Water quality - Gross beta activity - Test method using thick source (ISO 9697:2018)
This document specifies a test method for the determination of gross beta activity concentration in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies of approximately 0,3 MeV or higher. Measurement of low energy beta emitters (e.g. 3H, 228Ra, 210Pb, 14C, 35S and 241Pu) and some gaseous or volatile radionuclides (e.g. radon and radioiodine) might not be included in the gross beta quantification using the test method described in this document.
This test method is applicable to the analysis of raw and drinking waters. The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter used.
It is the laboratory's responsibility to ensure the suitability of this method for the water samples tested.
Wasserbeschaffenheit - Gesamt-Beta-Aktivität - Dickschichtverfahren (ISO 9697:2018)
Dieses Dokument legt ein Verfahren zur Bestimmung der Gesamt-Beta-Aktivität in salzarmem Wasser fest. Dieses Verfahren deckt nichtflüchtige Radionuklide mit einer maximalen Beta-Energie von etwa 0,3 MeV oder mehr ab. Die Messung von Beta-Strahlern mit sehr geringer Energie (z. B. 3H, 228Ra, 210Pb, 14C, 35S und 241Pu) sowie gasförmiger und flüchtiger Radionuklide (z. B. Radon und radioaktives Iod) ist nicht Bestandteil der Gesamt-Betastrahlen-Messung nach dem Verfahren dieses Dokuments.
Das Verfahren ist auf die Analyse von Roh- und Trinkwasser anwendbar. Der Einsatzbereich hängt von der Menge löslicher Salze im Wasser und von der Leistungsfähigkeit (Untergrundzählrate und Zählausbeute) des verwendeten Zählers ab.
Es liegt in der Verantwortung des Labors sicherzustellen, dass das Verfahren für die zu messenden Wasserproben geeignet ist.
Qualité de l'eau - Activité bêta globale - Méthode d'essai par source épaisse (ISO 9697:2018)
Le présent document spécifie une méthode d'essai permettant de déterminer l'activité volumique bêta globale des eaux non salines. La méthode couvre les radionucléides non volatils émetteurs bêta avec des énergies maximales d'environ 0,3 MeV ou plus élevées. Les mesurages des émetteurs bêta à faible énergie (par exemple, 3H, 228Ra, 210Pb, 14C, 35S et 241Pu) et de certains radionucléides gazeux ou volatils (par exemple, radon et iode radioactif) peuvent ne pas être inclus dans la quantification bêta globale en utilisant la méthode d'essai décrite dans le présent document.
Cette méthode d'essai est applicable à l'analyse des eaux brutes et potables. La gamme d'application dépend de la quantité de sels solubles totaux dans l'eau et des caractéristiques de performance (taux de comptage du bruit de fond et efficacité de comptage) du compteur utilisé.
Il incombe au laboratoire de s'assurer que cette méthode est adaptée aux échantillons d'eau soumis à essai.
Kakovost vode - Skupna beta aktivnost - Preskusna metoda robustnega vira (ISO 9697:2018)
Ta dokument določa preskusno metodo za določevanje koncentracije skupne beta aktivnosti v neslanih vodah. Metoda zajema nehlapne radionuklide z največjo beta energijo približno 0,3 MeV ali višjo. Merjenje beta oddajnikov z nizko energijo (npr. 3H, 228Ra, 210Pb, 14C, 35S in 241Pu) ter nekaterih radionuklidov v plinastem stanju oziroma hlapnih radionuklidov (npr. radon in radioaktivni jod) morda ne bo vključeno v kvantifikaciji skupne beta aktivnosti z uporabo metode, opisane v tem dokumentu.
Ta metoda se uporablja za analizo neobdelane in pitne vode. Območje uporabe je odvisno od količine skupnih vodotopnih soli v vodi in od lastnosti uporabljenega števca (stopnja štetja v ozadju in učinkovitost štetja).
Laboratorij mora zagotoviti primernost te metode za vzorce vode, ki se preskušajo.

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.
