Accumulation and retention of 137Cs by the common gogy, Acanthogobius flavimanus from environmental water and were and food were investigated in order to obtain quantitative information on the food chain transfer of the nuclide in coastal sea enveronment. It was found that the accumulation of 137Cs by the fish from water and food showed a gradual increasing tendency during the experimental period and required long period to reach an equilibrium level. Using a single exponential model, it was estimated that the accumulation of 137Cs by the fish required more than 90 days to reache equilibrium state. From the experimental results, it was suggested that the relative contribution of food in the accumulation of 137Cs by the fish was comparatively higher in comparison with direct absorption.
