ISO 9698:2019

Water quality - Tritium - Test method using liquid scintillation counting

PUBLISH DATE 2019
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.
