CHAPTER & Examination of the data indicates the following conclusions: 1. Yor surface bursts with yields to 5 Mt, and for a. 4300-foot asstort, initia’ gamm radiation is of Little military Significance to wprotected persomnel es compared vite thermal and blast damage. 2. The amount of residual refiation exposure is a function ef the Sission yield. 3. The curves of initial gamma exposure versus distance obtained from Project 2.1 dsta vary from corresponding TH £3-200 curves. At long ranges, Project 2.1 date are below the predicted data, whereas st shorter ranges, the field data crosses over and the reverse is true. This variation between predicted end field date increases vith increasing . ST, Lovic ect pe EE ES
