Abstract: Energy-efficient building refurbishment has the aim of saving energy and thus reducing CO2 emissions. Increased energy efficiency of a building often implies reduced air exchange. Together with other indoor air quality problems, this may lead to an increase in indoor radon concentration (Rn-222). In order to investigate the extent of this problem, measurements of radon concentration in energy-efficient refurbished and low-energy houses (passive houses) were carried out. Track etch detectors were exposed in each type of building over a period of...
