Interpretation of the radioactive background observed in the OSO-7 gamma-ray monitorApplication of a spallation activation calculation to the OSO-7 gamma-ray monitor background shows that major line features and about 30% of the continuum can be understood as activation of the central detector crystal by trapped protons. Weaker line features arise from activation of materials unshielded by the anticoincidence cup, while the remaining continuum and annihilation line would seem to come largely from electron-photon cascades originating in the spacecraft.
