UNE-EN IEC 63121:2021

This document applies to vehicle-mounted mobile systems (also known as mobile systems ormobile monitors) that are used for the detection of illicit trafficking of radioactive materials;these instruments may also be used for protection of major public events and for rapidscreening of large areas. These vehicle-mounted mobile systems consist of one or moreradiation detectors mounted in a vehicle, e.g., car or van, which travels predominantly onpublic roads. This document does not apply to detection systems mounted in other types ofvehicles, e.g., planes, helicopters, trains, or boats. Vehicle-mounted detection systemscovered by this document are designed to detect radioactive sources while the vehicle is inmotion. They may also be used as stationary monitors that scan stationary or moving objects.Vehicle-mounted mobile systems detect gamma radiation and may include neutron detectionand/or identification of gamma-ray emitting radionuclides.The purpose of this document is to set minimum requirements for vehicle-mounted mobilesystems for the detection of radioactive material. This document establishes general,radiological, climatic, mechanical, electric and electromagnetic, and documentationrequirements, and the associated test methods.
