Abstract : A unique 435-MHz radiofrequency radiation exposure facility--constructed at the Georgia Institute of Technology under U.S. Air Force sponsorship--has been operationally evaluated for conducting long-term animal studies. The exposure device is a 4-tier, 12-ft-diam,. circular, parallel-plate waveguide arrangement. Slotted-cylinder antennas feed the waveguide and generate a horizontally polarized field. An identical unpowered system is used for sham-exposure control. The facility consists of: the waveguides, located in separate rooms; and a suite of support rooms, for animal preparation, data collection, and cage washing. The facility can house 100 exposed rats and 100 sham-exposed rats. The triple purpose of this study has been to evaluate the system, integrate several subsystems, and train technologists in operating the system. All exposed and sham-exposed animals were anesthetized (Nembutal) and implanted with plastic cannulas in the aortic arch and exteriorized at the back of the neck. Blood was drawn, via the cannula, at weekly intervals; and ACTH, corticosterone, and prolactin were assayed.
