CHRONIC WHOLE-BODY GAMMA RADIATION STRESS IN THE ALBINO RAT AND MOUSE.

Abstract

The recovery of the hematopoietic system following exposure of the whole animal to continuous and macrofractionated doses of gamma irradiation was studied. Following twelve weeks irradiation exposure, all animals were placed in the control environment and the recovery of the hematopoietic system evaluated. From this hematological data it is obvious that gamma irradiation at a ratio of 40 or 50 r per day for periods of twelve weeks, total doses of 4200 and 3360 r, does not do sufficient permanent damage to interfere with complete recovery of the peripheral blood picture. Exposure of 12 weeks dose rates in excess of 50 r per day would be necessary to produce sufficient damage to prevent recovery of the hematopoietic system.
