The tests were initiated within 2 min postirradiation and 1 or 24 hours postirradiation.

Activity test: the general tendency was for exposed animals to exhibit less activity than controls during most of the test period.
Swimming performance: all of the exposed groups exhibited a moderate reduction in swimming speed late in the test, after they had been swimming for a considerable distance with apparently normal proficiency.
Discrimination performance: it is evident that the animals were missing or ignoring presentations of the signal (a light) at the outset of testing after an irradiation at either dose rate. The effect was greater after irradiation at the higher rate and was related to the body temperatures.
The characteristics of the irradiation effects produced on the three behaviors were largely dissimilar. Only in the vigilance test the effect was apparently related in a direct manner to hyperthermia.
