Water quality - Radium-226 - Part 2: Test method using emanometry (ISO 13165-2:2014)
ISO 13165-2:2014 specifies the determination of radium-226 (226Ra) activity concentration in all types of water by emanometry. The method specified is suitable for the determination of the soluble, suspended, and total 226Ra activity concentration in all types of water with soluble 226Ra activity concentrations greater than 0,02 Bq l−1. In water containing high activity concentrations of 228Th, interference from 220Rn decay products can lead to overestimation of measured levels.
Wasserbeschaffenheit - Radium 226 - Teil 2: Verfahren mittels Emanometrie (ISO 13165-2:2014)
Dieser Teil von ISO 13165 legt die Bestimmung der Aktivitätskonzentration von Radium 226 (226Ra) in allen Arten von Wasser mittels Emanometrie fest.
Das beschriebene Verfahren eignet sich zur Bestimmung der Gesamtaktivitätskonzentration von löslichem, suspendiertem 226Ra in allen Arten von Wasser mit löslichen 226Ra Aktivitätskonzentrationen von mehr als 0,02 Bq l−1.
In Wasser mit hohen Aktivitätskonzentrationen von 228Th können Störungen durch220Rn Zerfallsprodukte zur Überbewertung der gemessenen Stände führen (siehe Bild A.2).
Qualité de l'eau - Radium 226 - Partie 2: Méthode d'essai par émanométrie (ISO 13165-2:2014)
L'ISO 13165-2:2014 spécifie la détermination de l'activité volumique du radium 226 (226Ra), dans tous types d'eaux par émanométrie.
La méthode spécifiée est applicable pour la détermination de l'activité volumique du 226Ra soluble, total et particulaire dans tous types d'eaux d'activité volumique en 226Ra supérieure à 0,02 Bq l−1.
Dans les eaux fortement chargées en 228Th, l'interférence due aux descendants du 220Rn peut conduire à une surestimation des niveaux mesurés.

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 and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
