| Research Abstract |
The geographical distribution of mortality risk due to solid tumors among A-bomb survivors in Hiroshima was statistically estimated through a cohort analysis. The resultant contour map suggests that the region west to the hypocenter has a higher risk compared to other areas, which suggested the effect of additional exposure due to black rain. Relationship between damage situations due to A-bomb and degree of anxiety about their own health or their offspring were analyzed statistically. A gene that was found with specifically high frequency among MDS patients living near Semipalatinsk nuclear test site and A-bomb survivors was identified. In order to evaluate indirect dose of radiation among A-bomb survivors, dose ofβ-ray due to radiation fallout was estimated.
