La CEI 61526:2010 spécifie les caractéristiques générales, les procédures générales d'essai, les caractéristiques sous rayonnement ainsi que les caractéristiques électriques, mécaniques, de sécurité et environnementales. Les seules exigences spécifiées pour les systèmes de lecture associés sont celles qui concernent l'exactitude de la lecture de l'équivalent de dose individuel et du réglage des alarmes et les exigences qui concernent l'influence du lecteur sur le dosimètre. Cette nouvelle édition comprend les principales modifications techniques suivantes par rapport à la précédente édition:  - amélioration de la détermination de la constance de la réponse de dose et des fluctuations statistiques;  - suppression des classes d'appareils de mesure de l'équivalent de dose individuel en fonction de la conservation des informations;  - inclusion de catégories d'utilisation pour les dosimètres individuels.

Instrumenti za zaščito pred sevanjem - Merjenje osebnih ekvivalentnih doz Hp(10) in Hp(0,07) za rentgenska (X), gama, nevtronska in beta sevanja - Osebni dozimetri z neposrednim odbiranjem

Standard IEC 61526:2010 določa splošne lastnosti, splošne preskusne postopke, sevalne, električne, mehanske, varnostne in okoljske lastnosti. Edine zahteve za povezane sisteme odbiranja so zahteve, ki vplivajo na točnost odbiranja osebne ekvivalentne doze in nastavitev alarma, ter zahteve, ki se nanašajo na vplivanje bralnika na dozimetru. Ta nova izdaja glede na prejšnjo vključuje naslednje pomembne tehnične spremembe:
– boljše določanje stalnosti učinka doze in statističnih nihanj;
– odprava razredov merilnikov osebne ekvivalentne doze v zvezi s hrambo shranjenih informacij;
– vključitev kategorij uporabe osebnih dozimetrov.

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 61526 has been prepared by subcommittee 45B: Radiation protection instrumentation, of IEC technical committee 45: Nuclear instrumentation. This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with regard to the previous edition: – Inclusion of terms and definitions from ISO/IEC Guide 99:2007 (VIM:2008). – Full consistency with IEC/TR 62461:2006 “Radiation protection instrumentation – Deter-mination of uncertainty in measurement”.

– 8 – 61526 © IEC:2010 INTRODUCTION This International Standard applies to active, direct reading personal dose equivalent meters and monitors used for measuring the personal dose equivalents Hp(10) and Hp(0,07) for X, gamma, neutron and beta radiations.
For the personal dose equivalent Hp(10) or the personal dose equivalent rate ()10pH& and for X and gamma radiations, two minimum rated ranges for the photon energy are given. The first from 20 keV to 150 keV is for workplaces where low energy X-rays are used, e.g., in medical diagnostic, the second from 80 keV to 1,5 MeV is for workplaces where high energy X-rays and/or gamma sources are used, e.g., in industry. For neutron radiation the minimum rated range of neutron energy is from 0,025 eV (thermal neutrons) to 5 MeV. The rated ranges can be extended to all energies covered by the respective standards for reference radiation fields.
For the personal dose equivalent Hp(0,07) and for X and gamma radiations, a minimum rated range for the photon energy from 20 keV to 150 keV is given and for beta radiation, the minimal rated range is from 0,2 MeV to 0,8 MeV. The rated ranges can be extended to all energies covered by the respective standards for reference radiation fields. Examples of extended rated ranges are given in Annex C.
In some applications, for example, at a nuclear reactor installation where 6 MeV photon radi-ation is present, measurement of personal dose equivalent (rate) Hp(10) for photon energies up to 10 MeV should be required. In some other applications, measurement of Hp(10) down to 10 keV should be required. For personal dose equivalent meters, requirements for measuring the dose quantities Hp(10) and Hp(0,07) and for monitoring of the dose rate quantities ()10pH& and ()070p,H& are given. The measurement of these dose rate quantities is an option for personal dose equivalent meters. Establishments in some countries may wish to use this type of personal dose equivalent meter as the dosemeter to provide the dose of record by an approved dosimetry service. SIST EN 61526:2013

MEASUREMENT OF PERSONAL DOSE EQUIVALENTS Hp(10)
AND Hp(0,07) for X, GAMMA, NEUTRON AND BETA RADIATIONS –
DIRECT READING PERSONAL DOSE EQUIVALENT METERS
1 Scope and object This International Standard applies to personal dose equivalent meters with the following characteristics: a) They are worn on the trunk or the extremities of the body. b) They measure the personal dose equivalents Hp(10) and Hp(0,07) from external X and gamma, neutron and beta radiations, and may measure the personal dose equivalent rates ()10pH& and ()070p,H&. c) They have a digital indication. d) They may have alarm functions for the personal dose equivalents or personal dose equivalent rates. This standard is therefore applicable to the measurement of the following combinations of dose quantities (including the respective dose rates) and radiation
1) Hp(10) and Hp(0,07) from X and gamma radiations; 2) Hp(10) and Hp(0,07) from X, gamma and beta radiations; 3) Hp(10) from X and gamma radiations; 4) Hp(10) from neutron radiations; 5) Hp(10) from X, gamma and neutron radiations; 6) Hp(0,07) from X, gamma and beta radiations. NOTE 1 When reference is made in this standard to ”dose”, this is meant to indicate personal dose equivalent, unless otherwise stated.
NOTE 2 When reference is made in this standard to ”dosemeter”, this is meant to include all personal dose equivalent meters, unless otherwise stated.
This standard specifies requirements for the dosemeter and, if supplied, for its associated readout system.
This standard specifies, for the dosemeters described above, general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and envi-ronmental characteristics. The only requirements specified for associated readout systems are those which affect its accuracy of readout of the personal dose equivalent and alarm settings and those which concern the influence of the reader on the dosemeter. This standard also specifies in Annex C usage categories with respect to different measuring capabilities. This standard does not cover special requirements for accident or emergency dosimetry although the dosemeters may be used for this purpose. The standard does not apply to dosemeters used for measurement of pulsed radiation, such as radiation emanating from most medical diagnostic X-ray facilities, linear accelerators or similar equipment.
