Abstract: The Radioisotope Centre POLATOM organized a proficiency test of activity measurements of (90)Y and (89)Sr with nuclear medicine departments in Polish hospitals. Radioactive solutions used in this exercise were standardized by the TDCR method using the measurement systems of the National Standard of Radionuclides Activity in Poland. Results were analysed in compliance with ISO/IEC 17043:2010 (ISO, 2010) by calculating z scores and ζ (zeta) scores. The overall performance of the participants varied significantly. The sources of errors appeared to be the values of the calibration factor used during activity assay and the underestimation of uncertainties by the participants.<br /> (© 2013 Published by Elsevier Ltd.)
