In a behavioral study designed to detect the most immediate reaction of the intact nervous system to ionizing radiation, rats were exposed while asleep to X rays (250 kvp), and measurements of behavioral arousal and heart rate were made to indicate activation of the central nervous system. A transitory behavioral arousal was exhibited within 12 seconds at an exposure rate of 0.25 r/second.At a higher dose rate of 1.9 r/second this initial reaction increased in scope and by 30 seconds included sub-cortical activation as well, as indicated by a heart rate response.These reactions depended upon the rate of exposure and not upon the total dose. In blinded animals, exposure at the high intensity evoked both the behavioral arousal and the heart rate response. This indicates that CNS activation cannot be attributed to the direct effect of radiation on the visual receptor system. Although radiation may act as a stimulus to the CNS through other sensory systems it was also suggested that the nervous system itself is directly sensitive to ionizing radiation.

“…Hence it should not be surprising to find immediate effects upon the electroencephalogram (EEG) or an inhibitory effect upon conditioned responses under certain conditions. Some of the "depressions" of cortical EEG activity reported by Russian investigators resemble the pattern of low voltage, fast activity which accompanies arousal (Livanov, 1962;Tsypin & Grigor'ev, 1960).…”

Extremely low doses of ionizing radiation operate as complex stimuli with both cue and aversive properties. Recent studies have demonstrated that effects can be obtained with total doses of less than 1 roentgen. This fact may explain some of the controversies concerning radiosensitivity of mammals and the conflicting results obtained in behavioral and electroencephalographic tests for effects of radiation exposure recently reviewed in this journal.
