Before the Fukushima Daiichi nuclear power plant accident, radionuclide like 137Cs released from atmospheric nuclear detonation tests and the Chernobyl accident has been transported worldwide in the environment and finally taken up by humans through various pathways. In this research, dietary intake of 137Cs and the health risks caused by prolonged radioactive global environment contamination were evaluated age-dependently for the reference Japanese since 1945 until 2010 by using the mathematical model for the evaluation of global distribution of 137Cs with food ingestion and domestic and international food supply model. The model estimates were compared with the monitoring data of 137Cs in Japanese total diet and 137Cs concentration in food as an attempt at validation. The results of this evaluation would be useful for understanding the background situations without the Fukushima accident and give important information for the radiological health risk assessment of the accident.
