IEC 62387:2020 est disponible sous forme de IEC 62387:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 62387:2020 s’applique à toutes sortes de systèmes dosimétriques passifs utilisés pour la mesure de: - l’équivalent de dose individuel Hp(10) (pour le contrôle radiologique individuel du corps entier), - l’équivalent de dose individuel Hp(3) (pour le contrôle radiologique individuel des cristallins), - l’équivalent de dose individuel Hp(0,07) (pour le contrôle radiologique individuel de la peau du corps entier et de la peau locale et des extrémités), - l’équivalent de dose ambiant H*(10) (pour le contrôle radiologique du lieu de travail et de l'environnement), - l’équivalent de dose directionnel H'(3) (pour le contrôle radiologique du lieu de travail et de l'environnement), ou - l’équivalent de dose directionnel H’(0,07) (pour le contrôle radiologique du lieu de travail et de l'environnement). Le présent document s’applique aux systèmes dosimétriques qui mesurent les rayonnements photoniques et/ou bêta externes dans la plage de dose comprise entre 0,01 mSv et 10 Sv et dans les plages d’énergie données dans le Tableau 1. Toutes les valeurs d’énergie données sont des valeurs moyennes par rapport à la fluence. Les systèmes dosimétriques utilisent habituellement des dispositifs électroniques pour l’évaluation des données et sont donc souvent commandés par ordinateur.

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 62387 has been prepared by subcommittee 45B: Radiation
protection instrumentation, of IEC technical committee 45: Nuclear instrumentation.
This second edition cancels and replaces the first edition of IEC 62387 published in 2012.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• Modification of title.
• Addition of performance requirements for dosemeters to measure H'(3) for both photon
and beta radiation.

INTRODUCTION
A dosimetry system may consist of the following elements:
a) a passive device, referred to herein as a detector, which, after the exposure to radiation,
stores a signal for use in measuring one or more quantities of the incident radiation field;
b) a “dosemeter”, that incorporates some means of identification and contains one or more
detectors and may contain electronic components, e.g. for the readout (e.g., in a direct ion
storage (DIS) dosemeter);
c) a “reader” which is used to readout the stored information (signal) from the detector, in
order to determine the radiation dose;
d) a “computer” with appropriate “software” to control the reader, store the signals
transmitted from the reader, calculate, display and store the evaluated dose in the form of
an electronic file or paper copy;
e) “additional equipment” and documented procedures (instruction manual) for performing
associated processes such as deleting stored dose information, cleaning dosemeters, or
those needed to ensure the effectiveness of the whole system.

RADIATION PROTECTION INSTRUMENTATION –
DOSIMETRY SYSTEMS WITH INTEGRATING PASSIVE DETECTORS
FOR INDIVIDUAL, WORKPLACE AND ENVIRONMENTAL MONITORING
OF PHOTON AND BETA RADIATION
1 Scope
This document applies to all kinds of passive dosimetry systems that are used for measuring:
– the personal dose equivalent H (10) (for individual whole body monitoring),
p
– the personal dose equivalent H (3) (for individual eye lens monitoring),
p
– the personal dose equivalent H (0,07) (for both individual whole body skin and local skin
p
for extremity monitoring),
– the ambient dose equivalent H*(10) (for workplace and environmental monitoring),
– the directional dose equivalent H'(3) (for workplace and environmental monitoring), or
– the directional dose equivalent H'(0,07) (for workplace and environmental monitoring).
This document applies to dosimetry systems that measure external photon and/or beta
radiation in the dose range between 0,01 mSv and 10 Sv and in the energy ranges given in
Table 1. All the energy values are mean energies with respect to the fluence. The dosimetry
systems usually use electronic devices for the data evaluation and thus are often computer
controlled.

The following beta radiation sources are suggested for the different mean energies: For 0,06 MeV: Pm;
90 90 106 106
for 0,8 MeV: Sr/ Y; for 1,2 MeV: Ru/ Rh.
b 60
1,25 MeV is the mean energy of photon radiation from Co.
c
For beta-particle radiation, an energy of 0,7 MeV is required to reach the radiation sensitive layers of the
eye lens in a depth of about 3 mm (approximately 3 mm of ICRU tissue).
d
For beta-particle radiation, an energy of 0,07 MeV is required to penetrate the dead layer of skin of 0,07 mm
(approximately 0,07 mm of ICRU tissue).
e
0,07 MeV, 0,8 MeV and 1,2 MeV beta mean energy are almost equivalent to an E of 0,225 MeV,
max
2,27 MeV and 3,54 MeV, respectively.
NOTE 1 In this document, “dose” means dose equivalent, unless otherwise stated.
NOTE 2 For H (10) and H*(10) no beta radiation is considered. Reasons:
p
a) H (10) and H*(10) are a conservative estimate for the effective dose which is not a suitable quantity for beta
p
radiation.
b) No conversion coefficients are available in ICRU 56, ICRU 57 or ISO 6980-3.
