Water quality - Radium-226 - Part 1: Test method using liquid scintillation counting (ISO 13165-1:2022)
This document specifies the determination of radium-226 (226Ra) activity concentration in non-saline
water samples by extraction of its daughter radon-222 (222Rn) and its measurement using liquid
scintillation analysis.
The test method described in this document, using currently available scintillation counters, has a
detection limit of approximately 50 mBq·l−1. This method is not applicable to the measurement of other
radium isotopes.
Wasserbeschaffenheit - Radium-226 - Teil-1: Verfahren mit dem Flüssigszintillationszhler (ISO 13165-1:2022)
Dieses Dokument legt ein Verfahren für die Bestimmung der Aktivitätskonzentration von Radium 226 (226Ra) in nicht salzhaltigem Wasser durch Extraktion des Tochterisotops Radon 222 (222Rn) und dessen Messung mithilfe eines Flüssigszintillationszählers fest.
Das in diesem Dokument beschriebene Verfahren, bei der derzeit verfügbare Szintillationszähler verwendet werden, hat eine Nachweisgrenze von etwa 50 mBq· l−1 Dieses Verfahrens ist nicht für die Messung anderer Radiumisotope anwendbar.

Kakovost vode - Radij Ra-226 - 1. del: Preskusna metoda s štetjem s tekočinskim scintilatorjem (ISO 13165-1:2022)
Ta dokument določa metodo za določanje koncentracije aktivnosti radija 226 (226Ra) v vzorcih neslane vode s postopkom ekstrakcije njegovega potomca radona 222 (222Rn) in z merjenjem z analizo s tekočinskim scintilatorjem.
Preskusna metoda, opisana v tem dokumentu, s trenutno razpoložljivimi števci s tekočinskim scintilatorjem ima mejo zaznavnosti približno 50 mBq l−1. Ta metoda se ne uporablja za merjenje drugih izotopov radija.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction
