Annotation of standard text ČSN EN ISO 13165-1 (757619):

This part of ISO 13165 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 counting. Radium-226 activity concentrations which can be measured by this test method utilizing currently available liquid scintillation counters goes down to 50 mBq l-1. This method is not applicable to the measurement of other radium isotopes
