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).

Introduction
The direct (in vivo) measurement of radionuclides emitting penetrating radiations (X- and gamma rays)
in the body is an important technique in radiological protection. Along with the appropriate biokinetic
[5]
and dosimetric models, the results can be used to assess doses due to intakes of radionuclides . These
measurements and assessments are typically done
— routinely among radiation workers in occupational radiation protection, and
— among members of the public, emergency workers or helpers in a nuclear or radiological emergency.
In vivo monitoring may also be used to identify the level of exposure of an individual in a criticality
[5]
incident through the measurement of activated body sodium .
In vivo measurements may be made by dosimetry laboratories with dedicated facilities, in nuclear
facilities using whole-body or partial body scanners, or in hospitals or universities with appropriate
equipment. The most common direct (in vivo) methods are whole-body, lung, and thyroid counting.
Participating in performance testing programmes with suitable phantoms is commonly required
by national regulatory bodies as part of the accreditation of in vivo dosimetry service laboratories
for the validation of bioassay methods. For other facilities making in vivo measurements, such as
nuclear facilities, hospitals, and universities, participating in intercomparisons can help monitor the
performance, identify problems, and provide education and training opportunities. ISO 28218 provides
performance criteria for radiobioassay including in vivo monitoring. The general design requirements
and performance characteristics of in vivo measurement instrumentation, including test procedures
[4]
for performance control, are described in IEC 61582 .
General requirements on proficiency testing and statistical methods for evaluation are given
[3] [2]
in ISO/IEC 17043 and ISO 13528 , respectively.
The purpose of this document is to give a fuller set of requirements and recommendations for
proficiency test organizers than given in the standards mentioned above, including
— planning and announcement of testing actions,
— selection of radionuclides,
— selection of activities to be used for testing,
— preparation of test sources,
— selection of phantoms,
— measurement of phantoms,
— analysis of results provided by the participants, and
— reporting.

INTERNATIONAL STANDARD ISO 23588:2023(E)
Radiological protection — General requirements for
proficiency tests for in vivo radiobioassay
1 Scope
This document specifies general requirements for proficiency tests that are offered to in vivo bioassay
measurement facilities operating a whole-body counter (WBC) or partial body counter (PBC) for
monitoring of persons.
It specifies minimum requirements for proficiency testing applicable to dosimetry laboratories that
have dedicated facilities for in vivo monitoring and where accreditation is required as part of providing
the service. It also provides general requirements for proficiency testing that may include a larger
group of non-accredited laboratories that may perform measurements as part of worker surveillance
or in response to an emergency.
This document covers proficiency tests that involve only the quantification of radionuclides and tests
that require the identification of radionuclides and their activity.
This document does not define specific requirements on administrative aspects of proficiency testing,
such as shipping and finance, that may be the subject of national or international regulation.
