A RADIOFREQUENCY RADIATION EXPOSURE APPARATUS

Abstract

A radiofrequency radiation exposure apparatus was developed and placed into operation at the USAF School of Aerospace Medicine. The rectangular coaxial device has dimensions of 4 3/4 ft. by 9 1/4 ft. by 30 ft., with a 6-ft.- wide center conductor. It is powered by a 50-kwp. transmitter and operates in a pulsed mode at frequencies of 10.5, 19.27, and 26.6 MHz. Up to 12 animals (Macaca mulatta) can be exposed simultaneously to uniform fields ranging in power density from 0.05 to 0.2 w./sq cm. The instrumentation system, consisting of portable E- and H-field probes and fixed E-field probes, was developed and calibrated by the National Bureau of Standards. Details of the system design, checkout, and operation are presented.
