Water quality. Gross beta activity. Test method using thick source Ingestion-build-89079 BS EN 61158-5-8 specifies the1 Scope This document specifies a test method for the determination of gross beta activity concentration in non saline waters. The method covers non volatile radionuclides with maximum beta energies 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 not be included in the gross beta quantification using
