Reference radiation fields for radiation protection - Definitions and fundamental concepts (ISO 29661:2012, including Amd 1:2015)

ISO 29661:2012 defines terms and fundamental concepts for the calibration of dosemeters and equipment used for the radiation protection dosimetry of external radiation -- in particular, for beta, neutron and photon radiation. It defines the measurement quantities for radiation protection dosemeters and doserate meters and gives recommendations for establishing these quantities. For individual monitoring, it covers whole body and extremity dosemeters (including those for the skin and the eye lens), and for area monitoring, portable and installed dosemeters. Guidelines are given for the calibration of dosemeters and doserate meters used for individual and area monitoring in reference radiation fields. Recommendations are made for the position of the reference point and the phantom to be used for personal dosemeters.
ISO 29661:2012 also deals with the determination of the response as a function of radiation quality and angle of radiation incidence.
ISO 29661:2012 is intended to be used by calibration laboratories and manufacturers.

Referenzstrahlungsfelder für den Strahlenschutz - Definitionen und grundlegende Konzepte (ISO 29661:2012, einschließlich Amd 1:2015)

Diese Internationale Norm definiert Begriffe und grundlegende Konzepte für die Kalibrierung von Dosimetern und Geräten, die für die Strahlenschutzdosimetrie von externer Strahlung – insbesondere für Beta-, Neutro-nen- und Photonenstrahlung – Verwendung finden. Sie definiert die Messgrößen für Strahlen¬schutzdosimeter zur Messung der Dosis und Dosisleistung und gibt Empfehlungen für die Darstellung dieser Messgrößen. Für die Personendosimetrie behandelt sie Ganzkörper- und Teilkörperdosimeter (einschließlich derjenigen für die Haut und die Augenlinse) und für die Ortsdosimetrie tragbare und fest installierte Dosimeter. Für die Kalibrie¬rung von Dosimetern zur Messung der Orts- und Personendosis und Orts- und Personendosisleistung in Referenzstrahlungsfeldern werden Leitfäden gegeben. Für Personendosimeter werden Empfehlungen für die Position des Bezugspunktes und für das zu verwendende Phantom gegeben.
Diese Internationale Norm behandelt ebenfalls die Bestimmung des Ansprechvermögens als Funktion der Strahlungsqualität und des Strahleneinfallswinkels.
Sie ist gedacht für die Anwendung in Kalibrierlaboratorien und bei Herstellern.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 29661 was prepared by Technical Committee ISO/TC 85, Nuclear energy, nuclear technologies, and
radiological protection, Subcommittee SC 2, Radiological protection.

ISO 29661:2012(E)
Introduction
[1].[12]
International Standards ISO 4037, ISO 6980, ISO 8529 and ISO 12789 , with focus on photon, beta and
neutron reference radiation fields, are each divided into several parts: one part gives the methods of production
and characterization of reference radiation fields, and others describe the dosimetry of the reference radiation
qualities and the procedures for calibrating and determining the response of dosemeters and doserate meters
in terms of the operational quantities of the International Commission on Radiation Units and Measurements
[25] [26] [27] [28] [31]
(ICRU) .
The subject of these four International Standards is the same; they differ only in the kind of radiation each
addresses. Their terms and definitions, and most of the descriptions of methods and procedures given are
basically the same — whatever the radiation. Nevertheless, they do differ, more or less, from one to the other
in detail. This International Standard brings together terms and definitions and fundamental concepts common
to all of them. Thus, it serves to harmonize International Standards on radiation protection.
Besides definitions relating to calibration primary quantities, the operational quantities for area and individual
monitoring are specified. For area monitoring, the operational quantities are ambient dose equivalent, H*(10),
 
directional dose equivalents,H'(0,07,Ω) and H'(3,)Ω , and the appropriate dose rates. For individual monitoring
using personal dosemeters, the dose equivalent quantities, H (10), H (0,07) and H (3), and the respective dose
p p p
rates are available.
The method used to represent these operational quantities is the following. First, a basic (primary) quantity, such
as air kerma free-in-air, fluence or absorbed dose to soft tissue, is measured. Then the appropriate operational
quantity is derived by the application of the conversion coefficient that relates the basic (primary) quantity to
the selected operational quantity. The procedure for the calibration and the determination of the response of
radiation protection dosemeters is described in general terms. Depending on the type of dosemeter under test,
the position of the reference point is specified differently and the irradiation is either carried out on a phantom
(for personal dosemeters) or free in air (for area dosemeters or area survey meters).
With the publication of this International Standard, it is intended that ISO 4037, ISO 6980, ISO 8529 and
ISO 12789 be revised successively for further harmonization since, among other aspects, certain of their
definitions differ from those published here and the symbols chosen for this International Standard are more
consistent with ICRU reports and other International Standards used for radiation protection purposes.
