32、cope and object The scope of this International Standard is to define the performance of installed monitors used for the detection of gamma and neutron radiation emitters contained in objects/ containers or vehicles, general characteristics, mechanical characteristics, environmental requirements, te

33、st procedures and documentation. This standard is applicable to installed monitors designed to detect special nuclear and other radioactive materials by their emitted gamma and/or neutron radiation. They are used to monitor vehicles, cargo containers, people, or packages and are typically located at

34、 national and international borders, but may be used at any location where there is a need for this type of monitoring. This standard does not apply to hand-held monitors. Information regarding the detection of special nuclear material (SNM) is contained in Annex A. This standard provides the purcha

35、ser with information that may be used to determine the performance of the monitor in detecting the presence of radioactive sources. This standard does not provide the data needed to determine the performance of the monitor in measuring the quantity of the radioactive material. In this standard, the

36、term radioactive material includes both special nuclear and radioactive material unless otherwise specifically noted. The radioactive material may be transported by vehicle, carried by person, or concealed in a cargo container or in a package moved by conveyor belt, such as international mail parcel

37、s. Conformance with the requirements of this standard does not guarantee that a radioactive source will always be discovered. The selection of the location and the configuration of the monitoring system on each site needs to be optimised to achieve the best performance, however, this is outside the

38、scope of this standard. 2 Normative references The following referenced documents are relevant to the application of this document. For dated references, only the edition cited applies.
