Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13160 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 3,
Radiological methods.

INTERNATIONAL STANDARD ISO 13160:2012(E)
Water quality — Strontium 90 and strontium 89 — Test methods
using liquid scintillation counting or proportional counting
WARNING — Persons using this International Standard should be familiar with normal laboratory
practice. This document does not purport to address all of the safety problems, if any, associated with
its use. It is the responsibility of the user to establish appropriate safety and health practices and to
ensure compliance with any national regulatory conditions.
IMPORTANT — It is absolutely essential that tests conducted in accordance with this International
Standard be carried out by suitably qualified staff.
1 Scope
This International Standard specifies the test methods and their associated principles for the measurement
90 90 89
of the activity of Sr in equilibrium with Y, and Sr, pure beta-emitting radionuclides, in water samples.
Different chemical separation methods are presented to produce strontium and yttrium sources, the activity of
which is determined using a proportional counter (PC) or liquid scintillation counter (LSC). The selection of the
test method depends on the origin of the contamination, the characteristics of the water to be analysed, the
required accuracy of test results and the available resources of the laboratories.
These test methods are used for water monitoring following, past or present, accidental or routine, liquid or
gaseous discharges. It also covers the monitoring of contamination caused by global fallout.
When fallout occurs immediately following a nuclear accident, the contribution of Sr to the total amount of
strontium activity is not negligible. This International Standard provides the test methods to determine the
90 89
activity concentration of Sr in presence of Sr.
