Abstract : This preliminary report summarizes the analysis effort performed to date on the Aerial Radiac System (ARS) to assure proper ARS operation following exposure to nuclear radiation. To facilitate the analysis effort, the ARS has been subdivided into several subcircuits. Each subcircuit will be analyzed and/or tested to assure proper performance following exposure to radiation at specification level. The ARS is used to measure ground dose radiation level (Rads/hr). The Power Supplies convert aircraft 28 volts dc to regulated +15 and -15 volts dc and -1000 volts dc. Gamma dose rate is measured by the Photomultiplier Tube and converted to a voltage level by a log amplifier. This voltage when scaled by EMAX in the subtractor circuit becomes the air dose level. The Ground Dose Computer provides the ground dose level by combining a signal proportional to the altitude as furnished by a radar altimeter with the air dose level signal. The ground dose level signal is displayed, recorded and/or can be telemetered. A self test feature is also provided.
