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.
波兰核子反应堆中心(POLATOM)与波兰各医院的核医学科室共同组织了一次关于(90)钇和(89)锶活度测量的能力验证测试。本次测试中使用的放射性溶液通过采用波兰放射性核素活度国家标准测量系统的TDCR方法进行了标准化。根据ISO/IEC 17043:2010(ISO,2010),通过计算z分数和ζ(zeta)分数对结果进行了分析。参与者的整体表现差异显著。误差来源似乎是活度测定过程中使用的校准因子值以及参与者对不确定度的低估。
