Improving of quality control and quality assurance in 14C and 3H Laboratory: Participation in the IAEA model project

Users of laboratory analytical results are increasingly requiring demonstrable proofs of the reliability and credibility of the results using internationally accepted standards, because the economic, ecological, medical and legal decisions based on laboratory results need to be accepted nationally and internationally. Credibility, respect and opportunities of the laboratories are improved when objective evidence on the reliability and quality of the results can be given. This is achieved through inculcation of a quality culture through definition of well-defined procedures and controls and operational checks characteristic of quality assurance and quality control (QA/QC). IAEA launched in 1999 a two-and-a-half year model project entitled "Quality Control and Quality Assurance of Nuclear Analytical Techniques" with participation of laboratories using alpha, beta and/or gamma spectrometry from CEE and NIS countries. The project started to introduce and implement QA principles in accordance with the ISO-17025 guide, leading eventually to a level at which the QA system is self-sustainable and might be appropriate for formal accreditation or certification by respective national authorities. Activities within the project consist of semi-annual reports, two training workshops, two inspection visits of the laboratories by IAEA experts and proficiency tests. The following topics were considered: organisation requirements, acceptance criteria and non-conformance management of QC, internal and external method validation, statistical analyses and uncertainty evaluation, standard operation procedures and quality manual documentation. 14C and 3H Laboratory of the Ruđer Bošković Institute has been one of ten laboratories participating in the Project. In the Laboratory all the procedures required in the quality control were included implicitly, while during the Model Project much effort has been devoted to elaboration of explicit documentation. Since the beginning of the Project the 14C and 3H Laboratory showed consecutive progress in most quality indicators.
