Appendix Figure 2. Leukocyte count based on exposure dose in patients exposed to radiation in Chernobyl. 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/mm³ to x10⁹ cells/L, multiply by 0.001.
