LIQUIDATION OF THE NUCLEAR LEGACY: RADIATIONHYGIENIC SAFETY CRITERIA FOR THE DECONTAMINATED SITES OF TERRITORIES, BUILDINGS AND CONSTRUCTIONS

Abstract

The article presents approaches to the establishment of criteria (requirements) of radiation safety to the decontaminated areas of the territory, buildings and decommissioned facilities of use of atomic energy and other types of practical activities with sources of ionizing radiation. The main directions of further use of the decontaminated areas of the territory, buildings, and constructions, including 5 scenarios of restricted and unrestricted use, are determined; the criteria of radiation safety in the term of a dose constraint of a critical group of the population in 0.3 mSv/year living or working on decontaminated objects are established; the controlled parameters of the radiation situation and their levels, as well as the list of radionuclides subject to control are justified. The article presents the values of specific activity (Bq/kg) of residual radioactive contamination of soils and materials of buildings and structures, the radiation dose to the population in which will not exceed 0.3 mSv/year. Based on the presented data, draft sanitary rules and guidelines have been developed.
