Water quality - Radon-222 - Part 2: Test method using gamma-ray spectrometry (ISO 13164-2:2013)
ISO 13164-2:2013 specifies a test method for the determination of radon-222 activity concentration in a sample of water following the measurement of its short-lived decay products by direct gamma-spectrometry of the water sample.
The radon-222 activity concentrations, which can be measured by this test method utilizing currently available gamma-ray instruments, range from a few becquerels per litre to several hundred thousand becquerels per litre for a 1 l test sample.
This test method can be used successfully with drinking water samples. The laboratory is responsible for ensuring the validity of this test method for water samples of untested matrices.
An annex gives indications on the necessary counting conditions to meet the required sensitivity for drinking water monitoring.
Wasserbeschaffenheit - Radon-222 - Teil 2: Verfahren mittels Gammaspektrometrie (ISO 13164-2:2013)
Dieser Teil von ISO 13164 legt ein Verfahren zur Bestimmung der Radon 222 Aktivitätskonzentration in einer Wasserprobe nach der Messung ihrer kurzlebigen Zerfallsprodukte durch direkte Gammaspektro¬metrie der Wasserprobe fest (siehe Anhang A).
Die Radon 222 Aktivitätskonzentrationen, die mit diesem Verfahren unter Verwendung derzeit verfügbarer Gammastrahleninstrumente gemessen werden können, reichen von wenigen Becquerel je Liter bis zu mehreren hunderttausend Becquerel je Liter für eine 1 l Analysenprobe.
Dieses Prüfverfahren kann erfolgreich bei Trinkwasserproben eingesetzt werden. Das Labor ist dafür verantwortlich, die Gültigkeit dieses Prüfverfahrens für Wasserproben ungeprüfter Matrizen sicherzustellen.
Anhang B enthält Angaben zu den erforderlichen Zählbedingungen, um die für die Trinkwasser-überwachung erforderliche Empfindlichkeit zu erreichen.
Qualité de l'eau - Radon 222 - Partie 2: Méthode d'essai par spectrométrie gamma (ISO 13164-2:2013)
L'ISO 13164-2:2013 spécifie une méthode d'essai pour déterminer l'activité volumique du radon 222 dans un échantillon d'eau par la mesure des descendants à vie courte du radon 222 par spectrométrie gamma directe de l'échantillon.
Les valeurs d'activité volumique du radon 222, qui peuvent être mesurées par cette méthode d'essai à l'aide d'instruments à spectrométrie gamma actuellement disponibles, sont comprises entre quelques becquerels par litre et plusieurs centaines de milliers de becquerels par litre pour un échantillon d'essai de 1 l.
Cette méthode d'essai peut être utilisée avec succès sur des échantillons d'eau potable. Il appartient au laboratoire de garantir la validité de cette méthode d'essai pour des échantillons d'eau provenant de matrices non soumises à essai.
Une annexe donne une indication sur les conditions de comptage nécessaires pour obtenir la sensibilité requise pour la surveillance de l'eau potable.

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.
