Радиоэкологическая оценка органоминеральных донных отложений озёр Обь-Чулымского междуречья (Васюганье)

Abstract

Various components of lake systems, territories on the territory of the Ob-Chulym interfluve (Vasyugane) were investigated for the content of natural and artificial radionuclides in accordance with the requirements of GOST. The aim of this work is to assess the radiation state of organic-mineral bottom sediments, taking into account their natural characteristics. It was found that the values of the total effective specific activity (Ac) for natural radionuclides for all lakes are below the norm (in accordance with the requirements of GOST). In terms of the content of artificial radionuclides, the study showed that the horizons in stratified deposits of sapropels of lakes do not correspond to radiation and hygienic standards, but for most lakes, the horizons of cesium accumulation are the upper 60 cm.
