having a sudden beginning--a sharp rise and a more or less short course would be noticed, The range of acute effects within this dosage include nausea, vomiting, diarrhea, itching and burning of the skin and mucous membranes, loss of hair, skin rurns, and a lowering, or depression, of various kinds of blood cells due to the hone marrow (the material within our bones which makes blood) being affected. At about 500 rads (depending upon individual response, health, ace, etc.) as mentioned hefore, 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 309 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, trouble with breathing, lack of balance and coordination, and convulsions, Death may be immediate or after a few hours, Should, somehow, a person survive these extreme dose s-mptoms, he would undoubtedly die from hemopoietic depression, where severe, disorders of the bone marrow, which produce hlood cells, anemia, and lack of resistance to infection. at the sublethal to lethal range, lead to internal hleeding, This effect can also he seen (94, p. 937) Many of the above types of disorders would ke brought about by direct exposure to the original explosion of the nuclear blast.
