Аннотация: Abstract: The studies of bottom sediments of the Yenisei River from 2006 to 2016 near the Mining and Chemical Combine (MCC) and at a distance of up to 250 km from it downriver revealed an increased content of the radionuclide 60Co (including radioactive microparticles) in the upper layers. The specific activity of 60Co in the riverПоказать полностьюfloodplain increased due to the extreme flood of 2006. The 137Cs/60Co ratio in the surface layers of bottom sediments after the flood varied from 0.2 to 1.0 and differed significantly from the 137Cs/60Co ratio (2.5–6.0) in the surface layers before the flood. The increased content of 60Co in the upper layers of bottom sediments can serve as a marker of the 2006 event for calculating the sedimentation rate and dating the input of radionuclides into bottom sediments. © 2022, Pleiades Publishing, Ltd.
