SPECTROSCOPY-BASED ALARMING PERSONAL RADIATION
DETECTORS (SPRD) FOR THE DETECTION OF ILLICIT TRAFFICKING
OF RADIOACTIVE MATERIAL
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.

RADIATION PROTECTION INSTRUMENTATION –
SPECTROSCOPY-BASED ALARMING PERSONAL RADIATION
DETECTORS (SPRD) FOR THE DETECTION OF ILLICIT TRAFFICKING
OF RADIOACTIVE MATERIAL
1 Scope and object
This International Standard applies to Spectroscopy-based alarming Personal Radiation
Detectors (SPRD) which represent a new instrument category between alarming Personal
Radiation Devices (PRD) and Radionuclide Identification Devices (RID). SPRDs are advanced
PRDs that can be worn on a belt or in a pocket to alert the wearer of the presence of a
radiation source. They are not intended for accurate measurement of personal or ambient
dose equivalent (rate). In addition to the features of conventional PRDs, SPRDs provide rapid
simultaneous search and identification capability to locate and identify radiation sources.
They can discriminate innocent alarms such as Naturally Occurring Radioactive Materials
(NORM) or medical radionuclides against industrial sources or Special Nuclear Material
(SNM). Because of their limited sensitivity, SPRDs cannot replace RIDs. For first responders,
SPRDs can be particularly useful for immediate response measures.
This standard does not apply to the performance of radiation protection instrumentation which
is covered in IEC 61526 and IEC 62401.
The object of this standard is to establish performance requirements, provide examples of
acceptable test methods and to specify general characteristics, general test conditions,
radiological, environmental, mechanical and electromagnetic characteristics that are used to
determine if an instrument meets the requirements of this standard. The results of tests
performed provide information to end-users and manufacturers on instrument capability for
reliable detection, localization and identification of radiation sources.
Obtaining operating performance that meets or exceeds the specifications as stated in this
standard depends upon properly establishing appropriate operating parameters, maintaining
calibration, implementing a suitable maintenance program, auditing compliance with quality
control requirements and providing proper training for operating personnel.

3.1 Terms and definitions
For the purposes of this document, the following terms and definitions, as well as those given
in IEC 60050-393 and IEC 60050-394 apply.
3.1.1
acceptable or correct identification
when an instrument correctly identifies only the radio nuclides present
3.1.2
accuracy of measurement
closeness of the agreement between the result of a measurement and the conventionally true
value of the measurand
Note 1 to entry: “Accuracy” is a quantitative concept.
Note 2 to entry: The term precision should not be used for “accuracy”.
[SOURCE: IEC 60050-394:2007, 394-40-35]
3.1.3
alarm
an audible, visual, or other signal activated when the instrument reading exceeds a preset
value or falls outside of a preset range
3.1.4
alarm criteria
condition that causes an instrument to alarm
3.1.5
ambient dose equivalent H*(10)
dose equivalent at a point in a radiation field, produced by the corresponding aligned and
expanded field, in the ICRU sphere at a depth of 10 mm, on the radius opposing the direction
of the aligned field (see ICRU Report 39 and 47)
Note 1 to entry: In defining these quantities, it is useful to stipulate certain radiation fields that are derived from
the actual radiation field. The terms "expanded" and "aligned" are used to characterise these derived radiation
fields. In the expanded field, the fluence and its angular and energy distribution have the same values throughout
the volume of interest as in the actual field at the point of reference. In the aligned and expanded field, the fluence
and its energy distribution are the same as in the expanded field but the fluence is unidirectional.

62618 © IEC:2013 – 9 –
Note 2 to entry: The ICRU sphere (see ICRU Report 33) is a 30 cm diameter, tissue-equivalent sphere with a
–3
density of 1 g⋅cm and a mass composition of tissue equivalent material (see IEC 60050-393, 393-14-78).
Note 3 to entry: The recommended depth d, for environmental monitoring in terms of H*(d) is 10 mm, and H*(d)
may then be written as H*(10).
Note 4 to entry: An instrument that has an isotropic response and is calibrated in terms of H*(d) will measure
H*(d) in radiation fields that are uniform over the dimensions of the instrument.
Note 5 to entry: The definition of H*(d) requires the design of the instrument to take account of backscatter.

3.4 Simplification of terms
Within this standard the following simplification of terms is used to accelerate reading and to
facilitate understanding of the text:
•
“dose rate” replaces “ambient dose equivalent rate H *(10)”
SPRDs are not intended for accurate measurement of the personal dose equivalent (rate)
H (10), therefore no reference to such quantities is needed and the term “dose (rate)” can
p
unambiguously replace the term “ambient dose equivalent (rate)” throughout the standard.
4 General test procedure
4.1 Nature of tests
The required standard test conditions for influence quantities, such as temperature and
pressure, as well as those for other quantities that may influence the performance of
instruments, are given in Table A.1. Acceptable testing ranges for these quantities shall be
met, except where the effect of the condition or quantity itself is being tested.
The tests in this standard are to be considered as type tests (see Table B.1) unless otherwise
stated. The user may employ certain parts of the standard as acceptance tests. The required
specifications are evaluated by the tests given in the appropriate Clauses. All tests in this
standard shall be performed using the same instrument setup with any accessories included
with the instruments. Where no test is specified, it is understood to mean that the
characteristic can be verified by observation or consultation of the manufacturer’s
specifications.
4.2 Reference conditions and standard test conditions
4.2.1 General
Ideally, measurements or calibrations should be carried out under reference conditions. Since
it is not always possible to maintain these conditions, a small interval around the reference
values may be used (these are the standard test conditions).
Reference and standard test conditions are given in Table A.1. Reference conditions are
those conditions to which the performances of the instrument are valid and standard test
conditions indicate the necessary tolerances in practical testing.
Except where otherwise specified, the tests in this standard shall be performed under the
standard test conditions given in the third column of Table A.1.
4.2.2 Tests performed under standard test conditions
Tests which are performed under standard test conditions are listed in Table B.1 which
indicates, for each characteristic under test, the requirements according to the Clause where
the corresponding test method is described. For these tests, the value of temperature,
pressure and relative humidity at the time of the test shall be stated.
4.2.3 Tests performed with variation of influence quantities
For tests intended to determine the effects of variations in the influence quantities given in
Table 1, all other influence quantities shall be maintained within the limits for the standard
test conditions given in Table A.1 unless otherwise specified in the test procedure concerned.
4.3 Statistical fluctuations
For any test involving the use of radiation, if the magnitude of the statistical fluctuations of the
indication arising from the random nature of radiation alone is a significant fraction of the

variation of the indication permitted in the test, then sufficient readings shall be taken to
ensure that the m
