Biological Effect of Microwave on the Nervous System

Abstract

This article presents an overview of the recent RT bioeffects literature dealing with the nervous system. Studies have evaluated the electroencephalography (EEG) of humans and laboratory animals during and after radiofrequency (RF) exposures. Exposure to high levels of RF energy can damage the structure and function of the nervous system. Much research has focused on the neurochemistry of the brain and the reported effects of RF exposure. Studies of individuals who are reported to be sensitive to electric and magnetic fields are discussed. The many exposure parameters such as frequency, orientation, modulation, power density, and duration of exposure make direct comparison of many experiments difficult. At high exposure power densities, thermal effects are prevalent and can lead to ad-verse consequences. At lower levels of exposure biological effects may still occur but thermal mechanisms are not ruled out. It is concluded that the diverse methods and experimental designs as well as lack of replication of many seemingly important studies prevents formation of definite conclusions concerning hazardous nervous system health effects from R-F exposure. The only firm conclusion that may be drawn is the potential for hazardous thermal consequences of high power RF exposure.
