ABSTRACT
Purpose: The Priargun Production Mining and Chemical Association is a diversified mining company which, in addition to underground mining of uranium ore, carries out refining of such ores in hydrometallurgical process to produce natural uranium oxide. In order to establish the strategy and to develop criteria for the site remediation, independent radiation hygienic monitoring is being carried out over some years.
Material and methods: We collected and studied samples of soil, aquatic environmental media (sediments, lake water), and drinking water.
Conclusion: The performed researches have showed that there is a significant excess of 226Ra and 232Th content in comparison with areas outside the zone of impact of uranium mines.
Key words: radioactive contamination, natural radionuclides, dose rate, samples of environmental media
