Lifetime Attributable Risk (LAR) of cancer induced by radiation exposures is one of the important factors for deciding about radiological protection measures or protective actions for nuclear emergency preparedness and response. In Japan, while a model for estimating LAR for the Japanese population has been developed based on epidemiological data from A-bomb survivors, a flexible projection code implementing this model needs to be developed. This study investigated the existing codes to contribute to the development of the projection code. Based on these investigations, we compared their LAR calculation results, and explored the cause of their differences.
