Food chain model has been developed to evaluate the process of the transport andaccumulation of radionuclide in aquatic organism by radioactive materials entered into freshwaterenvironment from the nuclear accident. The model was composed of eight boxes to estimate theconcentrations of aquatic organism and it was based on the ordinary partial differential equations. Developed model was compared with concentrations of organism in lake which was measured fromthe Fukushima accident. Some results agreed well with measurements and the others showed a little discrepancy due to the coarse box size in the model and lack of the observations. However, the simulations generally agreed with measurements and the developed food chain model will be used to assess the dose which is affected human by ingestion of contaminated products in terrestrial and aquatic environment.
