Quality control of gamma-ray spectrometry measurements

Specific techniques have been implemented to assess the quality of routine gamma-ray measurements and the associated analysis procedures. Appropriate steps monitor three factors influencing the quality of performance: the per formance of the spectrometer, the quality of the measurement and the qualit y of the peak analysis. In order to illustrate the approach, time dependenc ies of parameters describing the performance of the spectrometer, the quali ty of the measurements and the sample activities are presented.
