Evaluation of the 2016 ENV57 MetroERM measurement comparison on 137Cs, 134Cs and 131I in air filters
In 2016, the European Commission’s Joint Research Centre organized an interlaboratory comparison exercise on the measurement of 137Cs, 134Cs and 131I in air filters. The exercise was conducted in the frame of the MetroERM EMRP project with code ENV57.
This paper describes the context of the interlaboratory measurement comparison, the technical implementation, the air filter measurements performed by the participating laboratories and finally the evaluation of the comparison results. The intercomparison exercise results are such that 56 out of the 67 laboratories (i.e. 84%) reported values within the ±20% range of the reference value for both the 137Cs and 134Cs. The evaluation of the performance of the laboratories on 131I was complicated and the details are explained. Nevertheless, 20 (30%) laboratories reported results for 131I with a percentage difference from the reference value within the ±20% range.
