Radiation protection instrumentation - Installed radiation monitors for the detection of radioactive and special nuclear materials at national borders

The scope of this International Standard is to define the performance of installed monitors used for the detection of gamma and neutron radiation emitters contained in objects/ containers or vehicles, general characteristics, mechanical characteristics, environmental requirements, test procedures and documentation. This standard is applicable to installed monitors designed to detect special nuclear and other radioactive materials by their emitted gamma and/or neutron radiation. They are used to monitor vehicles, cargo containers, people, or packages and are typically located at national and international borders, but may be used at any location where there is a need for this type of monitoring. This standard does not apply to hand-held monitors. Information regarding the detection of special nuclear material (SNM) is contained in Annex A. This standard provides the purchaser with information that may be used to determine the performance of the monitor in detecting the presence of radioactive sources. This standard does not provide the data needed to determine the performance of the monitor in measuring the quantity of the radioactive material. In this standard, the term radioactive material includes both special nuclear and radioactive material unless otherwise specifically noted. The radioactive material may be transported by vehicle, carried by person, or concealed in a cargo container or in a package moved by conveyor belt, such as international mail parcels. Conformance with the requirements of this standard does not guarantee that a radioactive source will always be discovered. The selection of the location and the configuration of the monitoring system on each site needs to be optimised to achieve the best performance, however, this is outside the scope of this standard.

Instrumentation pour la radioprotection - Moniteurs de rayonnement installés pour la détection des matériaux nucléaires radioactifs et spéciaux aux frontières nationales

Définit les performances des moniteurs installés pour la détection des émetteurs de rayonnements gamma et neutronique contenus dans des objets/conteneurs ou des véhicules, des caractéristiques générales, des caractéristiques mécaniques, des exigences d'environnement, des procédures d'essai et de la documentation. Ces moniteurs sont utilisés pour surveiller des véhicules, des containers de cargo, des personnes ou des colis et ils sont le plus souvent situés aux frontières nationales et internationales, mais ils peuvent être situés partout où il y a un besoin de ce type de surveillance.

Oprema za zaščito pred sevanjem - Vgrajeni monitorji sevanja za odkrivanje radioaktivnih in posebnih nuklearnih materialov na državnih mejah

Namen tega mednarodnega standarda je opredeliti delovanje vgrajenih monitorjev, ki se uporabljajo za odkrivanje materialov, ki oddajajo sevanje gama in nevtronsko sevanje in se nahajajo v predmetih/zabojnikih ali vozilih, splošne značilnosti, mehanske značilnosti, okoljske zahteve, preskusne postopke in dokumentacijo. Ta standard velja za vgrajene monitorje, namenjene odkrivanju posebnih jedrskih in drugih radioaktivnih materialov, ki oddajajo sevanje gama in/ali nevtronsko sevanje. Uporabljajo se za nadzor vozil, tovornih zabojnikov, ljudi ali paketov in so praviloma nameščeni na nacionalnih in mednarodnih mejah, lahko pa se uporabljajo na vseh krajih, kjer obstaja potreba po tovrstnem nadzoru. Ta standard ne velja za ročne monitorje. Informacije v zvezi z odkrivanjem posebnega jedrskega materiala (SNM) so navedene v dodatku A. Ta standard kupcu zagotavlja informacije, ki se lahko uporabijo za ugotavljanje učinkovitosti monitorja pri odkrivanju prisotnosti radioaktivnih virov. Ta standard ne zagotavlja podatkov, potrebnih za ugotavljanje učinkovitosti monitorja pri merjenju količine radioaktivnega materiala. V tem standardu izraz radioaktivni material vključuje posebni jedrski in radioaktivni material, razen če ni posebej navedeno drugače. Radioaktivni material se lahko prevaža z vozilom, lahko ga pri sebi nosi človek, lahko pa se skrije v tovorni zabojnik ali paket, ki se premika po transportnem traku, na primer paket mednarodne pošte. Skladnost z zahtevami tega standarda ne zagotavlja, da bo radioaktivni vir vedno odkrit. Izbiro kraja in konfiguracije nadzornega sistema na vsakem mestu je treba optimizirati, da se doseže optimalni učinek, vendar pa je to zunaj okvira uporabe tega standarda.

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 and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

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 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 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
