Effects of Exposure to Pulsed Microwaves (RADAR) on Central Nervous System Excitability in Laboratory Animals.

Abstract

A microwave bioeffects project was designed to develop reliable exposure methods and dose estimation procedures for use with laboratory animals to investigate potential effects on central nervous system (CNS) excitability. A resonating cavity exposure system, powered by a commercial 2.45 GHz pulsed magnetron, was developed and provided accurate control of the integral energy delivered multilaterally to the animal. A high performance anechoic chamber facility, powered by a 2.88 GHz radar transmitter, pulsed with high peak power, provided plane wave irradiation. A biodosimetry method, based on latency for microwave-induced seizure, was developed for use in both systems for indexing exposure levels, for validating biophysical dosimetry measurements and for investigating effects of field geometry.
