| Research Abstract |
Gamma-ray exposure from neutron-induced radionuclides in soil by Hiroshima and Nagasaki atomic bombings were estimated based on neutron fluence values on the ground obtained through the works developing the radiation dosimetry system, DSO2. Comparison of calculated exposure rates with measurements around the hypocenters several months after the bombings indicated an agreement in Hiroshima, while the calculated values were larger than measurements in Nagasaki. We began new efforts to reevaluate residual radiation taking into consideration the contribution of local fallout with so-called "black rain".
