Annex A (informative) - Example of a carrier solution which
        can be added to the water sample when waste water
        from a nuclear power plant is investigated
Annex B (informative) - Calculation of the activity
        concentration from a gamma spectrum using a

Bibliography

Describes a method for the simultaneous determination of the activity concentration of various radionuclides emitting gamma rays with energies 40 keV < E < 2 MeV in water samples, by gamma-ray spectrometry using germanium detectors with high energy resolution in combination with a multichannel analyser.
