TABLE 6 (continued) Time After Exposure Summary of Effects Resulting from Whole Body Exposure to Radiation Lethal Dose Median Lethal Dose 600 r hoo r Pallor. Petechiae. Diarrhea and nosebleeds. Fourth Rapid emaciation. Week Death (Mortality probably 50%). Moderate Dose 300 to 100 r Sore throat. Pallor. Petechise. Diarrhea. Moderate emaciation. (Recovery | likely unless complicated by poor previous health or superimposed injuries or infections ). The injury expectation with non-instantaneous delivery of radiation cannot be schematically quantitated with the data available. As total dosage is protracted, there undoubtedly will be a decrease in the incidence of the acute toxic phase mown as "radiation sickness". However, for radiation delivered over relatively short periods of time, such as one or two days, it probably is safe to assume that the hemorrhagic and systemic infection problems will remain almost the same as for instantaneous dosages: Various semi-quantitative statements are available, but these are based on opinion and no accurate data are available for critical study. The statements given by McLean in the Military Surgeon, which are substantially the same as those given by the Radiological Warfare pane22/ ere summarized here. This is done to provide a "feel" for the problem. 22/ Noyes, W.A., et al., Radiological Warfare Report on Panel of Radiological Werfere, 1948, TID 204, SECRET, Restricted Data. 80
