An Evaluation of Flashlights Exposed to Continuous-Wave and Pulsed 415-MHz Radiofrequency Radiation.

Abstract

An experiment was conducted in which flashlights were exposed to continuous-wave (CW) and pulsed (2-ms pulse width and 27 pulses/s) 415-MHz radiofrequency radiation (RFR); the objective was to determine if and under what RFR exposure conditions the flashlights would exhibit self-switching. THe impetus for this effort was provided by a possible RFR overexposure incident on September 14, 1983 at the Clear Air Force Station (AFS) ballistic missile early warning system (BMEWS) site. It was recorded that some personnel, within the exposure volume, noticed their flashlights neoning. In our study, each flashlight was irradiated in the E, H, and K orientations and in the far- and near-field radiation zones. The thresholds of incandescence and the electric field strength for bulb burnout were measured. Keywords include: AN/FPS-92 radar, Dosimetry, Flashlight, Incandescence threshold, and Radiofrequency radiation.
