Abstract. Many studies emphasised influences of microwaves on the behavior of exposed animals. Various kinds of effects on central nervous activity have been reported for a wide range of microwave frequencies and of exposure levels. Excepting the well-known effects due to high-level exposures, present data are not conclusive concerning the relation between exposure level and specific effects. Our experiment searched for any possible effect on behavior and central nervous activity of mice exposed to low-level microwaves. Ten male Swiss mice were exposed 8 h/day, 5 days per week for 13 weeks to a 400 MHz microwave field of 1 mW/cm2 power density. The behavior of both exposed and control mice were examined by a battery of three behavioral tests applied every 15 days. The applied tests revealed some behavioral effects suggesting a reduction of the investigative potential of animals during the entire exposure period and, also, some phasic changes in time of their exploratory activity.
