Water quality. Radium-226 - Test method using coprecipitation and gamma-spectrometry Ingestion-build-143074 Physiological basis for defining nanoparticles1 Scope This part of ISO 13165 specifies the determination of radium 226 (226Ra) activity concentration in all types of water by coprecipitation followed by gamma spectrometry (see ISO 185893). The method described is suitable for determination of soluble 226Ra activity concentrations greater than 0,02 Bq l1 using a sample volume of 1 l to 100 l of any water type. For water samples smaller than a volume of 1 l, direct gamma spectrometry can be
