Supplementary comparison of tube voltage standards for x-ray imaging

In this project nine participating laboratories will perform a comparison in terms of tube voltage for standards used in x-ray imaging measurements. The comparison is performed as a part of EURAMET 22NMR01 TraMeXI project. Four RQR radiation qualities will be used in the comparison and two transfer instruments (x-ray multimeters) will be circulated among the participating laboratories. PTB provides the reference value for the comparison.

The comparison is performed as a part of the EURAMET 22NMR01 TraMeXI project. In this supplementary comparison the responsibilities of a pilot laboratory are shared between STUK (Finland) and VSL (The Netherlands). STUK (as the TraMeXI project coordinator) is the reporting pilot laboratory and responsible for collection of the results and reporting to the EURAMET. VSL (as the TraMeXI leader of the comparison) is the coordinating pilot laboratory and responsible for the organisation of the comparison.
