Water quality — Radium 226 and Radium 228 — Test method using liquid scintillation counting
Abstract

This document specifies the determination of radium-226 (226Ra) and radium-228 (228Ra) activity
concentrations in drinking water samples by chemical separation of radium and its measurement using
liquid scintillation counting.
Massic activity concentrations of 226Ra and 228Ra which can be measured by this test method utilizing
currently available liquid scintillation counters go down to 0,01 Bq/kg for 226Ra and 0,06 Bq/kg for
228Ra for a 0,5 kg sample mass and a 1 h counting time in a low background liquid scintillation counter[8].
The test method can be used for the fast detection of contamination of drinking water by radium in
emergency situations.
