Standard [WITHDRAWN] 2013-04
This International Standard applies to hand-held instruments used for the detection and localization of radioactive photon emitting materials. These instruments are highly sensitive meaning that they are designed to detect slight variations in the range of usual photon background caused mainly by illicit trafficking or inadvertent movement of radioactive material. This high sensitivity allows the scanning of larger volume items such as vehicles or containers. The instruments may also be used in fixed or temporarily fixed unattended mode to monitor check points or critical areas. Compliance with specifications that meets or exceeds the requirements stated in this standard depends upon properly establishing appropriate operating parameters, maintaining calibration, implementing a suitable response testing and maintenance program, providing proper training for operating personnel and developing operating procedures that address the instrument limitations and capabilities. These aspects are not covered by this standard, however. The responsible committee is GUK 967.2 "Aktivitätsmessgeräte für den Strahlenschutz" ("Activity meters for radiation protection") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE, Joint Committee with the Radiology Standards Committee (NAR) at DIN.
