Abstract : The 500 Rads test cell in building 500 at the Army Research Laboratory (ARL) contains a continuous x-ray source capable of producing lethal radiation levels within 15 seconds. Eight-foot thick walls of concrete are necessary but not sufficient to safeguard personnel. Operating procedures and engineered interlocks are required to ensure safety. This report documents the engineered interlock systems designed for safe operation. These solutions include emergency cutoff switches, warning lights, audible claxons, timing circuits, door interlocks and control circuitry. The electrical schematics, wiring diagrams and operational procedures are described.
