[Cumulated biological effects of microwaves and their reflection in behavior, work capacity, growth of body mass and state of brain neurons].

Albino rats were exposed to 2375 mHz microwaves of 500 microW/cm2 for 169 h. At the time of exposure, the body mass growth diminished, the efficiency and vertical motor activity decreased in exposed animals in comparison with the controls. Three types of radiation-induced damages were found in the brain: chromatolysis, pyknosis, and ischemia. Different brain parts displayed different sensitivity depending on their location in relation to transverse sutures of the skull.
