DESCRIPTION
20/30397856 DC
This standard 20/30397856 DC BS ISO 13165-1. Water quality. Radium-226 is classified in these ICS categories:
- 13.060.60 Examination of physical properties of water
- 17.240 Radiation measurements
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.
Radium-226 activity concentrations which can be measured by this test method utilizing currently available liquid scintillation analyzers goes down to 50 mBq l−1. This method is not applicable to the measurement of other radium isotopes.
