(Main)Radiation protection instrumentation - Alarming personal radiation devices (PRDs) for the detection of illicit trafficking of radioactive material
Radiation protection instrumentation - Alarming personal radiation devices (PRDs) for the detection of illicit trafficking of radioactive material
This standard applies to alarming radiation detection instruments that are pocket-sized, carried on the body and used to detect and indicate the presence and general magnitude of gamma radiation fields. Neutron detection may also be provided. Personal Radiation Devices (PRDs) alert the user to the presence of a source of radiation that is distinctly above the measured average local background radiation level. They are not intended to provide a measurement of the ambient or personal dose equivalent rate. This document does not apply to the ambient or personal dose equivalent rate meters which are covered in IEC 60846-1 or IEC 61526, respectively. If the manufacturer states that the PRD can be used for radiation protection purposes, compliance with IEC 60846-1 or IEC 61526 will be needed.
Instrumentation pour la radioprotection - Dispositifs individuels dalarme aux rayonnements pour la détection du trafic illicite des matières radioactives
IEC 62401:2017 décrire les critères fonctionnels et de conception ainsi que des méthodes d'essai pour évaluer les performances des PRD utilisés pour la détection de trafic illicite de matières radioactives (par exemple à la surveillance des frontières). Le présent document s'applique aux instruments de détection de rayonnement avec alarme qui sont portables en poche ou sur l'individu et qui sont utilisés pour détecter et signaler la présence et l'ordre de grandeur des champs de rayonnement gamma. La détection neutronique peut également être fournie. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) cohérence de la norme avec les nouvelles normes relatives à la détection du trafic illicite de matière radioactive (voir Introduction); b) modification de certaines exigences: c) création d'un essai de fonctionnalité uniforme pour tous les essais environnementaux, électromagnétiques et mécaniques, et d'une exigence relative au coefficient de variation de chaque relevé de moyenne nominal; d) référence à l'IEC 62706 pour les conditions d'essais environnementaux, électromagnétiques et mécaniques.
Instrumenti za zaščito pred sevanjem - Alarmni osebni detektorji sevanja za odkrivanje nedovoljenega prometa z radioaktivnimi snovmi (IEC 62401:2017)
Standard EN-IEC 62668-2 določa zahteve za izogibanje uporabi ponarejenih, recikliranih in goljufivih komponent, kadar te komponente niso kupljene pri proizvajalcu originalnih komponent (OCM) ali so kupljene zunaj franšiznih distribucijskih omrežij za uporabo v aeronavtični, obrambni in visokozmogljivostni (ADHP) panogi. Ta praksa se uporablja kot odstopanje samo, kadar ni razumnih ali praktičnih alternativ. Čeprav je bil pripravljen za aeronavtično, obrambno in visokozmogljivostno panogo, je mogoče ta dokument po ustrezni presoji uporabiti tudi za druge panoge, ki zahtevajo visoko zmogljivost in natančnost.
