Abstract
This paper reports on the results of radiation monitoring of bottom sediments in Yenisei Gulf for the period from 1995 to 2016. Clear positive trends in changing the radiation situation have been established. The obtained results showed that the radiocesium activity decreased by half not only in the surface layer but also in different horizons within the bottom sediments. The avalanche sedimentation rates ranging from 3.2 to 5.9 mm per year were determined. To estimate the sedimentation rates in the geochemical barrier zone, an alternate technique was proposed.
