Twenty Macaca mulatta monkeys were exposed to cobalt-60 gamma radiation at the rate of 1000 radminute for mid-thoracic doses of approximately 1307 rad to 10 monkeys and 2244 rad to the remaining 10 animals. The average intracranial pressure increased in both groups following exposure, but the response observed in the low-dose group was not so great as that elicited in the monkeys that were exposed to higher levels of irradiation. Hypotension developed in the majority of animals postirradiation, and the degree of response was greatest in the high-dose group of monkeys.
