U.S. Army Commanders are responsible for minimizing the total risk to their soldiers. Timely and quantifiable information on potential risks will lead to better decisions. One of the many risks that may be encountered on the battlefield or in peacekeeping missions is exposure to ionizing radiation. Human senses cannot detect ionizing radiation; therefore, one must rely on specialized equipment to detect, identify and measure sources of ionizing radiation. Equipment used the U.S. Army to detect, identify and measure ionizing radiation is typically referred to as RADIAC (Radiation, Detection, Indication and Computation) equipment. A set of U.S. Army RADIAC equipment may have multiple probes for the detection of different types of radiation. Special attention is given in this report to the Army's AN/PDR-77 RADIAC set. The information from this paper is being used by the Army to develop technical guides, which will provide survey protocols for the detection and quantification of radiological sources and for prospective estimation of risks. In understanding the capabilities and limitations of their RADIAC equipment, Army Commanders will have near real-time information on which to base decisions concerning one of the many risks their soldiers may encounter.
