produced by blast, flying debris and structural collapse. They would be similar to those resulting from ordinary high explosive raids of comparable destructive force and would cover a wide range of individual severity. Phose Peculisr to Atomic Attack, These injuries, which may be observed either alone or in combination with other listed immediately above, are caused by sxposure to lonizing radiations, In non-fatal cases, the general signa and symptoms of such injuries usually become apparent from three to 21 days after exposure, They include malaise, nausea, bloody diarrhea, prolonged blood clotting time, and reduced resistence to infection and disease, Administration of whole blood represents the principal form of effective treatment, Promptly administer- ed, it may be expected to save the lives of many "borderline" cases, Georgraphical Distribution of Casualties. In general, but with marked "spotiness" attributable to "chance shielding" and other factors, the nature and percentage of casualties would be directly dependent upon distance from the point of detonation. Overwall distribution estimates, based on distances from the center of impact, are ag follows: Within 500 Yards. be expected, Nearly 100% immediate fatalities may They would be due to exposure to ionizing radiation, blast, burns, structural collapse and numeroud other factors, TOS ARCHIVES
