Abstract : Eighteen primates (Macaca mulatta) were trained to a Multiple Avoidance Program (MAP). Tasks requiring visual, auditory, and tactile discriminations were included in this program. Thirteen behavioral and three physiologic variables were analyzed for radiation effects at dose levels of 2,500, 3,750, and 5,000 rads up to 1 hour after irradiation. The analysis of all variables demonstrated a significant change across time (irradiation effect). When an analysis of variance was accomplished, no significant statistical differences were found between dose levels for any of the variables examined in this paper, possibly because of the small number of subjects per group. In two future reports the data examined in this experiment will be compared with subsequent data gathered on the identical variables and dose levels at differing dose rate and neutron-gamma ratios.
