This study describes an approach for measuring and modeling diffusive and advective transport of radon through building materials. Goal of these measurements and model calculations is to improve our understanding concerning the factors influencing the transport of radon through building materials. To reach this goal, a number of experiments has to be conducted. These experiments, including measurements in a large cylinder for creating diffusive and advective transport of radon under controlled, dwelling-like conditions, are described here and the initial results are presented.
