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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 85, Nuclear energy, nuclear technologies,
and radiological protection, Subcommittee SC 2, Radiation protection.
This second edition cancels and replaces the first edition (ISO 8529-3:1998), which has been technically
revised.
The main changes are as follows:
— The second and last edition of ISO 8529-1:2021 revised the neutron reference radiation fields
produced with radionuclide sources as well as those produced with monoenergetic neutrons,
thus requiring calculation of new conversion coefficients from neutron fluence to ambient dose
equivalent or personal dose equivalent.

Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
This corrected version of ISO 8529-3:2023 incorporates the following corrections:

Introduction
This document is closely related to ISO 8529-1 and ISO 8529-2 concerning the calibration of dosemeters
and doserate meters for neutron radiation. ISO 8529-1 specifies the reference neutron radiation fields,
in the energy range from thermal up to 20 MeV, and their production methods. ISO 8529-2 describes
the calibration fundamentals of radiation protection devices related to basic quantities characterising
the radiation field and specifies the procedures to be used for realising the calibration conditions
of radiation protection devices produced by calibration sources with emphasis on correction for
extraneous effects.
This document deals with dosemeters for area and individual monitoring. Unless differently specified,
the word "dosemeter" always refers to both. Area dosemeters are often called area monitors or area
survey meters, and dosemeters for individual monitoring are often called personal dosemeters or
personal dosimeters. This document describes procedures for calibrating and determining the response
in terms of the International Commission on Radiation Units and Measurements (ICRU) operational
[1] [2]
quantities. These are defined in ICRU Report 39 and ICRU Report51 . For radiation protection
purposes, these operational quantities are considered to be a sufficiently accurate approximation to
the protection quantities. For the purposes of this document, the emphasis will be on the evaluation
of the operational quantities at 10 mm depth defined in the body using conversion coefficients in
the appropriate phantom. Cold neutrons may present special problems in dosimetry and are outside
the scope of this document, as are the photon calibrations of instruments designed to measure both
photons and neutrons.
The determination of the response of dosemeters is essentially a three-step process. First, a primary
quantity such as the neutron fluence is determined at the point of test. Second, the reference point of
the device being calibrated is then placed at the point of test to determine the fluence response. Third,
the response of the device with respect to the appropriate operational quantity is then determined
by the application of conversion coefficients that relate the physical quantity (the fluence) to the
operational quantity (the dose equivalent). This document describes the methods and the conversion
coefficients to be used for the determination of the response of area and personal dosemeters in terms
of the respective ICRU operational quantities for neutrons.

Neutron reference radiation fields —
Part 3:
Calibration of area and personal dosemeters and
determination of their response as a function of neutron
energy and angle of incidence
1 Scope
This document provides guidance for those who calibrate protection-level dosemeters and doserate
meters for area and individual monitoring with reference neutron radiation fields. This includes the
determination of the response as a function of neutron energy and angle of incidence. The operational
[2]
quantities recommended in ICRU Report 51 are considered. In addition to the description of
procedures, this document includes appropriate definitions and conversion coefficients and provides
guidance on the statement of measurement uncertainties.

4.1 Neutron fields
This document deals with neutron reference radiation fields that shall be chosen from and produced
in accordance with ISO 8529-1 and characterized using the techniques of ISO 8529-2. In general, when
selecting an appropriate neutron field, it will be useful to take into account the specified energy and
dose or dose rate ranges of the dosemeter to be tested. The basic quantities characterizing the radiation
fields (energy and direction distribution of the neutron fluence) shall be determined and all necessary
corrections shall be considered in accord
