Technical factors of quality management in gamma-ray spectrometry of environmental samples

The establishment of a quality management system is the best way to comply with international requirements concerning the achievement of confident and traceable analytical results. Some important points dealing with the techn ical factors of quality management in gamma-ray spectrometry of environment al samples are discussed. The experience obtained from analytical procedure validation is presented. Results of the application of standardized proced ures to the analysis of ALMERA intercomparison samples, as well as the outc ome of the utilization of certified reference materials for the quality con trol of measurement are presented. In fact, the implantation of simple tech nical principles reports reliable results and allows to elevate the quality of the measurements at a cost relatively low according to the real possibi lities of the small laboratories, even in developing countries.
