TY - JOUR A1 - Hofmann, Michael A1 - Richter, Matthias A1 - Jann, Oliver T1 - Robustness validation of a test procedure for the determination of the radon-222 exhalation rate from construction products in VOC emission test chambers N2 - This study investigated the adaptation of the state-of-the-art test procedure for the determination of emissions of volatile organic compounds (VOC) from materials into indoor air to test for the radon exhalation from stony construction products. A complete robustness validation including all relevant parameters showed that the procedure can be well applied by testing institutes already holding available the required VOC testing infrastructure that solely needs to be complemented by calibrated commercial radon measurement instrumentation. When measurements of the radon exhalation from construction materials become mandatory by law, test capacity can easily be applied. This work can serve as a recommendation for the European standardisation that still is on hold in this point.
