    1. Figure 1. Shown are approximate times for hematopoietic, gastrointestinal ( ), and central nervous system ( ) symptoms at different ranges of dose of whole-body radiation for exposed, living persons. Hematopoietic changes include development of lymphopenia, granulocytopenia, or thrombocytopenia. Gastrointestinal symptoms include headache, nausea, vomiting, or diarrhea. Cerebrovascular signs and symptoms include headache, impaired cognition, disorientation, ataxia, seizures, prostration, and hypotension. Note that the signs and symptoms of different organ systems significantly overlap at each radiation dose and that cerebrovascular symptoms do not appear until exposure to a high whole-body dose. The relative severity of signs and symptoms is measured on an arbitrary scale. Prepared from data in reference .

    2. Figure 2. A numeric degree of severity is assigned for the cutaneous, gastrointestinal ( ), neurovascular, and hematopoietic systems, as defined in Tables and . The highest degree of toxicity to an organ system indicates the physiologic “response category” (that is, 1, 2, 3, or 4). Modified with permission from reference .

    3. Appendix Figure 1. Shown are the absolute leukocyte count ( ), estimated organ dose ( ), areas of skin injury ( ), injury to oral cavity and gastrointestinal system ( ), and body position relative to the radioactive source ( ) as a function of time after the exposure. To convert cells/mm to ×10 cells/L, multiply by 0.001. Redrawn with permission from reference .

    4. Appendix Figure 2. Note the abortive rise (transient increase before the fall) in counts of leukocytes, which are primarily composed of granulocytes, in doses less than 5 Gy. Neutropenia may not occur for weeks, especially with lower exposures, and its duration may be prolonged. To convert cells/mm to ×10 cells/L, multiply by 0.001.
