, forming a tailings pond, with a total volume of uranium waste 400 000 m 3 , an area of 10 800 m 2 . Tailings from uranium waste is located 2.5 km east of the residential village, but due to natural factors (rain, groundwater, landslides and mudflows) is an environmental threat to lake Issyk-Kul (1.5 km from the lake) and the nearest towns located on slopes up to 30-45° between the mountains.…”

“…In modern literature, a number of studies are presented on the topic of pollution, migration, accumulation of radionuclides in the environment and their biological effect on living organisms. [6][7][8][9][10][11][12]. Based on the above, the aspect of the biological effect of natural concentrations of uranium and products of its decay on living organisms of the aquatic ecosystem of Lake Issyk-Kul is poorly studied.…”

This work is devoted to the study of the features of biogenic migration of natural radionuclides in the conditions of Lake Issyk-Kul located in the north-eastern part of Kyrgyzstan. Lake Issyk-Kul is a high-mountainous, thermal, drain less reservoir with brackish water with a high content of natural uranium. This is due to climatic conditions, the geological structure of river valleys, and the peculiarities of the composition of river waters capable of extracting uranium from rocks. Calculations using the Erica tool 1.3 software showed that the natural uranium content in the water of Lake Issyk-Kul (0.809 Bq/l) is safe for living organisms of the aquatic ecosystem, the level of absorbed dose, accumulation and risk factors vary within the normal range. According to the Erica tool 1.3 database, low radiation doses (0-50 μGy/h) can stimulate the growth of aquatic plants. The species composition of the ichthyofauna of Lake Issyk-Kul consists of 22 species of fish, including 12 aboriginal and 10 acclimatized. The content of natural radionuclides ( 226 Ra, 228 Th and 212 Pb) in the bone and muscle tissue of some fish species of Lake Issyk-Kul was investigated. It has been established that radionuclides are predominantly found in bone tissue in comparison with muscles, their concentrations vary within the limits of natural parameters.
