Endorsement notice
The text of the International Standard IEC 62022:2004 was approved by CENELEC as a European
Standard with agreed common modifications as given below.
COMMON MODIFICATIONS
Replace “operational setting” with “operating setting” all over the document.
2 Normative references
Replace the references to IEC 61000-4 series with their latest editions.
4 Design requirements
4.1 General characteristics
Add at the end of the first paragraph: “. threshold. The alarm threshold is not a fixed value,
but an expected value depending on the measuring conditions, e.g. the material and energy
ranges expected.”
Replace the last paragraph with:
In the case of the dynamic mode (the vehicle passing the equipment) alarm occurs when
there is a statistically significant increase in the detected fluence rate of gamma photons
when the vehicle is passing the detection system. This fluence may however be less than
that due to normal background.
Add a new paragraph below the current text, reading:
In the case of the static mode (vehicle stationary within the equipment) an alarm occurs
when the fluence rate of gamma photons detected is greater than a pre-established level.
4.2 Configuration
Replace the first paragraph with:
The equipment is composed of one or several radiation detection assemblies adjacent to
the vehicle in the static mode and close to the vehicle whilst it passes in the dynamic mode,
and an information treatment assembly, linked to an alarm assembly.
Replace the fifteenth paragraph with:
Sensors should indicate the approach of the vehicle to inhibit any further storage of
background information. Further sensors should indicate the vehicle is in the monitoring
position or passing through the monitoring area.
Replace the last paragraph with:
Equipment shall be provided with appropriate facilities for indicating faults, for example loss
of detector voltage of failure of electronics. The number and type of faults to be indicated
shall be by agreement between the manufacturer and purchaser.
4.3 Indication facilities
Begin the penultimate paragraph with “It should be possible to transfer these data to an
additional …”

INSTALLED MONITORS FOR THE CONTROL AND DETECTION
OF GAMMA RADIATIONS CONTAINED IN RECYCLABLE OR
NON-RECYCLABLE MATERIALS TRANSPORTED BY VEHICLES
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62022 has been prepared by subcommittee 45B: Radiation
protection instrumentation, of IEC technical committee 45: Nuclear instrumentation.
The text of this standard is based on the following documents:

INSTALLED MONITORS FOR THE CONTROL AND DETECTION
OF GAMMA RADIATIONS CONTAINED IN RECYCLABLE OR
NON-RECYCLABLE MATERIALS TRANSPORTED BY VEHICLES
1 Scope
This International Standard is applicable to installed monitors for the control and detection of
radioactivity of gamma emitters contained in recyclable or non-recyclable material waste to be
transported by vehicles.
This standard is designed to provide the purchaser with an indication of the performance of
the equipment in detecting radioactive sources left in the material being monitored, and not to
measure quantity.
This standard does not apply to hand-held equipment. It is not applicable to the monitoring of
materials on conveyors, in grabs or being moved by electromagnets.
This standard is not intended for the monitoring of radioactive waste or detection of fissile
materials.
The object of this standard is to define an installed monitor for the control and detection of
radioactivity of gamma emitters contained in recyclable or non-recyclable materials
transported by vehicle, the conceptual requirements, general characteristics, mechanical
characteristics, environmental conditions, minimal requirements, test procedures and
documentation.
The selection of the location of the instrumentation on the site needs to be optimised to
achieve the best performance of measurement, but this is beyond the scope of this standard.
The gamma radiation detected by these monitors may be emitted by one or several discrete
radioactive sources included in the loading, or by the presence of radioactive material in the
vehicle being monitored.
These monitors are to be used outdoors. The radiations detected are gamma emissions of
energy at least from 50 keV to 1 500 keV.
It is advantageous if the equipment can give the approximate location of a radioactive source
but this is not a mandatory requirement of this standard.
Conformance with the requirements of this standard is no guarantee that a radioactive source
will always be discovered. The shielding of the high-density materials will mean radioactive
substances buried deep in the material could be missed.
