The analysis of the radiation environment of workplaces and personnel dose load hydrometallurgical plant of the Stepnogorsk Mining and Chemical Combine and the accumulated doses of the personnel group A. Studied the soil, water and plants in the area around workers’ settlements and uranium mining companies as well as sanitary protection zone of the tailings of radioactive waste. Identified local contaminated areas in the North-East of the sanitary protection zone of the tailings SPZT Stepnogorsk mining and chemical plant extending up to 5 km. The most contaminated with radionuclides is the top layer of soil 0-5 cm. In the North-East and South-East directions from SPZT specific activity of U238, Ra226 in soil exceed the reference value of 16 times, Pb210 up to 7 times. The plant samples taken from the vicinity of the village in the South-East and North-East directions from SPZT have high concentrations of natural radionuclides. In ponds and Sulukamysskogo Manybayskogo thalwegs specific activity of artificial radionuclides in the tens of times higher than the control values. © Medwell Journals, 2016.
