The mathematical model was developed for evaluating a fallout 90Sr accumulation in Japanese bone through its dietary intake, and was validated by comparing the estimates of 90Sr concentration in bone with the observed. The mortality risk by the radiation-induced leukemia and bone cancer was evaluated based on the NUREG/CR4214 model. The main results obtained in this study under the limited assumptions are as follows: (1) The mathematical model was developed to relate 90Sr concentration in an environment with the mortality risk due to the radiation-induced leukemia and bone cancer through dietary intake of fallout 90Sr. (2) The leukemia mortality risk due to the fallout 90Sr is about one order larger than the bone cancer mortalit risk, and is evaluated to be larger than 10-6 for Japanese who were born before early 1970' (3) The leukemia mortality risk due to the fallout 90Sr is about 10% level in 1992 of the leukemia mortality risk expected by the benzene in ambient air.
