Abstract

Purpose. Evaluation of radiation exposure to workers during the work on clearing the Konoplyanka River., which is necessary for the safe performance of work. Methods. For the purposes of assessment of radiation impact on the method of calculating the effective dose was developed by employees, which considered the following ways of working exposure: external exposure of staff and workers; internal exposure by inhalation of radionuclides number of uranium and thorium and actinouranium; internal exposure from radon and its decay products; internal exposure by oral intake of radionuclides. Results. The problems of radiation hazard events on clearing the Konoplyanka River., who was for a long time silting and covered with waste containing naturally occurring radionuclides uranium series. The method of calculating the doses employed in areas contaminated by natural radionuclides. Studies and calculations showed that the annual effective dose during the work on clearing the g .. Linnet to prevent flooding of the tailings will be 113.178 μSv, including external exposure - 94.86 μSv, internal exposure -18.318 μSv. In connection with this, works will not result in increased exposure of workers and the working conditions can be qualified as "acceptable" (class 2). Special measures to ensure radiation safety conditions of conducting works on clearing the g .. Linnet to prevent flooding of the tailings are not needed. Scientific novelty. We propose a method of calculating the doses employed in areas contaminated by natural radionu-clides. Practical significance. The calculations of dose downloads working at clearing the Konoplyanka River,contaminated with natural radionuclides of uranium series, and concluded that there is no danger at work.
