Primate Physical Acitivity Following Exposure to a Single 2000-Rad Pulsed Dose of Mixed Gamma-Neutron Radiation.
Abstract
Twelve male rhesus monkeys (Macaca mulatta) were trained to perform one of the following tasks: discrete trial, cued avoidance; shock motivated physical activity; or a combined cued avoidance-physical activity task. All tests were conducted in a primate physical activity wheel developed at the AFRRI. The animals were exposed to a single 2000-rad pulsed dose of mixed neutron-gamma radiation. All animals performing the physical activity task experienced periods of early transient incapacitation within the first seven minutes of postirradiation testing. Only one of the animals performing the cued avoidance task experienced an early transient incapacitation. The animals performing the combined task experienced periods of early transient incapacitation on the physical activity task but not on the cued avoidance task. The recovery period performance level of each of the animals performing the physical acitvity task was also significantly lower than the performance of any animal performing the cued avoidance task.
