Summary

For the first time a comparison for the radon activity concentration has been performed within the scope of Euromet. In the project 657 ‘Comparison of calibration facilities for the radon activity concentration’ 12 participants from 9 countries compared different radon reference atmospheres at 1 kBq/m3, 3 kBq/m3 and 10 kBq/m3 via a transfer standard. The comparison was listed as BIPM supplementary comparison. The results of the most participants are correlated due to a common traceability to one single radon gas standard producer. This makes a careful correlation analysis necessary to achieve the comparison reference value. The results of the comparison as well as the complex analysis of the correlated set of data is presented and discussed.
