Abstract
Efficiency of the transfer of gamma-emitting radionuclides in food chains including macrophytes, zoobenthos, fish bentho- and ichthyophages was estimated at the radiation-polluted region of the Enisey river. Essential differences in the efficiency of the transfer of natural and technogenic radionuclides between the components of different trophic levels were revealed. Substantial species-related differences in the accumulation of radionuclides in ichthyophage fish from food were revealed.
