Beschreibungen/Notizen

• Measurements were made using the TDCR method. POLATOM prepared and distributed for the key comparison participants the 55 Fe solution and 55 Fe ready-to-measure sources in the Ultima Gold™ scintillator in polyethylene vials. The stability of the sources was confirmed. Source counting efficiency decreased proportionally with time by about 0.7% per month, possibly due to colour quenching. The POLATOM measurement result was consistent with the key comparison reference value. The nuclear data for 55 Fe were adopted in accordance with the KCWG(II) recommendation. Measurement results obtained in non-diffusive (glass) vials were lower than in diffusive vials.
