Abstract:

The Primate Equilibrium Platform PEP was utilized in an experiment at White Sands Missile Range, N. Mex., to determine the behavioral effects of single versus multiple irradiations. Eight trained primates Macaca mulatta were exposed to a single 1,500-rad pulse, and their performance was compared with the responses of a second group of 8 comparably trained primates receiving three 500-rad pulses spaced 1 hour apart. The subjects receiving multiple 500-rad pulses performed without appreciable change throughout the 20-hour postirradiation observation period, whereas those receiving the single 1,500-rad dose exhibited varying degrees of performance decrement. It was concluded that fractionation of dose within the limits explored herein had a definite mediating effect upon primate response to irradiation. Author
