Abstract
Since 2010 Republic of Kazakhstan became the largest supplier of uranium in the world, having headed the list of leading producers of natural uranium.Reserves and resources of uranium in Kazakhstan make now about 1,7 million tons, or about 12% of the total amount of world reserves and uranium resources (according to IAEA). Out of sanitary protection zone of uranium mining deposits Mynkuduk, Uvanas and Moyunkum, Tortkuduk were carried out automobile and pedestrian gamma survey, measurement of density of streams alpha, beta particles, radio spectrometric and radiochemical analysis of tests of water and the soil.Out of sanitary protection zone of depositsMynkuduk and Uvanas of radioactive anomalies aren't found. At distance of 5 km from area No. 1 Moyunkum near a well is revealed an anomal area with an area of 93 sq.m where the power of an equivalent dose of gamma radiations varies from 0,41 to 1,43 μSv/hour. In the samples of the water which have been selected from an anomal area total alpha activity to 29 times, radium‐226 to 10 times, radium‐228 to 32 times exceeds standard value. In case of water use for an irrigation melon field and kitchen gardens, a cattle pasture on pollution areas, individual doses of internal radiation when using by the population in production food from these areas could reach values 20‐40 mSv / year an annual effective dose shouldn't exceed 1 mSv/year.
