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.
