Radiation protection instrumentation - Spectrometric radiation portal monitors (SRPMs) used for the detection and identification of illicit trafficking of radioactive material (IEC 62484:2020)

This document defines the performance requirements of installed monitors used for the detection and identification of gamma emitters and the detection of neutron radiation emitters. These monitors are commonly known as spectrometric radiation portal monitors or SRPMs. They are used to monitor vehicles, cargo containers, people, or packages and are typically used at national and international border crossings and ports of entry. SRPMs may be used at any location where there is a need for this type of monitoring.

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.

International Standard IEC 62484 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 62484 issued in 2010. This

edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) title modified;

b) making the standard consistent with the new standards for detection of illicit trafficking of

radioactive material (see the Introduction);

c) creating unformed functionality test for all environmental, electromagnetic and mechanical

tests and a requirement for the coefficient of variation of each nominal mean reading;

---------------------- Page: 11 ----------------------

e) adding information regarding climatic exposures.
The text of this International Standard is based on the following documents:
FDIS Report on voting
45B/969/FDIS 45B/971/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

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

Illicit and inadvertent movement of radioactive materials 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 of 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

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 62484 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 62484 issued in 2010. This

edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) title modified;

b) making the standard consistent with the new standards for detection of illicit trafficking of

radioactive material (see the Introduction);

c) creating unformed functionality test for all environmental, electromagnetic and mechanical

tests and a requirement for the coefficient of variation of each nominal mean reading;

---------------------- Page: 11 ----------------------

d) reference to IEC 62706 for the environmental, electromagnetic and mechanical test

conditions;
e) adding information regarding climatic exposures.
The text of this International Standard is based on the following documents:
FDIS Report on voting

INTRODUCTION

Illicit and inadvertent movement of radioactive materials 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 of 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 international standards. Several IEC standards

have been developed to address body-worn, hand-held and portal instruments, see Table 1.
