Scope

The method is based on acidifying the sample to stabilize it, evaporation almost to dryness, conversion to the sulfate form and ignition at 350 °C, transfer of a portion of the residue to a planchette and counting beta-activity in a Geiger counting assembly. Covers non-volatile beta-active radionuclides with maximum beta energies higher than 0,3 MeV. Applies to the analysis of raw and potable waters.
