ABSTRACT (Cantinue on reverse side if neceseary and identify by block number) The data presented are a compilation of al] reported initial gamma measurements ade by the Department of Defense and other agenices, from Operation Sandstone (1948) hrough Operation Fish Bow] (1962). Where neutron data are available, the gamma easurements are corrected for the direct effect of the neutrons on the detector as ell as on the detector's environment. Shield attenuation of the gamma dose was aken into account. Gamma-dose-times-distance-squared, versus distance for shot onditions, is graphically presented.
