Alcance
ISO 9697:2008 specifies a method for the determination of gross beta activity in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies > 0,3 MeV. Measurement of very low energy beta emitters, such as 3H; 14C, 35S and 241Pu, is not included in ISO 9697:2008.The method is applicable to the analysis of raw and potable waters.
