Radiation protection instrumentation - Hand-held instruments for the detection and identification of radionuclides and for the estimation of ambient dose equivalent rate from photon radiation

This standard applies to hand-held instruments used to detect and identify radionuclides and radioactive material, to estimate ambient dose equivalent rate from photon radiation, and optionally, to detect neutron radiation. They are commonly known as radionuclide identification devices or RIDs. This standard does not cover laboratory type, high-resolution photon spectrometers, or instruments covered by IEC 60846-1 (Portable workplace and environmental meters and monitors), IEC 60846-2 (photon dose (rate) meters) or IEC 61005 (neutron dose equivalent (rate) meters).

Instrumentation pour la radioprotection – Instruments portables pour la détection et l'identification des radionucléides et pour l'estimation du débit d'équivalent de dose ambiant pour le rayonnement de photons

IEC 62327:2017 spécifie les caractéristiques générales, les procédures générales d'essai, les caractéristiques de rayonnement, ainsi que les caractéristiques électriques, mécaniques, de sécurité et d'environnement. Le présent document s'applique aux instruments portables utilisés pour la détection et l'identification des radionucléides et des matières radioactives, pour l'estimation du débit d'équivalent de dose ambiant des rayonnements de photons et, éventuellement, pour la détection des rayonnements de neutrons. Ces instruments sont communément appelés dispositifs d'identification des radionucléides ou RID. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - ajout de méthodes d'essai détaillées; - révision des critères d'acceptation des essais d'identification pour les essais d'environnement;

Instrumenti za zaščito pred sevanjem - Ročni instrumenti za odkrivanje in prepoznavanje radionuklidov in za prikaz stopnje ekvivalentne doze v prostoru zaradi fotonskega sevanja (IEC 62327:2017)

Ta standard se uporablja za ročne instrumente, ki se uporabljajo za odkrivanje in prepoznavanje radionuklidov in radioaktivnega materiala, za vrednotenje stopnje ekvivalentne doze v prostoru zaradi fotonskega sevanja ter izbirno za zaznavanje nevtronskega sevanja. Ti instrumenti so splošno znani kot naprave za prepoznavanje radionuklidov ali RID. Ta standard ne zajema laboratorijskih fotonskih spektrometrov z visoko ločljivostjo ali instrumentov, ki jih zajema standard IEC 60846-1 (prenosni in okoljski merilniki ter monitorji), IEC 60846-2 (merilniki fotonske doze) ali IEC 61005 (merilniki ekvivalentne nevtronske doze).
