Radiation protection instrumentation - Vehicle-mounted mobile systems for the detection of illicit trafficking of radioactive materials
This document applies to vehicle-mounted mobile systems (also known as mobile systems or mobile 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 rapid screening of large areas. These vehicle-mounted mobile systems consist of one or more radiation detectors mounted in a vehicle, e.g., car or van, which travels predominantly on public roads.

Instrumentation pour la radioprotection - Systèmes mobiles montés sur véhicules pour la détection du trafic illicite des matières radioactives
IEC 63121:2020 s'applique aux systèmes mobiles montés sur véhicules (également connus sous le nom de systèmes mobiles ou moniteurs mobiles) qui sont utilisés pour la détection du trafic illicite des matières radioactives; ces instruments peuvent également être utilisés pour la protection d'événements publics majeurs et pour le contrôle rapide de zones étendues. Ces systèmes mobiles montés sur véhicules comprennent un ou plusieurs détecteurs de rayonnement installés dans un véhicule (automobile ou fourgon, par exemple) qui se déplace principalement sur la voie publique. Le présent document ne s'applique pas aux systèmes de détection montés sur d'autres types de véhicules (avions, hélicoptères, trains ou bateaux, par exemple). Les systèmes de détection montés sur véhicules couverts par le présent document sont conçus pour détecter les sources radioactives alors que le véhicule est en mouvement. Ils peuvent également être utilisés comme des moniteurs fixes qui examinent des objets fixes ou en mouvement. Les systèmes mobiles montés sur véhicules détectent les rayonnements gamma, et peuvent inclure la détection neutronique et/ou l'identification de radionucléides émetteurs de rayons gamma. L'objet du présent document est de définir les exigences minimales relatives aux systèmes mobiles montés sur véhicules destinés à la détection de matières radioactives. Le présent document établit les exigences générales, radiologiques, climatiques, mécaniques, électriques et électromagnétiques, ainsi que les exigences de documentation et les méthodes d'essai associées.
Instrumenti za zaščito pred sevanjem - Vozila z vgrajenimi mobilnimi sistemi za odkrivanje nedovoljene trgovine z radioaktivnimi snovmi (IEC 63121:2020)
Ta dokument se uporablja za vozila z vgrajenimi mobilnimi sistemi (imenovana tudi mobilni sistemi ali mobilni monitorji), ki se uporabljajo za odkrivanje nedovoljene trgovine z radioaktivnimi snovmi; ti instrumenti se lahko uporabljajo tudi za zaščito večjih javnih dogodkov in hitro pregledovanje velikih območij. Vozila z vgrajenimi mobilnimi sistemi so sestavljena iz enega ali več detektorjev sevanja, nameščenih v vozilu (npr. avtomobilu ali kombiju), ki vozi pretežno po javnih cestah.
