having a sudden beginning--a sharp rise and a more or less short course would be noticed. The ranqe of acute effects within this dosage include nausea, vomiting, diarrhea, itching and burning of the skin and mucous membranes, skin hurns, and a lowering, or depression, due to the bone marrow loss of haix, | of various kinds of blood cells (the material within our bones which makes blood) ‘being affected. At about 500 rads as mentioned hefore, (depending upon individual response, health, age, etc.) more than 50 percent of the people exposed would be expected to die. As the amount of exposure increases, fewer neonle would be expected to live until at about the 800 rad level generally 100 percent of the exposed persons would be expected to die. Higher doses above 1,000 rads whole-hody irradiation would produce what is called "gastro-intestinal death." The radiation results in destroying the lining of the small intestine and causes nausea, vomiting and diarrhea, Death would occur within a few days or a week. Central nervous system death would occur at doses over 3,000 rads. This size of dose causes extreme excitability, lack of balance and coordination, trouble with breathing, and convulsions. Death may be immediate or after a few hours. Should, somehow, a person survive these extreme dose symptoms, he would undoubtedly die from hemopoietic depression, where severe disorders of the bone marrow, which produce hlood cells, lead to internal bleeding, anemia, and lack of resistance to infection. at the sublethal to lethal range, This effect can also he seen (94, p. 937) Many of the above types of disorders would ke brought ahout by direct exposure to the original explosion of the nuclear blast.
