IMPORTANT— It is absolutely essential that tests conducted according to this document be
carried out by suitably trained staff.
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.
