Abstract:
The ionizing radiation throughout all time acted as the main external factor in evolutionary
process. Today in many regions owing to radioactive pollution the general background
appeared under the influence of technogenic sources of the ionizing radiation.
Not only workers of the uranium industry, as well as the public of regions living near places of
production and processing of uranium ore can be subject to threat of influence of small doses of
radiation. Long-living radionuclides of technogenic origin make the main contribution to formation
of a dose of external and internal radiation.
