IRREPARABLE BIOLOGICAL DAMAGE AND ITS INFLUENCE ON REPAIR RATE
Technical Report
·
OSTI ID:4007829
Nine hundred female RF mice were given conditioning exposures of Co/sup 60/ gamma rays ranging from 0 to 2000 rads by the fractionation method. Following 90 days of repair and recuperation, all groups were exposed to 450 rads of Co/sup 60/ gamma rays semiweekly to death. Accumulated median lethal doses and their equivalent acute values were calculated and compared to predicted values based on 5% irreparable injury and a 7-day repair half time. It was observed that predictions were accurate to within 3% of actual equivalent acute values. Observations were in support of the theory that irreparable damage from Co/sup 60/ gamma rays is lethal bound, having little or no effect on the repair rate. (auth)
