Abstract
IEC 62484:2020 defines the performance requirements of installed monitors used for the detection and identification of gamma emitters and the detection of neutron radiation emitters. These monitors are commonly known as spectrometric radiation portal monitors or SRPMs. They are used to monitor vehicles, cargo containers, people, or packages and are typically used at national and international border crossings and ports of entry. SRPMs may be used at any location where there is a need for this type of monitoring.
This document establishes the general, radiological, climatic, mechanical, electric and electromagnetic and documentation requirements and associated test methods. A summary of the performance requirements and informative listing of environmental requirements from IEC 62706 is provided.
This edition includes the following significant technical changes with respect to the previous edition:
- title modified;
- making the standard consistent with the new standards for detection of illicit trafficking of radioactive material (see the Introduction);
- creating unformed functionality test for all environmental, electromagnetic and mechanical tests and a requirement for the coefficient of variation of each nominal mean reading;
- reference to IEC 62706 for the environmental, electromagnetic and mechanical test conditions;
- adding information regarding climatic exposures.
