Water quality - Radium-226 - Part 3: Test method using coprecipitation and gamma-spectrometry (ISO 13165-3:2016)
ISO 13165-3:2016 specifies the determination of radium-226 (226Ra) activity concentration in all types of water by coprecipitation followed by gamma-spectrometry (see ISO 18589‑3).
The method described is suitable for determination of soluble 226Ra activity concentrations greater than 0,02 Bq l−1 using a sample volume of 1 l to 100 l of any water type.
For water samples smaller than a volume of 1 l, direct gamma-spectrometry can be performed following ISO 10703 with a higher detection limit.
NOTE This test method also allows other isotopes of radium, 223Ra, 224Ra, and 228Ra, to be determined.
Wasserbeschaffenheit - Radium 226 - Teil 3: Verfahren mittels Kopräzipitation und Gammaspektrometrie (ISO 13165-3:2016)
Dieser Teil von ISO 13165 legt die Bestimmung der Aktivitätskonzentration von Radium 226 (226Ra) in allen Arten von Wasser durch Mitfällung und anschließende Gammaspektrometrie fest (siehe ISO 18589 3).
Das beschriebene Verfahren eignet sich zur Bestimmung der Aktivitätskonzentrationen von löslichem 226Ra von mehr als 0,02 Bq l−1 bei einem Probenvolumen von 1 l bis 100 l eines beliebigen Wassertyps.
Für Wasserproben mit einem Volumen von weniger als 1 l kann eine direkte Gammaspektrometrie nach ISO 10703 mit einer höheren Nachweisgrenze durchgeführt werden.
ANMERKUNG Mit diesem Prüfverfahren können auch andere Radiumisotope, 223Ra, 224Ra und 228Ra, bestimmt werden.
Qualité de l'eau - Radium 226 - Partie 3: Méthode d'essai par coprécipitation et spectrométrie gamma (ISO 13165-3:2016)
L'ISO 13165-3:2016 spécifie la détermination de l'activité volumique du radium 226 (226Ra), dans tous les types d'eaux par coprécipitation suivie d'une spectrométrie gamma (voir l'ISO 18589‑3).
La méthode décrite est applicable pour la détermination de l'activité volumique du 226Ra soluble ayant une activité volumique en 226Ra supérieure à 0,02 Bq l−1 en utilisant un volume d'échantillon compris entre 1 l et 100 l de tout type d'eau.
Pour des échantillons d'eau inférieurs à un volume de 1 l, la spectrométrie gamma directe peut être effectuée en se conformant à l'ISO 10703 avec une limite de détection supérieure.
NOTE Cette méthode d'essai permet également le mesurage d'autres isotopes du radium (223Ra, 224Ra et 228Ra).

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).
