Effects of divided doses of x-ray on mortality and hematology of small and large domestic animals.

Abstract

An attempt was made to establish a correlation of systemic recovery with hematological recovery after x radiation exposure for the mouse, rabbit, sheep, and goat under uniform experimental conditions. By separating these animals into two broad groups, small and large animals, significant differences were demonstrated as to their LD/sub 50/30/, hematological recovery, and systemic recovery. Furthermore, a significant departure from the generally accepted exponential recovery after a radiation insult is shown for both small and large animals. The need for a more critical analysis of recovery at intervals well past the recovery half-time is indicated in evaluating rates of recovery. (auth)
