Bibliography

ISO 10703:2007 specifies a method for the simultaneous determination of the activity concentration of various radionuclides emitting gamma rays with energies between 40 keV and 2 MeV in water samples, by gamma‑ray spectrometry using germanium detectors with high energy resolution in combination with a multichannel analyser.
