1 Scope This document specifies the determination of radium-226 ( 226 Ra) activity concentration in non-saline water samples by extraction of its daughter radon-222 ( 222 Rn) and its measurement using liquid scintillation analysis. The test method described in this document, using currently available scintillation counters, has a detection limit of approximately 50 mBq·l −1 . This method is not applicable to the measurement of other radium isotopes.
