DESCRIPTION
UNE EN ISO 13165-1:2024
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"1. This method is not applicable to the measurement of other radium isotopes.
