| Outline of Final Research Achievements |
While there is a considerable number of studies on the relationship between the risk of disease or death and direct exposure from the atomic bomb in Hiroshima, the risk for indirect exposure caused by residual radioactivity has not yet been fully evaluated. One of the reasons is that risk assessments have utilized estimated radiation doses, but that it is difficult to estimate indirect exposure. To evaluate risks for other causes, including indirect radiation
exposure, as well as direct exposure, a statistical method is described here that evaluates risk with respect to individual location at the time of atomic bomb exposure instead of radiation dose. We modeled time varying effect of radiation exposure on health status and made an animation of risk map. Based on the animated risk map, we discussed possibilities of influence of indirect exposure on health status among atomic bomb survivors.
