RADIATION PROTECTION INSTRUMENTATION – EQUIPMENT FOR
MEASURING THE ACTIVITY CONCENTRATION OF GAMMA-EMITTING
RADIONUCLIDES IN FOODSTUFFS
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 61563 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 published in 2001. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The previous edition applied to handheld-type and portable-type instruments. This edition
applies to transportable-type and installed-type instruments, as well as the scope of the
previous edition. The handheld-type and portable-type instruments are mainly used in
case of a post accidental situation, however, the transportable-type and installed-type
instruments can be used through recovery phase.
b) Uncertainty of measurement according to GUM is introduced.
c) Detection limit defined in ISO 11929 is introduced to specify a minimum detectable activity.
---------------------- Page: 11 ----------------------
SIST EN IEC 61563:2021
– 6 – IEC 61563:2019 © IEC 2019
d) Environmental requirements, mechanical requirements and electromagnetic requirements
are updated according to IEC 62706.
e) Sample format of measuring report is introduced as Annex C (informative).
The text of this International Standard is based on the following documents:
FDIS Report on voting
45B/931/FDIS 45B/936/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

1 Scope
This document applies to instruments used to measure the activity and/or activity
concentration of gamma-emitting radionuclides in food and/or foodstuffs. This document
applies to instruments used both as gross count type instruments and pulse height analysing
type instruments used in field conditions and in measurement facilities. This document does
not apply to high-resolution spectrometers that use germanium detectors.
The instruments to which this document applies can be used to measure the activity and
activity concentration of gamma-emitting radionuclides for a wide variety of samples, such as
soil, sewage, plant, and animal life.
The object of this document is to establish performance requirements, to provide test methods
and to specify general characteristics, general test conditions, and radiological, environmental,
mechanical and electromagnetic characteristics to be used to determine whether an
instrument meets the requirements of this document. The test results provide information to
end-users and manufacturers regarding the capability of instrument for reliable measurement
of the activity and/or activity concentration of gamma-emitting radionuclides.

____________
RADIATION PROTECTION INSTRUMENTATION – EQUIPMENT FOR
MEASURING THE ACTIVITY CONCENTRATION OF GAMMA-EMITTING
RADIONUCLIDES IN FOODSTUFFS
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 61563 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 published in 2001. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The previous edition applied to handheld-type and portable-type instruments. This edition
applies to transportable-type and installed-type instruments, as well as the scope of the
previous edition. The handheld-type and portable-type instruments are mainly used in
case of a post accidental situation, however, the transportable-type and installed-type
instruments can be used through recovery phase.
b) Uncertainty of measurement according to GUM is introduced.
c) Detection limit defined in ISO 11929 is introduced to specify a minimum detectable activity.

d) Environmental requirements, mechanical requirements and electromagnetic requirements
are updated according to IEC 62706.
e) Sample format of measuring report is introduced as Annex C (informative).
The text of this International Standard is based on the following documents:
FDIS Report on voting
45B/931/FDIS 45B/936/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.

RADIATION PROTECTION INSTRUMENTATION – EQUIPMENT FOR
MEASURING THE ACTIVITY CONCENTRATION OF GAMMA-EMITTING
RADIONUCLIDES IN FOODSTUFFS
1 Scope
This document applies to instruments used to measure the activity and/or activity
concentration of gamma-emitting radionuclides in food and/or foodstuffs. This document
applies to instruments used both as gross count type instruments and pulse height analysing
type instruments used in field conditions and in measurement facilities. This document does
not apply to high-resolution spectrometers that use germanium detectors.
The instruments to which this document applies can be used to measure the activity and
activity concentration of gamma-emitting radionuclides for a wide variety of samples, such as
soil, sewage, plant, and animal life.
The object of this document is to establish performance requirements, to provide test methods
and to specify general characteristics, general test conditions, and radiological, environmental,
mechanical and electromagnetic characteristics to be used to determine whether an
instrument meets the requirements of this document. The test results provide information to
end-users and manufacturers regarding the capability of instrument for reliable measurement
of the activity and/or activity concentration of gamma-emitting radionuclides.
This document does not apply to sample preparation.
