Sammanfattning

In radiochemical analysis of decommissioning waste, reference materials are not commercially available and consequently intercomparison exercises are needed for method validations. This paper reports the results from an intercomparison exercise focusing on analyses of alpha-emitter radionuclides in spent ion exchange resin. The exercise and statistical analysis of the submitted results were carried out based on ISO 13528 standard according to which the assigned values were calculated from the participant's results and the performances were assessed using z-scores, which showed excellent performance for all Am-241 analyses, good performance for Pu-238 analyses, tolerable performance for Pu-239,Pu-240 analyses, and questionable Cm-243,Cm-244 analyses.
