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