## What the source says

> 17554,IS,,ISO 9698:1989,Water quality — Determination of tritium activity concentration — Liquid scintillation counting method,Qualité de l'eau — Détermination de l'activité volumique du tritium — Méthode par comptage des scintillations en milieu liquide,1989-12-07,1,"['13.060.60','13.280']",ISO/TC 147,9599,,[51944],"['en','fr']",7,<p>The method specified is applicable to all types of water including seawater with concentrations of up to 10 ^ 6 Bq/m ^ 3 when using 20 ml counting vials. The method is not applicable to the analysis of organically bound tritium; its determination requires an oxidative digestion.</p>
