The Geological Survey of Norway (NGU) and Norwegian Radiation Protection Authority (NRPA) launched the Radon Susceptibilities Map series in 2006. These maps provide local authorities with important information on the spatial distribution of potential radon hazards, and can be used for determining the priorities for radon measurements in existing dwellings and for evaluating the risks from radon involved in development of new areas. The sources for the radon susceptibility web service are 4 printed maps of the Oslo region at a scale of 1:100 000 available on the NGU website (www.ngu.no).
