DTI Studies of lxposure ofjabbits to S FEB 111981flectromadn*etic Pulsed Fields51

Dutch rabbits w~ere acutely exposed to electromagnetic pulsed (EMP) fields (pulse duration 0.4 ps, field strengths of 1-2 kV/cni and pulse repetition ratesin the range of 10 to 38 Hlz) for pcriods of up to twvo hours. The dependent variables investigated were petitobarbital-induced sleeping time and serum chenistry-(in-cluding serum triglycerides, creatine phosphokinase (CPK) isoenzymes, and sodium and potassium). Core temperature measured immediately pre-exposure and postexposure revealed no exposure-related alterations. Over the range offield strengths and pulse durations investigated no consistent, statistically sig-nificant alterations were found in the end-points investigated.
