The Argun Production Mining and Chemical Association is a multi-activity mining company which perfprms 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 develop criteria for the site remediation, independent radiation hygienic monitoring is being carried out over some years. The researches performed showed that there is a significant excess of 226Ra and 232Th content compared to areas outside the zone of influence of uranium mining.
