This European Standard was approved by CENELEC on 2011-06-20. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
Spain, Sweden, Switzerland and the United Kingdom.

Foreword
The text of the International Standard IEC 62363:2008, prepared by SC 45B, Radiation protection
instrumentation, of IEC TC 45, Nuclear instrumentation, together with the common modifications
prepared by the Technical Committee CENELEC TC 45B, Radiation protection instrumentation, was
submitted to the formal vote and was approved by CENELEC as EN 62363 on 2011-06-20.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2012-06-20

– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-06-20
Annex ZA has been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 62363:2008 was approved by CENELEC as a European
Standard with agreed common modifications as given below.

COMMON MODIFICATIONS
5 General characteristics
5.1 Classification
Last line, replace “Less than 10 keV” with “Less than 20 keV”

6 General test procedures
6.3  Reference radionuclides
Last line, replace “Less than 10 keV” with “Less than 20 keV”

8 Radiation characteristics
8.2 Detector profile
8.2.2 Method of test
In the first paragraph, replace “concentrically” with “centrally”
Insert as second paragraph:
“In the case of a rectangular detector three profiles shall be taken. One from the centre in the
direction normal to the shortest side of the sensitive area of the detector, another from the
centre in the direction normal to the longest side of the sensitive area of the detector and one
from the centre in the direction of a corner of the sensitive area of the detector. In the case of
square detectors the first above is unnecessary. In the case of a cylindrical detector there is
only a single profile.”
8.3 Surface emission rate response
8.3.1 General
First paragraph, last sentence: replace “with sensitive volumes in excess of 20 ml” with “with
large sensitive volumes and/or areas”

Annex A
Replace title with “Limit distances for typical cylindrical detectors”
Replace in the title of the right column of Table A.1 “50 ml” with “2 ml”
Replace the second note in Table A.1 with “Be refers to a detector with a beryllium window of
area 8 cm .”
Add the following new annex.
Annex ZA
