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 (IEC 62327:2017)

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)

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).

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62327 has been prepared by subcommittee 45B: Radiation

protection instrumentation, of IEC technical committee 45: Nuclear instrumentation.

This second edition cancels and replaces the first edition of IEC 62327, issued in 2006. It

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) addition of detailed methods of test;
b) revised identification test acceptance criteria for environmental tests;
c) changed format to match SC 45B template.

INTRODUCTION

Illicit and inadvertent movement of radioactive materials in the form of radiation sources and

contaminated metallurgical scrap has become a problem of increasing importance.

Radioactive sources out of regulatory control, so-called “orphan sources”, have frequently

caused serious radiation exposures and widespread contamination. Although illicit trafficking

in nuclear and other radioactive materials is not a new phenomenon, concern about a nuclear

“black market” has increased in the last few years particularly in view of its terrorist potential.

In response to the technical policy of the International Atomic Energy Agency (IAEA), the

World Customs Organization (WCO) and the International Criminal Police Organization

(Interpol) related to the detection and identification of special nuclear materials and security

trends, nuclear in
