DIN EN IEC 62484:2022-08: Radiation protection instrumentation - Spectrometric radiation portal monitors (SRPMs) used for the detection and identification of illicit trafficking of radioactive material (IEC 62484:2020); German version EN IEC 62484:2021

Spectrometric portal monitors can detect gamma and neutron radiation and identify gamma radionuclides that may be present in or on persons, vehicles or containers in static or transient modes of operation. An alarm shall be triggered when the system's signal meets an alarm criterion or other preset condition (selectable by the operator for radiation level or identification result). The measurement is made while the object is passing through the detection zone or is statically in the detection zone. DIN EN IEC 62484 (VDE 0493-3-5) specifies the operational and performance requirements for spectrometric portal monitors used for the detection and identification of illicit transport of radioactive materials. The operational requirements specified in this standard include the detection of radiation and the identification of gamma radionuclides, as well as requirements regarding the expected electrical, mechanical and environmental conditions under which a portal monitor is used. Achieving operating characteristics that meet or exceed the specifications listed in this standard depends on proper installation of the monitor, setting appropriate operating parameters, safety measures taken for the monitor, ensuring calibration, implementing an appropriate testing and maintenance program, verifying compliance with quality requirements, and providing appropriate training for operating personnel. However, these aspects are not part of this standard. This document supersedes DIN EN 62484:2016-06; VDE 0493-3-5:2016-06. Compared to DIN EN 62484 (VDE 0493-3-5):2016-06, the following changes have been made: (a) change of title; (b) harmonization of the standard with the more recent standards for the detection of unauthorized transported radioactive material (see newly included introduction); (c) updating and addition of normative references and bibliographical references; (d) revision of section 3 on terms and abbreviations; (e) introduction of an unformalized functional test for all environmental, electromagnetic and mechanical tests and a requirement concerning the coefficient of variation for each mean value of the readings; f) with regard to the environmental, electromagnetic and mechanical test conditions, reference to IEC 62706; g) revision and addition of the description of the requirements and test methods; h) inclusion of information concerning climatic stresses; i) revision of the outline; j) editorial revision.
