Abstract
The Environmental Radiometry Laboratory (LRA in Spanish) has participated in proficiency tests carried out by the International Atomic Energy Agency (IAEA) since 2015, as part of its analytical quality assurance process. This work presents the results obtained by the LRA using the gamma ray spectrometry technique during his six years of participation, differentiating them according to type of sample and analyzed radionuclides. The description of the qualification criteria of the proficiency tests between laboratories and their relationship with the validation of the method is presented, as well as the improvements implemented to guarantee the validity of the results.
