Abstract : Airfield lighting is complex in its requirements for lights of various intensities and colors. Some applications such as taxiway lights, information signs, and combat situations may be served by lights of relatively low intensity. They should meet criteria such as energy efficiency, little or no dependence upon batteries or generators, low maintenance, and rapid deployment. Lights powered with krypton-85 provide some of these advantages. This report summarizes an effort to develop krypton-85 powered airfield lighting. Light is produced when beta rays from krypton-85 excite a phosphor. Phosphors selected produced blue, red, and yellow-green light. Field testing of the lights was sufficiently encouraging to continue development in a follow-on effort. (Author)
