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 62327 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 of IEC 62327, issued in 2006. It
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) addition of detailed methods of test;
b) revised identification test acceptance criteria for environmental tests;
c) changed format to match SC 45B template.

INTRODUCTION
Illicit and inadvertent movement of radioactive materials in the form of radiation sources and
contaminated metallurgical scrap has become a problem of increasing importance.
Radioactive sources out of regulatory control, so-called “orphan sources”, have frequently
caused serious radiation exposures and widespread contamination. Although illicit trafficking
in nuclear and other radioactive materials is not a new phenomenon, concern about a nuclear
“black market” has increased in the last few years particularly in view of its terrorist potential.
In response to the technical policy of the International Atomic Energy Agency (IAEA), the
World Customs Organization (WCO) and the International Criminal Police Organization
(Interpol) related to the detection and identification of special nuclear materials and security
trends, nuclear instrumentation companies are developing and manufacturing radiation
instrumentation to assist in the detection of illicit movement of radioactive and special nuclear
materials. This type of instrumentation is widely used for security purposes at nuclear
facilities, border control checkpoints, and international seaports and airports. However, to
ensure that measurement results made at different locations are consistent, it is imperative
that radiation instrumentation be designed to rigorous specifications based upon agreed
performance requirements stated in this document. IEC standards have also been developed
to address personal radiation detectors, radiation portal monitors, highly sensitive gamma and
neutron detection systems, spectrometric personal radiation detectors, and backpack-based
radiation detection and identification systems. Table 1 below contains a list of those
standards.

dose equivalent (rate) at a point in a radiation field, produced by the corresponding aligned
and expanded field, in the ICRU sphere at a depth d, on the radius opposing the direction of
the aligned field
Note 1 to entry: This definition does not include the notes that are part of definition IEC 60050-395:2014,
395-05-43.
3.1.4
background
radiation field in which there are no external sources present other than those in the natural
radiation field at the location of the measurements
3.1.5
coefficient of variation
ratio of the standard deviation s to the arithmetic mean of a set of n measurements x given
i
by the following formula:
3.1.6
confidence indicator
typically a numeric value assigned to a radionuclide identification result as to whether the
identified radionuclide is present
3.1.7
conventionally true value
best estimate of the true value of a radiation field or source used for testing or calibration of
equipment
3.1.8
error of indication
difference between the indicated value ν of a quantity and the conventionally true value, CTV,
of that quantity at the point of measurement
3.1.9
integration time
length of time used for collection of data to obtain a result
3.1.10
reference point
location marked on the instrument or described in the manual, used to establish radiation
source-to-instrument distances and orientation for calibration or test purposes
3.1.11
relative intrinsic error
ε
REL
difference between the instrument’s reading, M, and the conventionally true value, CTV, of the
quantity being measured divided by the conventionally true value when subjected to a
specified reference quantity under specified reference conditions as given by the formula:

3.1.12
restricted mode
operating mode used to access spectral data and to control the parameters that can affect the
result of a measurement (for example: radionuclide library, routine function control, calibration
parameters, alarm thresholds, etc.)
Note 1 to entry: May also be called expert mode.
Note 2 to entry: Access to this mode should be limited through password protection or other similar methods.
3.1.13
routine mode
operating mode that includes detection and identification of radionuclides, and estimation of
the ambient dose equivalent rate
Note 1 to entry: May also be called easy mode.
3.1.14
stabilization time
duration, measured from the initial application of power, required for an instrument to indicate
that it is operational
3.1.15
type test
conformity test on one or more specimens of a product representative of the production
3.1.16
uncertainty
parameter, associated with the result of a measurement, that characterizes the dispersion of
the values that could reasonably be attributed to the measurand
Note 1 to entry: Uncertainty of measurement comprises, in general, many components. Some of these
components may be evaluated from statistical distribution of the results of series of measurements and can be
characterized by experimental standard deviations. The other components, which can also be characterized by
experimental standard deviations, are evaluated from assumed probability distributions based on experience or
other information.
Note 2 to entry: It is understood that the result of the measurement is the best estimate of the value of the
measurand and that all components of uncertainty, including those arising from systematic effects, such as
components associated with corrections and reference standards, contribute to the dispersion.

3.3 Quantities and units
In this document, units of the International System (SI) are used . The definitions of radiation
quantities are given in IEC 60050-395.
The following units may also be used:
–19
– for energy: electron-volt (symbol: eV), 1 eV = 1,602 x 10 J;
– for time: years (symbol: y), days (symbol: d), hours (symbol: h), minutes (symbol: min);
– for temperature: degrees Celsius (symbol: ºC), 0 ºC = 273,15 K.
Multiples and submultiples of SI units will be used, when practicable, according to the SI
system.
4 General characteristics and requirements
4.1 General
RIDs are used for the detection, localization, and identification of radioactive material and for
estimation of the ambient dose equivalent rate. They are hand-held, battery-powered
instruments most commonly used for the detection and identification of illicit trafficking of
radioactive material. They typically measure the photon energy spectrum and identify the
radionuclide by comparison with an internal radionuclide library. RIDs may also detect
neutrons.
The following are important design features:
– a display that is readable in low light (< 150 lx) and bright light (> 10 000 lx) conditions,
– user friendly controls, a menu structure that is simple and easy to follow, restricted access
to critical operating parameters, and switches and other controls that minimize or prevent
inadvertent operation.
NOTE During the development of this document, a desire for a RID to provide a simple user display for
identification results was noted. The display discussed would provide identification results in the form of, for
example, a green or red display to indicate that the radionuclide(s) identified was either not of interest or of
possible interest, respectively. At the time of this revision, no specific functional requirements had been
established. Requirements for the capability may be part of future revisions of this document.
4.2 Radiation detectors
RIDs may use multiple detectors to detect gamma radiation, identify radionuclides, and detect
neutrons.
4.3 Personal protection alarm
4.3.1 Requirements
An alarm shall be provided to alert the user that the ambient gamma dose equivalent rate is
above a threshold level. The alarm threshold shall be adjustable through the restricted mode.
The alarm shall be both audible and visual with an "acknowledge" or other similar control to
silence the audible function. It shall not be possible to deactivate both audible and visual
indicators at the same time.
4.3.2 Method of test
a) Following the instructions provided by the manufacturer, set the personal protection alarm
–1
to activate at for example, 10 µSv h .
