    Abstract - (Show below) - (Hide below)

    Defines a method for the determination of gross alpha and gross beta activity in waters for radionuclides, which are not volatile at 80 Degrees C.

    Scope - (Show below) - (Hide below)

    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.
