The retention and excretion by black-fish Girella punctata, of 59Fe taken up from seawater or food organisms were observed by tracer experiment. The highest concentration factor was shown by the seaweed, Enteromorpha sp. among the prey and predator organisms. In the uptake route of food, the contamination mode of food and food species had effect on the retention ratio of radionuclide, showing that 59Fe assimilated in food was more difficult for the uptake than 59Fe solution fed with food, and

The distribution ratio of radioiron in the body organ showed large distribution in digestive tract regardless of up take route and contamination mode of food. GFC profile showed that the combining form of radioiron are same as in all organs.
