Some time ago an FPS-35 Radar was constructed in the vicinity of the ADC ammunition area, alert hangar area and the main runway at Selfridge Air Force Base, Michigan. According to Chart 6-1 in AFM 32-6, which is used as a guide for determining RF Energy hazard areas, a hazard existed at Selfridge Air Force Base. The FPS-35 Radar was restricted to low power operation until the problem could be solved. Four types of tests were made to determine the actual hazard. GEEIA made field strength measurements in the ADC ammunition area and in the alert hangar area. An instrumented AIM-4C missile was flown near the radar antenna. The instrumented AIM-4C was also carried on a truck through all areas where a maxium hazard could exist. Also live squibs and blasting caps were placed, with leads extended, on a truck and driven throughout the area. All measurements indicated that standard airmunitions are safe however, the current recorded in the instrumented igniter during the flight test was about one-fourth of the no-fire current of a live igniter.
