Abstract
Proficiency tests established by ISO/IEC43 were applied to assess the performance of 69 Brazilian nuclear medicine services in the radiopharmaceuticals activity measurements of 131I 99Tcm 67Ga and 201Tl The 214 datasets originated from comparison programs promoted by the Laboratório Nacional de Metrologia das Radiações Ionizantes LNMRI in 2006/2007 were also evaluated against acceptance criteria of ±10 limits for accuracy required by Brazilian regulatory authority The results of performance evaluation were assigned as “Acceptable” or “Notacceptable” accordingly and have shown a large dispersion when the statistical criteria assays were applied and also compared with regulatory requirements
