preparation of control cards for two chains of gamma spectrometry

The objective of this study is to achieve quality control of gamma spectrometry in the laboratory using Radio analyse card checks. The interpretations of these maps show that the two gamma spectrometry detectors present many anomalies. The results showed that the problems from either the gamma spectrometry chain or the external environment which requires developing a set of some preventive solutions that will accompany each calibration.
