NGU Geohazards - Radon susceptibility in parts of Norway
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).
1G-E:percentCoverage=100 of the Oslo Region; 1G-E:geometricHarmonization=yes; 1G-E:thematicHarmonization=yes; In constructing radon awareness maps, NGU measured uranium concentrations in the ground using instruments mounted in helicopters and airplanes. The NRPA contributed measurements of indoor radon in 6326 dwellings within the study area. Comparison of these data sets, and incorporation of information on bedrock and drift geology, resulted in radon awareness maps covering some 10,000 square kilometres from Hadeland and Romerike in the North to Fredrikstad and Skien in the South. Almost two million people reside in this area. The source for the radon susceptibility web service are 4 printed maps of the Oslo region in scale 1:100 000.
