In the air of this area, the content of the main dose-forming radionuclides Ra226 exceeds the acceptable doze more than twofold. Besides, outside the sanitary-hygienic zone, dust and gas emissions of existing facilities of Eastern Mining Processing Plant cause increased Th230 content in the air when there are critical wind speeds (up to 9m/s).
There is a high radionuclide content in soils along the line of pulp feed-lines, as well as in the sanitary-hygienic zones of tailings « SHCH » and «KBZH».
The concentration of U238 in the surface C33 soil is 2.7 times higher than the background concentration, the concentration of Ra226 is 2 to 9 times higher, Pb210— 2 to 25 times, and Po210—2 to 17 times. In a westerly, easterly and northerly direction, the gross of radioactive impurity does not spread beyond C33. Souther, it is entirely possible the carryover of contamination beyond C33.
In the residential construction area, most of the territory is characterized by gamma-radiation intensity up to 0.17 mSv/h, that is, within background limits. However, in some areas there is a high content of radionuclides found in the sites of uranium mining waste use (rocks, out of balance ores) as a construction material for foundations of buildings, street pavement, perimeter walk, footpaths.
