Gamma radiation and radon exhalation from the surface of radioactive tails of Tajikistan

The results of gamma radiation measurements and radon exhalation from the surface of radioactive tailings in Tajikistan have been presented in the article. An analysis of the results of work performed shows that at present, within the territory of northern Tajikistan, relatively high values of the volumetric activity of radon in the atmospheric air are observed in the areas where uranium tailings are located, primarily in the city of Istiqlol and the Digmai tailing. This circumstance is due, first of all, to the absence of protective coatings on the surface of the tailing material, which turns these areas into essentially radon-hazardous areas of man-made origin.
