摘要：
Proficiency tests established by ISO/IEC-43 were applied to assess the performance of 69 Brazilian nuclear medicine services in the radiopharmaceuticals activity measurements of (131)I, (99)Tc(m), (67)Ga and (201)Tl. The 214 datasets originated from comparison programs promoted by the Laboratrio Nacional de Metrologia das Radia double dagger es 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 "Not-acceptable" accordingly and have shown a large dispersion when the statistical criteria assays were applied and also compared with regulatory requirements.
