Overview

This document specifies the determination of radium-226 (226Ra) activity concentration in non-saline water samples by extraction of its daughter radon-222 (222Rn) 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. This method is not applicable to the measurement of other radium isotopes. The responsible national standardization committee is Subcommittee NA 119-01-03-08 UA "Radioaktivitätsmessung im Wasser" ("Radioactivity measurements in waters") at DIN Standards Committee Water Practice (NAW).
