Description
An international Key Comparison of 177Lu has recently been carried out. Twelve laboratories performed assays for radioactivity content on aliquots of a common master solution of 177Lu, leading to eleven results submitted for entry into the Key Comparison Database of the Mutual Recognition Arrangement. A proposed Comparison Reference Value (CRV) was calculated to be 3.288(4) MBq/g using all eleven results. Degrees of equivalence and their uncertainties were calculated for each laboratory based on the CRV. Most of the values reported by the participating laboratories were within 0.6% of the CRV. - Highlights: ► First international Key Comparison of 177Lu has recently been carried out. ► Twelve metrology laboratories took part. ► Proposed Comparison Reference Value (CRV) calculated to be 3.288(5) MBq/g. ► Degrees of equivalence and their uncertainties were calculated. ► Most laboratories' results were within 0.6 % of the CRV.
