Abstract : Seven male monkeys trained to a visual discrimination task were exposed to a pulsed 15,000-rad midline tissue does of gamma-neutron radiation. Of these seven animals, five were unable to perform within 5 minutes postirradiation and remained in a state of total nonperformance until death. The two remaining animals experienced periods of severe performance decrement followed by a return of performance capability which approached the preirradiation value. This performance capability deteriorated rapidly at 58 and 88 minutes postirradiation in these two animals, after which time the subjects failed to perform until death. The median survival time for all animals was 1 hour and 18 minutes. (Author)
