Abstract

Abstract: In 2014, the Joint Research Centre organised an interlaboratory comparison of 137 Cs measurement in air filters. This paper describes the context of the European measurement comparisons, as well as the technical implementation. Furthermore, sample treatment and measurements performed by participating laboratories are discussed and finally the evaluation of comparison results is presented. The intercomparison results are such that 71 out of the 76 laboratories (i.e. 93.4%) reported values within ±33% range of the reference value. Highlights: 76 participants from Europe in the EC ILC on the determination of 137 Cs in air filters. Spiked air filters prepared individually for each participant. 93.4% of the laboratories reported within ±33% interval of the reference value. 70% of the submitted results are compatible on the basis of the E n numbers. The problems encountered confirm a permanent need for such comparisons.
