摘要: Evaluation of calculations and experimental evidence from 600-MeV proton irradiation indicating that cosmic-ray-induced radioactivity in detectors used to measure the diffuse gamma-ray background produces a significant counting rate energy region around 1 MeV. It is concluded these counts may be responsible for observed flattening photon spectrum at this energy.
