Water quality - Radium-226 - Part 3: Test method using coprecipitation and gamma-ray spectrometry (ISO 13165-3:2024)
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 Gamma-Ray-Spektrometrie (ISO 13165-3:2024)
Dieses Dokument legt ein Verfahren zur Bestimmung der Aktivitätskonzentration von Radium 226 (226Ra) in allen Arten von Wasser durch Mitfällung und anschließende Gammaspektrometrie fest (siehe ISO 20042 [7]).
Das Verfahren beschreibt die Bestimmung der Aktivitätskonzentrationen von löslichem 226Ra von mehr als 0,002 Bq ⋅ l-1 unter dem Einsatz eines Probenvolumens von bis zu 100 l eines beliebigen Wassertyps.
Für Wasserproben mit einem Volumen von weniger als 1 l kann eine direkte Gammaspektrometrie nach ISO 10703 jedoch mit einer höheren Nachweisgrenze durchgeführt werden. Die typischen Nachweisgrenzen für Proben von 1 l bis 5 l liegt im Bereich von 0,002 bis 0,000 40 Bq·l−1[8].
ANMERKUNG Dieses Prüfverfahren kann angepasst werden, um andere natürlich vorkommenden Radiumisotope, wie 223Ra, 224Ra und 228Ra, zu bestimmen, sofern deren Aufwachszeiten berücksichtigt werden.
WARNUNG — Anwender dieses Dokuments sollten mit der üblichen Laborpraxis vertraut sein. Dieses Dokument gibt nicht vor, alle unter Umständen mit der Anwendung des Verfahrens verbundenen Sicherheitsaspekte anzusprechen. Es liegt in der Verantwortung des AnwendersN1, angemessene Sicherheits und Schutzmaßnahmen zu treffen und sicherzustellen, dass diese mit nationalen Festlegungen übereinstimmen.
WICHTIG — Es ist unbedingt erforderlich, dass die Untersuchungen nach diesem Dokument von entsprechend qualifiziertem Personal durchgeführt werden.
Qualité de l'eau - Radium-226 - Partie 3: Méthode d’essai par coprécipitation et spectrométrie gamma (ISO 13165-3:2024)
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).
