Radiation protection instrumentation - Backpack-type radiation detector (BRD) for the detection of illicit trafficking of radioactive material

This Standard applies to backpack-type radiation detectors (BRDs) that are used for the detection of illicit trafficking of radioactive material. This standard establishes the operational and performance requirements for BRDs. BRDs are portable instruments designed to be worn during use. They may also be used as temporary area monitors in a stand-alone mode.

Instrumentation pour la radioprotection - Détecteur de rayonnement de type sac-à-dos (BRD) pour la détection du trafic illicite des matières radioactives

L'IEC 62694:2014 s'applique aux détecteurs de rayonnement de type sac à dos (BRD, backpack-type radiation detector) utilisés dans la détection du trafic illicite des matières radioactives. Cette norme établit les exigences de performances et d'essai associées aux mesures du rayonnement, ainsi que les conditions électriques, mécaniques et ambiantes prévues pendant l'utilisation.

Instrumenti za zaščito pred sevanjem - Nahrbtni detektor sevanja (BRD) za odkrivanje nezakonitega prometa z radioaktivnimi snovmi (IEC 62694:2014)

Ta standard se uporablja za nahrbtne detektorje sevanja (BRD), ki se uporabljajo za odkrivanje nezakonitega prometa z radioaktivnimi snovmi. Ta standard določa zahteve za delovanje za detektorje BRD. Detektorji BRD so prenosni instrumenti, ki so zasnovani tako, da se med uporabo nosijo. Uporabljajo se lahko tudi kot začasni območni senzorji v samostojnem načinu.

RADIATION PROTECTION INSTRUMENTATION – BACKPACK-TYPE
RADIATION DETECTOR (BRD) FOR THE DETECTION OF ILLICIT
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 62694 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 – BACKPACK-TYPE
RADIATION DETECTOR (BRD) FOR THE DETECTION OF ILLICIT
TRAFFICKING OF RADIOACTIVE MATERIAL
1 Scope

This International Standard applies to backpack-type radiation detectors (BRDs) that are used

for the detection of illicit trafficking of radioactive material. This standard establishes the

operational and performance requirements for BRDs. BRDs are portable instruments

designed to be worn during use. They may also be used as temporary area monitors in a

stand-alone mode.

BRDs detect gamma radiation and may include neutron detection and/or the identification of

gamma-ray emitting radionuclides. This standard establishes performance and testing

requirements associated with radiation measurements and the expected electrical,
mechanical, and environmental conditions while in use.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and

are indispensable for its application. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any
amendments) applies.
