Abstract : Fifteen male and fifteen female monkeys (Macaca mulatta) were trained by shock avoidance conditioning to work a visual discrimination problem. Each animal received a 4500-rad midline tissue dose of pulsed mixed gamma-neutron radiations; of each sex, five were head-shielded, five were trunk-shielded, and five were not shielded. The midline tissue dose behind the shield was less than 8 percent of midline tissue dose to the same point without the shield in place. Postirradiation performance was evaluated. Early performance decrement occurred after irradiation in all unshielded monkeys. Either trunk shielding or head shielding decreased the probability of performance decrement. However, among the shielded monkeys that did suffer an early decrement, the head-shielded subjects recovered sooner than the trunk-shielded subjects.
