Radiation-induced cancer is one of the key issues in a consequence analysis on a Nuclear Power Plant accident. U. S. Nuclear Regulatory Commission (USNRC) developed the estimation model of those risks for the use of accident consequence analysis in 1980s and 1990s. This model is still used as a leading model in this field. In this paper, we aimed to explore the differences between the results of risk prediction from the model of USNRC and those from a latest model. To achieve this aim, radiation-induced cancer risks were projected based on the Japanese population statistics using the models developed by USNRC and the latest model, which was developed by U. S. Environmental Protection Agency (USEPA). As compared to the model of USEPA, the lifetime attributable risks of all cancers projected by the model of USNRC were about 30% higher for male and about 35% lower for female in both morbidity and mortality. When the sex-averaged values were compared between them, the difference is within 10%.
