NS-EN ISO 11704:2015 Water quality — Measurement of gross alpha and beta activity concentration in non-saline water — Liquid scintillation counting method (ISO 11704:2010)
Full Description ADOPTED_FROM:EN ISO 11704:2015 ISO 11704:2010 specifies a method for the determination of gross alpha and gross beta activity in waters for radionuclides which are not volatile at 80 °C. Radon isotopes and their decay products of short half life are not included in the determination. The method is applicable to raw and potable waters with a dry residue less than 5 g/l and when no correction for colour quenching is necessary.
