NGU Geološke nevarnosti - Nevarnost radona v delih Norveške
Norveški geološki zavod (NGU) in Norveški urad za zaščito pred radioaktivnim sevanjem (NRPA) sta izdala serijo kart nevarnosti radona leta 2006. Te karte dajejo lokalnim oblastem pomembne podatke o prostorski razporeditvi potencialne nevarnosti radona in jih lahko upoštevajo pri ukrepih zaščite pred radonom v obstoječih bivališčih in pri načrtovanju razvoja novih naselij. Vir medmrežni bazi podatkov o nevarnosti radona so 4 natisnjene karte območja Osla v merilu 1:100 000, ki so dostopne na internetni strani NGU (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.
