Popis: In the article there are presented data of the study of the radiation situation on the territory and at premises of the “Electric Mechanical Plant” Company, one of the units of the former uranium mining and milling facility of the former Lermontov Almaz Production Association. At the area of waste rock dumps and off-balance ores, the radiation situation was shown to meet requirements of health regulations SP LKP-91.The radiation situation in 14 out of 15 observed workshops and office premises meets the requirements for the limitation of the public exposure to natural radiation sources in occupational conditions established by health regulations and norms SanPiN 2.6.1.2800-10. In one building (warehouse premises), the requirements for equivalent equilibrium volumetric activity of radon (EEVA) in indoor air are exceeded. Based on the annual EEVA of radon values the assessment of effective doses in the work of the personnel over the one shift, was shown to be overestimated up to 7 times due to the daily variation of radon volumetric activity concentration.
