  1. Comments on results of the SS1 Stainless Steel measurements Em. Cincu, I. Manea, O. Sima IWIRAD 2005

  2. Purpose: • To present the results obtained by NAA in comparison with “reference” values obtained by other methods => graphs of mean values => Z scores • NAA results: laboratory codes 2 – 5 • Reference results: code 1 IWIRAD 2005

  3. Graphs of mean values • NAA results: mean values with error bars corresponding to the reported uncertainty • Reference results: mean values with error bars corresponding to the standard deviation • 8 elements reported by all NAA participants • 1 element reported only by 3 NAA labs • 2 elements reported only by 2 NAA labs • 2 elements reported only by 1 NAA lab, which are missing from the reference data. IWIRAD 2005
