DEVELOPMENT OF RAD HAZ SUIT AND RF MEASURING TECHNIQUES

Abstract

The hazardous RF environmental areas on ships and at shore installations have development of protective devices for personnel. In the process of producing a prototype RAD HAZ suit, low and high power rf facilities, measurement procedured, and new techniques for conductivity measurements and insertion loss calculations were developed. The latter enabled attenuation measurements to be made in the near field of receiving antennas. The silverized nylon material used in the suit withstood laundering dry cleaning, weathering, abrasion and open sea environments without degradation of rf attenuation properties. The suit provided a minimum of 25db attenuation for low-power fields at 5.2kmc (minimum of 30db at 425Mc) and better than 20db for high-power fields (BMEWS frequency, 200mw/sq. cm power density). Although the resistance of the material to salt spray and arcover was poor, this problem will be overcome by the use of a coating and over-garment.
