Water quality - Radon-222 - Part 4: Test method using two-phase liquid scintillation counting (ISO 13164-4:2015)

ISO 13164-4:2015 describes a test method for the determination of radon-222 (222Rn) activity concentration in non-saline waters by extraction and liquid scintillation counting.
The radon-222 activity concentrations, which can be measured by this test method utilizing currently available instruments, are at least above 0,5 Bq l−1 for a 10 ml test sample and a measuring time of 1 h.
This test method can be used successfully with drinking water samples and it is the responsibility of the laboratory to ensure the validity of this test method for water samples of untested matrices.
Annex A gives indication on the necessary counting conditions to meet the required detection limits for drinking water monitoring.

Wasserbeschaffenheit - Radon-222 - Teil 4: Verfahren mittels zweistufiger Flüssigszintillationszählung (ISO 13164-4:2015)

Dieser Teil von ISO 13164 beschreibt ein Verfahren zur Bestimmung der Aktivitätskonzentration von Radon 222 (222Rn) in nicht salzhaltigen Gewässern durch Extraktion und Flüssigszintillationszählverfahren.
Die Radon 222 Aktivitätskonzentrationen, die mit diesem Verfahren unter Verwendung derzeit verfügbarer Instrumente gemessen werden können, liegen mindestens über 0,5 Bq l−1 für eine 10 ml Analysenprobe und einen Messzeitraum von 1 h.
Dieses Verfahren kann mit Trinkwasserproben erfolgreich angewendet werden, und es liegt in der Verantwortung des Labors, die Gültigkeit dieses Verfahrens für Wasserproben nicht geprüfter Matrizen sicherzustellen.
Anhang A enthält Angaben zu den erforderlichen Zählbedingungen, um die für die Trinkwasserüberwachung erforderlichen Nachweisgrenzen zu erreichen.

Qualité de l’eau - Radon 222 - Partie 4: Méthode d’essai par comptage des scintillations en Milieu liquide à deux phases (ISO 13164-4:2015)

L'ISO 13164-4:2015 spécifie une méthode d'essai permettant de déterminer l'activité volumique du radon 222 (222Ra) dans des eaux non salines par extraction et comptage des scintillations en milieu liquide.
Les valeurs d'activité volumique du radon 222 qui peuvent être mesurées par cette méthode d'essai à l'aide d'instruments actuellement disponibles, sont au moins supérieures à 0,5 Bq l−1 pour une prise d'essai de 10 ml et un temps de comptage de 1 h.
Cette méthode d'essai peut être utilisée avec succès sur des échantillons d'eau potable et il appartient au laboratoire de s'assurer de la validité de cette méthode d'essai pour des échantillons d'eau provenant de matrices non testées.
L'Annexe A donne une indication sur les conditions de comptage nécessaires pour obtenir les limites de détection requises pour la surveillance de l'eau potable.

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
