Abstract : Weight losses of the spleen and thymus of LAf1 mice exposed to initial gamma radiation at varying distances from the atomic weapons used in Dog, Easy, and George Shots were determined. These changes were compared with weight losses of the spleen and thymus of LAf1 animals exposed to various doses of 230-KVP X radiation in the control study. Significant variations in the slopes of the regression lines, fitted to the control study data and to the data of each of the three field tests, could not be demonstrated. The biological data indicated a mean free path for the initial gamma radiation in substantial agreement with physical values. Hence, it was felt that scaling biological data for all three field tests to an arbitrarily selected weapon yield and accompanying gamma ray flux was justified.
