DIN EN 62484:2016-06

Spectroscopy-based portal monitors have the ability to detect gamma and neutron radiation and identify gamma-emitting radionuclides that may be present in or on persons, vehicles or containers in a static or transient mode of operation. An alarm shall be triggered, when the signal of the system fulfills an alarm criterion or another preset condition, selectable by the operator of the radiation level or the identification result. The measurement is carried out, while the object is passing the detection area or is in a static mode in the detection area. This standard specifies the operational and performance requirements for spectroscopy-based portal monitors, used to detect and identify the illicit trade in radioactive substances. The operational requirements established by this standard include radiation detection and gamma-emitting radionuclide identification, and those requirements associated with the expected electrical, mechanical, and environmental conditions when a portal monitor is deployed. The object of this standard is to establish performance requirements, to give examples of acceptable test methods and to specify general characteristics, general test conditions, radiation characteristics, electrical safety and environmental characteristics to determine if a portal monitor meets the requirements of this standard. Obtaining operating performance that meets or exceeds the specifications as stated in this standard depends upon properly installing the monitor, establishing appropriate operating parameters, providing security for the monitor, maintaining calibration, implementing a suitable response testing and maintenance program, auditing compliance with quality requirements, and providing proper training for operating personnel. However, these aspects are not part of this standard. The responsible body is DKE/GUK 967.2 "Aktivitätsmessgeräte für den Strahlenschutz" of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
