Abstract : To determine the temperature response of the brain to radiation, thermistor temperature sensing probes were implanted into thalamic and cortical areas of eight monkeys and the arch of the aorta. After securing base-line temperature recordings, the monkeys were exposed to 2500 rads whole-body pulsed mixed gamma-neutron radiation in the AFRRI-TRIGA reactor. Temperature at all measured sites generally dropped briefly immediately after the pulse, then rose and stayed elevated 1-2C for the remainder of the 3-1/2-hour observation period. There did not appear to be any regional differences in brain temperature response, and brain temperature followed core (aortic) temperature changes.
