Zusammenfassung	This is the final report for the CCRI(II)-K2.Tc-99 key comparison of the activity of the radionuclide ⁹⁹Tc 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.
