Abstract: A comparison was conducted, between 11 European National Metrology Institutes and EC-JRC, on measurement of 137Cs activity concentration in fume dust. As comparison material an activity standard produced from real contaminated fume dust was used. The standard material consisted of 13 samples of compressed fume dust, each of 50 g mass and of well-defined cylindrical geometry (diameter 69.5 mm and height 18.7 mm). The material contained 137Cs and 60Co of reference activity concentrations of (9.72 ± 0.10) Bq/g and (0.450 ± 0.018) Bq/g, respectively, determined using the comparison results. The organisation and results of the intercomparison, as well as the process of obtaining reliable reference values are presented.
