Abstract: This is the final report for the CCRI(II)-K2.Tc-99 key comparison of the activity of the radionuclide 99 Tc per unit mass of aqueous solution which was organised in 2012 by the National Physical Laboratory of the United Kingdom.The Key Comparison Reference Value (KCRV) of 56.45 kBq g -1 with a combined standard uncertainty of 0.13 kBq g -1 was determined from the power-moderated mean of the results of 13 laboratories, with results from a further three laboratories being rejected by the accepted statistical criteria.
