The Features of the Stress-Reaction to Repetitive Nanosecond Microwave Pulses

The effect of nanosecond repetitive pulsed microwaves on the possibility of triggering a stress response of laboratory mice was investigated. The exposure was carried out every day once per a day during the 5 days' period (4000 pulses per session) with repetition rates of 8, 13, 16 and 22 pulses per second. The source of radiation was a laboratory pulse generator based on a magnetron MI-505 with a carrier frequency of 10 GHz, a pulse duration at half the power level of 100 ns, an output peak power of 180 kW, an electric field strength of 1.5 10

. It was found that repeated exposure alters the level of corticosterone in the blood serum. The effect depends on the frequency of repetition of microwave pulses. Possible mechanisms of the effect of radiation on the level of corticosterone are considered.
