C. Dose Estimation from Residual and Fallout Radioactivity 2. A Simulated Neutron Activation Experiment

Review of Thirty Years Study of Hiroshima and Nagasaki Atomic Bomb Survivors I. DOSIMETRY

Abstract

Soil and various building materials from Hiroshima and Nagasaki were irradiated with neutrons and their induced radioactivities were determined. Based on these measurments, the dose rates and cumulative doses from the induced gamma-emitters in Hiroshima and Nagasaki were estimated. The cumulative dose to infinity at the hypocenter was 80 rads in Hiroshima and 30 rads in Nagasaki.
