score Between 500 and 1,000 Yards. Wearly 100% fatalities may be expected, with deaths occuring at various tines within the first three weeks after detonation and devending ucen the degree and nature of exposure, The types of injuries sustained vould agnin vary widely, In practically all cases, ionizing radiation could be the primary cause of death, though in many instances it may not be, Between 1,000 and 1,500 Yards. The likelihood of fatal injury due to the effects of ionizing radiations would be greatly reduced, but the likelihood of serious injury by flash and flame remains high, It may be expected that fatalities in this area would total approximately 50; of all individuals vresent, Between 1,500 and 2,500 Yards, Tonizing radiation may be expected to cause many non-fatal injuries, but practically all fatalisies would be directly attributable to other factors. It is likely that approximately 154 of all people in the area would be killed, Between 2,500 and 3,000 Yards, Fatalities would be rare, probably 15 to 2% of all versons in the zone, Most of them would be due to thermal burns or to indirect effects of the blast.
