Radiation protection instrumentation - Portable photon contamination meters and monitors (IEC 62363:2008, modified)

This International Standard is applicable to portable and transportable contamination meters and monitors designed for the direct measurement or the direct detection of surface contamination by photon radiation emitting radionuclides and which comprise at least: - a detection assembly (comprising counter tube, scintillation detector or semiconductor detector, etc.), which may be connected either rigidly or by means of a flexible cable or incorporated into a single assembly; - a measurement assembly. The standard is applicable to: - photon surface contamination meters; - photon surface contamination monitors. The standard is applicable to detection assemblies that are designed to measure photon contamination from radionuclides which emit photons with energy in excess of 5 keV. In particular, this standard should be used to assess the performance of assemblies used to demonstrate that material is free from surface contamination by photon emitting radionuclides. This standard is also applicable to special purpose assemblies and to assemblies specifically designed to provide limited spectroscopic information to the user. The object of this standard is to lay down standard requirements and to give examples of acceptable methods, and also to specify general characteristics, general test conditions, radiation characteristics, electrical safety, environmental characteristics, and the requirements of the identification certificate for photon contamination meters and monitors.

Instrumenti za zaščito pred sevanjem - Prenosni merilniki in monitorji fotonske kontaminacije (IEC 62363:2008, spremenjen)

Ta mednarodni standard velja za prenosne in premične merilnike in monitorje kontaminacije, načrtovane za neposredno merjenje ali neposredno zaznavanje površinske kontaminacije z radionuklidi, ki oddajajo fotonsko sevanje, in zajemajo vsaj: - sklop za zaznavanje (sestavljen iz merilne epruvete, scintilacijskega detektorja ali polprevodnega detektorja itd.), ki je lahko povezan togo ali z gibljivim kablom ali vgrajen v enotni sestav; - merilni sestav. Ta standard velja za: - merilnike fotonske kontaminacije površine; - monitorje fotonske kontaminacije površine. Standard velja za zaznavne sestave, načrtovane za merjenje fotonske kontaminacije iz nuklidov, ki oddajajo fotone z energijo nad 5 keV. Še posebno bi se ta standard moral uporabljati za ocenitev delovanja sestavov, uporabljenih za dokazovanje, da material ni površinsko kontaminiran z radionuklidi, ki oddajajo fotone. Ta standard prav tako velja za sestave za posebne namene in za sestave, načrtovane predvsem za zagotavljanje omejenih spektroskopskih informacij uporabniku. Cilj tega standarda je določiti zahteve standarda in podati primere sprejemljivih metod ter prav tako določiti splošne značilnosti, splošne preskusne pogoje, značilnosti sevanja, električno varnost, okoljske značilnosti in zahteve identifikacijskega certifikata za merilnike in monitorje fotonske kontaminacije.

RADIATION PROTECTION INSTRUMENTATION –
PORTABLE PHOTON CONTAMINATION METERS AND MONITORS


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 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 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 62363 has been prepared by subcommittee 45B: Radiation
protection instrumentation, of IEC technical committee 45: Nuclear instrumentation.
This standard should be regarded as a complementary standard to IEC 60325, which is
applicable to alpha and beta contamination monitoring assemblies.
The text of this standard is based on the following documents:
FDIS Report on voting
45B/579/FDIS 45B/590/RVD

Full information on the voting for the approval of this 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.

RADIATION PROTECTION INSTRUMENTATION –
PORTABLE PHOTON CONTAMINATION METERS AND MONITORS



1 Scope and object
This International Standard is applicable to portable and transportable contamination meters
and monitors designed for the direct measurement or the direct detection of surface
contamination by photon radiation emitting radionuclides and which comprise at least:
– a detection assembly (comprising counter tube, scintillation detector or semiconductor
detector, etc.), which may be connected either rigidly or by means of a flexible cable or
incorporated into a single assembly;
– a measurement assembly.
The standard is applicable to:
– photon surface contamination meters;
– photon surface contamination monitors.
The standard is applicable to detection assemblies that are designed to measure photon
contamination from radionuclides which emit photons with energy in excess of 5 keV. In
particular, this standard should be used to assess the performance of assemblies used to
demonstrate that material is free from surface contamination by photon emitting radionuclides.
This standard is also applicable to special purpose assemblies and to assemblies specifically
designed to provide limited spectroscopic information to the user.
NOTE These detection assemblies may be used to measure photon emissions from radionuclides that also emit
alpha and beta radiations, where the alpha and beta emissions may be shielded due to the nature of the
contamination. If shielding of the radioactive emissions occurs, then strictly speaking, the contamination is near to
rather than on the surface of the article being monitored.
The object of this standard is to lay down standard requirements and to give examples of
acceptable methods, and also to specify general characteristics, general test conditions,
radiation characteristics, electrical safety, environmental characteristics, and the requirements
of the identification certificate for photon contamination meters and monitors.
