An international Key Comparison of p>177p>Lu has recently been carried out. Twelve laboratories performed assays for radioactivity content on aliquots of a common master solution of p>177p>Lu, 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.
