RS ISO 9697: 2018
Water quality — Gross beta activity — Test method using thick source
Abstract

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.
