Radiation protection instrumentation - Installed radiation portal monitors (RPMs) for the detection of illicit trafficking of radioactive and nuclear materials

IEC 62244:2019 defines the performance requirements of installed monitors used for the detection of gamma and neutron radiation emitters. These monitors are commonly known as radiation portal monitors or RPMs. They are used to monitor vehicles, cargo containers, people, or packages and are typically located at national and international border crossings. They may be used at any location where there is a need for this type of monitoring. This document establishes the general, radiological, climatic, mechanical, electric and electromagnetic and documentation requirements and associated test methods. This document does not apply to the performance of spectroscopy-based portal monitors covered in IEC 62484. This second edition cancels and replaces the first edition issued in 2006. This edition includes the following significant technical changes with respect to the previous edition:
a) making the standard consistent with the new standards for detection of illicit trafficking of radioactive material (see the Introduction);
b) creating unformed functionality test for all environmental, electromagnetic and mechanical tests and a requirement for the coefficient of variation of each nominal mean reading;
c) reference to IEC 62706 for the environmental, electromagnetic and mechanical test conditions;
d) adding information regarding climatic exposures.

Instrumentation pour la radioprotection - Portiques de détection des rayonnements (RPM) installés pour la détection du trafic illicite de matières radioactives et nucléaires

L'IEC 62244:2019 définit les exigences de performances des moniteurs installés, utilisés pour la détection des émetteurs de rayonnements gamma et neutroniques. Ces moniteurs sont le plus souvent utilisés comme portiques de détection des rayonnements (RPM). Ils sont utilisés pour surveiller des véhicules, des conteneurs de fret, des personnes ou des colis et ils sont le plus souvent situés aux frontières nationales et internationales. Ils peuvent être situés partout où ce type de surveillance est nécessaire. 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. Le présent document ne s'applique pas aux performances des moniteurs spectroscopiques pour portiques d'accès couverts par l'IEC 62484. Cette deuxième édition annule et remplace la première édition parue en 2006. 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) création d'un essai de fonctionnalité brut pour tous les essais environnementaux, électromagnétiques et mécaniques, et d'une exigence relative au coefficient de variation de chaque relevé de moyenne nominal;
c) référence à l'IEC 62706 pour les conditions d'essais environnementaux, électromagnétiques et mécaniques;
d) ajout d'informations concernant l'exposition aux conditions climatiques.

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 62244 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 issued in 2006. This edition

constitutes a technical revision.

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

edition:

a) making the standard consistent with the new standards for detection of illicit trafficking of

radioactive material (see the Introduction);

b) creating unformed functionality test for all environmental, electromagnetic and mechanical

tests and a requirement for the coefficient of variation of each nominal mean reading;

c) reference to IEC 62706 for the environmental, electromagnetic and mechanical test

conditions;
---------------------- Page: 7 ----------------------

d) adding information regarding climatic exposures.
The text of this International Standard is based on the following documents:
FDIS Report on voting
45B/929/FDIS 45B/930/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,

INTRODUCTION

Illicit and inadvertent movement of radioactive materials 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 of 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 instrumentation companies are developing and manufacturing radiation

instrumentation to assist in the detection of illicit movement of radioactive and special nuclear

materials. This type of instrumentation is widely used for security purposes at nuclear

facilities, border control checkpoints, and international seaports and airports.

However, to ensure that measurement results made at different locations are consistent it is

imperative that radiation instrumentation be designed to rigorous specifications based upon

agreed performance requirements stated in international standards. Several IEC standards

have been developed to address body-worn, hand-held and portal instruments, see Table 1.
