Radiation protection instrumentation - Spectrometric radiation portal monitors (SRPMs) used for the detection and identification of illicit trafficking of radioactive material (IEC 62484:2020)
This document defines the performance requirements of installed monitors used for the detection and identification of gamma emitters and the detection of neutron radiation emitters. These monitors are commonly known as spectrometric radiation portal monitors or SRPMs. They are used to monitor vehicles, cargo containers, people, or packages and are typically used at national and international border crossings and ports of entry. SRPMs may be used at any location where there is a need for this type of monitoring.

IEC 62484:2020 définit les exigences de performances des moniteurs installés, qui sont utilisés pour la détection et l'identification des émetteurs de rayonnements gamma et pour la détection des émetteurs de rayonnements neutroniques. Ces moniteurs sont souvent appelés portiques spectrométriques de détection des rayonnements ou SRPMs (Spectrometric Radiation Portal Monitors). Ils sont utilisés pour surveiller des véhicules, des conteneurs de fret, des personnes ou des colis et généralement employés aux frontières nationales et internationales, ainsi qu'aux ports d'entrée. Les SRPMs peuvent être utilisés à tous les emplacements, 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 Tableau 11 fournit un récapitulatif des exigences de performances. Une liste informative des exigences d'environnement de l'IEC 62706 est fournie.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- modification du titre;
- cohérence de la norme avec les nouvelles normes relatives à la détection du trafic illicite de matières radioactives (voir l'Introduction);
- 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;
- référence à l'IEC 62706 pour les conditions d'essais environnementaux, électromagnétiques et mécaniques;
- ajout d'informations concernant l'exposition aux conditions climatiques.

Ta dokument določa zahteve za delovanje nameščenih monitorjev, ki se uporabljajo za odkrivanje in identifikacijo sevalnikov gama žarkov ter zaznavanje nevtronskega sevanja. Ti monitorji so splošno znani kot spektrometrski portalni monitorji (SRPM). Uporabljajo se za nadzor vozil, zabojnikov za tovor, oseb ali paketov, običajno na državnih in mednarodnih mejnih prehodih ter vstopnih pristaniščih. Portalni monitorji se lahko uporabljajo na vseh lokacijah, kjer je potreben tak nadzor.

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 62484 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 62484 issued in 2010. This
edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) title modified;
b) making the standard consistent with the new standards for detection of illicit trafficking of
radioactive material (see the Introduction);
c) creating unformed functionality test for all environmental, electromagnetic and mechanical
tests and a requirement for the coefficient of variation of each nominal mean reading;
---------------------- Page: 11 ----------------------

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 s

TRAFFICKING OF RADIOACTIVE MATERIAL
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 62484 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 62484 issued in 2010. This
edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) title modified;
b) making the standard consistent with the new standards for detection of illicit trafficking of
radioactive material (see the Introduction);
c) creating unformed functionality test for all environmental, electromagnetic and mechanical
tests and a requirement for the coefficient of variation of each nominal mean reading;

d) reference to IEC 62706 for the environmental, electromagnetic and mechanical test
conditions;
e) adding information regarding climatic exposures.
The text of this International Standard is based on the following documents:
FDIS Report on voting
45B/969/FDIS 45B/971/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be

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.
