| Research Abstract |
It is well known that radiation exposure is a cancer risk factor in terms of mortality, and assessing the risk is an important problem. The effect of radiation exposure on health status has been evaluated according to direct dose of radiation exposure. However, amount of radiation exposure among atomic bomb survivors was not actual measurement, but estimated based on physical calculations in dosimetry reconstruction. Other exposures, such as residual radioactivity, have not been evaluated in the current dosimetry systems. This implies that risk for all exposures combined has not been fully evaluated. In our study, developed a statistical method to visualize risk of cancer mortality and reported on circular asymmetry of the geographical distribution of solid cancer mortality risk. The high risk region was covered by Uda's area of Black Rain. This similarity suggests that Black Rain is a possible risk factor contributing to the geographical distribution of solid cancer mortality.
