Radiation protection instrumentation - Spectroscopy-based portal monitors used for the detection and identification of illicit trafficking of radioactive material

This standard specifies the operational and performance requirements for spectroscopy-based portal monitors used for the detection and identification of illicit trafficking of radioactive material.  Spectroscopy-based portal monitors have the ability to detect gamma and neutron radiation and identify gamma-emitting radionuclides that may be present in or on persons, vehicles, containers, or packages in a static or transient mode of operation.
Operational requirements established by this standard include radiation detection and gamma-emitting radionuclide identification, and those requirements associated with the expected electrical, mechanical, and environmental conditions when a portal monitor is deployed.

Instrumentation pour la radioprotection - Moniteurs spectroscopiques pour portiques d'accès utilisés pour la détection et l'identification du trafic illicite des matières radioactives

La CEI 62484:2010 spécifie les exigences de fonctionnement et de performances des moniteurs spectroscopiques de portiques d'accès utilisés pour la détection et l'identification du trafic illicite des matières radioactives. Les moniteurs spectroscopiques de portiques d'accès ont la capacité de détecter des rayonnements gamma et neutroniques et d'identifier des radionucléides émettant un rayonnement gamma pouvant être présents dans ou sur des personnes, des véhicules, des conteneurs ou des colis dans un mode de fonctionnement statique ou en transit. Détermine des exigences de performances et donne des exemples de méthodes d'essai acceptables, spécifie des caractéristiques générales, des conditions d'essai générales, des caractéristiques de rayonnement, des caractéristiques de sécurité électrique et environnementales, afin de déterminer si un moniteur pour portique d'accès satisfait aux exigences de la présente norme.

Ta standard določa operativne zahteve in zahteve za delovanje za spektroskopsko vgrajene monitorje sevanja za odkrivanje in identifikacijo ilegalnega prometa z radioaktivnim materialom.  Spektroskopski vgrajeni monitorji sevanja zaznavajo sevanje gama žarkov in nevtronov ter prepoznavajo radionuklide, ki sevajo gama žarke ter so lahko prisotni v osebah, vozilih, kontejnerjih ali paketih oziroma na njih, v statičnem ali prehodnem načinu delovanja.
Zahteve za delovanje, ki jih opredeljuje ta standard, vključujejo zaznavanje sevanja in prepoznavanje radionuklidov, ki sevajo gama žarke, ter zahteve, povezane s pričakovanimi električnimi, mehanskimi in okoljskimi pogoji uvedbe monitorja sevanja.

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.

The text of this standard is based on the following documents:

RADIATION PROTECTION INSTRUMENTATION –
SPECTROSCOPY-BASED PORTAL MONITORS USED
FOR THE DETECTION AND IDENTIFICATION OF ILLICIT
TRAFFICKING OF RADIOACTIVE MATERIAL
1 Scope and object

This International Standard specifies the operational and performance requirements for

spectroscopy-based portal monitors used for the detection and identification of illicit trafficking

of radioactive material. Spectroscopy-based portal monitors have the ability to detect gamma

and neutron radiation and identify gamma-emitting radionuclides that may be present in or on

persons, vehicles, containers, or packages in a static or transient mode of operation.

Operational requirements established by this standard include radiation detection and

gamma-emitting radionuclide identification, and those requirements associated with the

expected electrical, mechanical, and environmental conditions when a portal monitor is

deployed.

The object of this standard is to establish performance requirements and to give examples of

acceptable test methods, and to specify general characteristics, general test conditions,

radiation characteristics, electrical safety, and environmental characteristics to determine if a

portal monitor meets the requirements of this standard.

Special applications, which may include a monitor’s operation under weather conditions or for

detection needs not addressed by this standard, shall require additional testing.

Obtaining operating performance that meets or exceeds the specifications as stated in this

standard depends upon properly installing the monitor, establishing appropriate operating

parameters, providing security for the monitor, maintaining calibration, implementing a

suitable response testing and maintenance program, auditing compliance with quality

requirements, and providing proper training for operating personnel.
