Description

With reference to the significance of a study of migration of radionuclides in a river basin, two research projects for the Yenisei River Basin were reviewed. The first one, the International Science and Technology Center Project no.748, provided a new data set on the source and the characteristics of radioactive contamination in the basin, including transuranic elements. The second one, that was conducted by the International Institute for Applied Systems Analysis, encompassed dose evaluation in various scenarios based on considerations of source conditions and a hydrodynamic transport model of suspended sediment in a flood event. These studies exemplified that the assessment of physiological influences due to any environmental contaminants requires following issues: considerations on various ''axes'' in geographical space and phenomena, the use of an adequately simplified'' mathematical model of their migration, and the adoption of ''easily recognizable endpoint'' to quantify the influences.
