The Effect оf Repeated Exposure to Complexly Organized Electromagnetic Radiation on the Rats Behavior in the “Open Field” Test

In experiments on Wistar rats, males and females, the effect of 3-fold (1 hour a day with an interval of three days) and multiple (8 weeks, 5 days a week, 2 hours a day) pulsed-modulated electromagnetic radiation on the tentative research reactions was studied, tested by the “open field” method. The animals were irradiated in an anechoic chamber in the zone of the formed wave of the microwave source (a block of 10 generators carrying frequencies from 1 to 4 GHz, the total pulse power density 300 microW/cm2, pulse duration 25 ms, sweep cycles 1–6 Hz, cycle turn-around time 30s). It has been showed that exposure to such parameters can cause a stress reaction and an impairment of long-term memory in some irradiated animals, and female rats were more sensitive to the action of microwaves, than males. This reaction was transient and 1.5–2 months after cessation of irradiation, the behavior of the animals was restored. However, there is a danger that with constant exposure to microwaves, which, for example, occurs in mobile users, such behavior deviations may become fixed and clinically significant.
