(IDENTIFICATION) OF SCINTILLATORS AND SCINTILLATION
DETECTORS AND STANDARD DIMENSIONS OF SCINTILLATORS

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 60412 has been prepared by IEC technical committee 45: Nuclear
instrumentation.
This third edition cancels and replaces the second edition published in 2007. It constitutes a
technical revision.
The main technical changes with regard to the previous edition are as follows:
• Nomenclature of scintillation detectors was expanded by phoswich detector and single-line
multi-channel detector.
• Some missing positions in the nomenclature of the previous edition were filled out.

The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
INTRODUCTION
Recently each manufacturer of scintillation detectors has been offering its own nomenclature
presenting in it, in the first place, their trademarks and introducing their own abbreviations
(identification). The nomenclature of scintillators and scintillation detectors is quite
complicated and usually includes type of detector, scintillator’s material, geometry and
dimensions of scintillator, materials of housing and window, type and dimensions of
photomultiplier tube or photodiode, presence of additional electronic devices and some other
characteristics. Different manufacturers offer different content and different order of
characteristic designations in the identifiers of their products. This makes perception by a
customer of the meaning of symbols in these identifiers difficult. The situation can be
improved through introducing a uniform system of nomenclature (identification) of scintillators
and scintillation detectors. For this purpose it is advisable to use designations of separate
parameters in a strict order, guided by a principle: from the main parameters to secondary
ones. This approach will introduce uniformity into the system of nomenclature (identification)
of scintillators and scintillation detectors, as well as facilitate the perception of this system
and correct selection of products by the customer.

NUCLEAR INSTRUMENTATION – NOMENCLATURE
(IDENTIFICATION) OF SCINTILLATORS AND SCINTILLATION
DETECTORS AND STANDARD DIMENSIONS OF SCINTILLATORS

1 Scope
This International Standard gives guidelines for scintillation detectors and scintillators
nomenclature (identification) and standard dimensions of scintillators.
This International Standard is applicable to all types of solid organic and inorganic scintillators
used in detectors for scintillation counting and spectrometry.
The object of this standard is to define a standardized nomenclature for scintillation detectors
in which most of the properties can be found.
The object of this standard is to standardize the dimensions of bare scintillators in order to
facilitate interchangeability of non-encapsulated scintillators and to facilitate intercomparisons
of measurements with encapsulated scintillators.
Liquid scintillators are not addressed by this standard.
NOTE The identification labels laid down in Clause 2 of the present standard include certain dimensions which
may be expressed in millimetres or inches. The SI system recommends the use of millimetres rather than inches.
2 Nomenclature of scintillation detectors and scintillators
2.1 General
The identification of a scintillation detector is specified by a predefined sequence of
specification items described below. Each specification item refers to a specific property of
the detector material and/or construction.
The general structure of an identification label includes symbols, described in 2.2 to 2.13, and
given in the same order in which these subclauses are provided.
