Some aspects of environmental hazard due to uranium mining in Ukraine


 Some aspects of environmental hazard within uranium mining areas are considered. The content in the environment components (rocks, soils, underground and surface waters) central part Ukrainian Shield beyond area is analyzed on example Michurinske ore field. It emphasized that man-made sources natural origin should be considered more broadly than just waste dumps from processing enterprises. These ionizing radiation origin, which have been subjected to concentration or their accessibility has increased because anthropogenic activity. Additional irradiation background formed. Waste as potential dust pollution layers atmosphere with fine containing uranium, its decay products associated elements. calculated using space images. Uranium accumulates dusty fraction, where 0.01-0.06%. Taking into account geological geochemical characteristics deposits, radioactive elements, heavy metals other elements mineralization car- ried out by winds atmospheric waters subsequent migration components.
