Before the Fukushima Daiichi nuclear power plant accident, radionuclides like 90Sr released by atmospheric nuclear detonation tests and the Chernobyl accident have been transported worldwide in the environment and finally taken up by humans through various pathways. In this research, the health risks caused by the prolonged exposure to fallout 90Sr through food ingestion pathways were evaluated age-dependently for the reference Japanese since 1945 until 2010, using the mathematical model for evaluating global distribution of 90Sr with food ingestion considering the domestic and international food supply in Japan. The model estimates were compared with the monitoring data of 90Sr in Japanese total diet and 90Sr concentration in food to examine the model validity. The results of this evaluation would be useful for understanding the background situations without the Fukushima accident and give important knowledge for the radiological health risk assessment of this accident.
