VISUAL DISCRIMINATION PERFORMANCE IN THE MONKEY FOLLOWING A 2500-RAD PULSE OF MIXED GAMMA-NEUTRON RADIATION.

Abstract

Six monkeys, trained to perform a series of visual discriminations, were exposed to a 2500-rad pulse of gamma-neutron radiation. Performance decrements occurred during the first 2 hours postirradiation, with three of the monkeys exhibiting one or more severe decrements involving complete cessation of response. By 90 minutes postirradiation considerable recovery was exhibited. During later postirradiation testing sessions, the performance of four of the animals was comparable to the base-line level for a period of at least 120 hours. Of the two remaining animals one performed close to the lase-line level for 24 hours while the other seldom reached the base-line level of performance. (Author)
