Abstract : The effect of 4200 rads of pulsed gamma-neutron irradiation on the performance of a sequential behavioral task by unrestrained monkeys (Macaca mulatta) was investigated. Data are presented which demonstrate a significant decrease in accuracy and an increase in latency of response. Two types of pronounced behavioral decrements were noted within the 8 hours of postirradiation testing: incapacitation (failure to respond during a 2-minute test period accompanied by observed physical debility) which occurred within the first 1.5 hours, and nonperformance (failure to respond during a 2-minute test period despite apparent physical ability to do so) which occurred between 1.5 and 8 hours after irradiation.
