BS EN ISO 11704:2015

This standard BS EN ISO 11704:2015 Water quality. Measurement of gross alpha and beta activity concentration in non-saline water. Liquid scintillation counting method is classified in these ICS categories:

• 13.060.60 Examination of physical properties of water
• 17.240 Radiation measurements

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.
