Water quality - Tritium - Test method using liquid scintillation counting (ISO 9698:2019)

This document specifies a method by liquid scintillation counting for the determination of tritium activity concentration in samples of marine waters, surface waters, ground waters, rain waters, drinking waters or of tritiated water ([3H]H2O) in effluents.
The method is not directly applicable to the analysis of organically bound tritium; its determination requires additional chemical processing of the sample (such as chemical oxidation or combustion).
With suitable technical conditions, the detection limit may be as low as 1 Bq·l−1. Tritium activity concentrations below 106 Bq·l−1 can be determined without any sample dilution.

Qualité de l'eau - Tritium - Méthode d'essai par comptage des scintillations en milieu liquide (ISO 9698:2019)

Le présent document spécifie une méthode de détermination de l'activité volumique du tritium dans des échantillons d'eaux de mer, de surface, souterraines et pluviales, d'eaux potables ou d'eau tritiée ([3H]H2O) dans les effluents par comptage des scintillations en milieu liquide.
Cette méthode n'est pas directement applicable à l'analyse du tritium organiquement lié; sa détermination nécessite un traitement chimique supplémentaire de l'échantillon (tel une oxydation chimique ou une combustion).
Dans les conditions techniques adéquates, la limite de détection peut être réduite à 1 Bq·l−1. Les activités volumiques du tritium inférieures à 106 Bq·l−1 peuvent être déterminées sans dilution de l'échantillon.

Kakovost vode - Tritij - Preskusna metoda s štetjem s tekočinskim scintilatorjem (ISO 9698:2019)

Ta dokument določa metodo s štetjem s tekočinskim scintilatorjem za določanje koncentracije tritija v vzorcih morskih voda, površinskih voda, podzemnih voda, deževnice, pitne vode ali vode s tritijem ([3H]H2O) v odpadnih vodah.
Metoda se neposredno ne uporablja za analizo organsko vezanega tritija, ki za določevanje zahteva dodatno kemično predelavo vzorca (na primer kemično oksidacijo ali zgorevanje). Pod primernimi tehničnimi pogoji je lahko meja detekcije nizka, in sicer do 1 Bq·l−1. Koncentracije aktivnosti tritija pod 106 Bq·l−1 je mogoče določiti brez redčenja vzorca.
