This European Standard was approved by CENELEC on 2008-02-01. 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.

Foreword
The text of the International Standard IEC 60861:2006, 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 60861 on 2008-02-01.
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) 2009-02-01

– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-02-01

Clauses, subclauses, notes, tables and figures which are additional to those in IEC 60861 are

Endorsement notice
The text of International Standard IEC 60861:2006 was approved by CENELEC as a
European Standard with agreed common modifications as given below.

COMMON MODIFICATIONS
1 Scope
In the first sentence of the fourth paragraph replace “continuous monitoring” with
“continuous monitoring (including discrete sequential measurement)”.
In the last sentence of the fourth paragraph replace “extraction and laboratory
analysis” with “extraction followed by laboratory analysis”.

2 Normative references
Add the following:
ISO 11929 (Series) Determination of the detection limit and decision threshold for
ionizing radiation measurements

3 Terms and definitions
3.1 water monitor
Replace the definition with “equipment intended for monitoring of radionuclides in
liquid effluents and surface waters”.

3.3 continuous measurement
Delete the whole definition.
3.5 discrete sequential measurement
Add the following note:
NOTE Z  Immediately after collection of the sample the activity of the sample will be measured, during
the time the next sample is collected. The time between taking each sample should be as short as
possible.
3.11 total equivalent window thickness (density thickness)
Replace “medium measured” with “surface of the medium of deposition to be
measured”.
Add at the end of the NOTE “… and the sample container (if any).”

3.16 decision threshold
Replace the first sentence of NOTE 1 with “The decision threshold is the critical
value of a statistical test designed in such a way that the probability of wrongly
rejecting the null hypothesis (H : the physical effect is not present) (error of the first
kind) is equal to a given value α.”.

3.25 sensitivity
Replace the first sentence with “for a given value of the measured quantity, the ratio
of the observed indication to the corresponding conventionally true value of the
measured quantity”.
Add the following note:
NOTE Z  This definition is specific to this standard.

5 Equipment design
5.1 Measurement and indication characteristics
5.1.1 Measurement characteristics
Add the following note below the current text:
NOTE Z  The decision threshold is calculated according to ISO 11929 series.

5.3 Sampling assembly
5.3.1 Sampling and exhaust pipes
Add “radioactive contamination” between “minimize” and “particle traps”.

6 Test procedures
6.5 Test sources
6.5.1 Reference sources
204 137
In the second paragraph delete “ Tl, or Cs,”.

7 Radiation performance tests
7.3 Linearity
7.3.2 Requirements
In the last sentence replace “reference curve” with “reference straight line”.

7.12 Influence of materials in suspension in liquid on activity measurement
7.12.2 Test method
In the second sentence of the first paragraph replace “conductivity of the used
solution shall” with “conductivity of the used solution should”.
