RADIOMETRIC MEASUREMENTS OF CHANNEL SEDIMENTS IN THE MAMYSHONDON RIVER VALLEY
Introduction. The planned increase in anthropogenic pressures, as a result of the upcoming active construction work in the Mamyshondon river basin, will undoubtedly have an impact on the health status of the population of residential areas and the ecological state of the biota of coastal zones. The research purpose is to make measurements and fix the initial indicators of γ - radiation of these areas before the start of construction work. Material and research methods. Measurements of γ - radiation from the banks of the Mamyshondon river and its tributaries (Nardon, Lyadon, Zhymagondon) in the buffer zone and adjacent areas of the North Ossetian State Nature Reserve were carried out. It is planned to build a ski resort "Mamison" in these territories. For radiometric measurements, a γ - radiation dosimeter was used, namely the Geiger - Muller counter DKG - 03D Grach. Results and its discussion. The analysis of the obtained data showed that, according to the “Methodology for dosimetric control of industrial waste”, approved by the State Standard of the Russian Federation, the radiation background at the studied sites does not exceed the maximum allowable values. In these territories, no intervention measures are required to normalize the radiation situation.
