标准范围
This International Standard specifies a test method for the determination of gross beta activityconcentration in non-saline waters. The method covers non-volatile radionuclides with maximum betaenergies of approximately 0,3 MeV or higher. Measurement of low energy beta emitters (e.g. 3H, 228Ra,210Pb, 14C, 35S, and 241Pu) and some gaseous or volatile radionuclides (e.g. radon and radioiodine) might notbe included in the gross beta quantification using the test method described in this International Standard.This test method is applicable to the analysis of raw and drinking waters. The range of applicationdepends on the amount of total soluble salts in the water and on the performance characteristics(background count rate and counting efficiency) of the counter used.It is the laboratory’s responsibility to ensure the suitability of this method for the water samples tested.
