NGU Aléas - Cartes de susceptibilité du radon en Norvège
Le Service Géologique de Norvège (NGU) et l'Autorité Norvégienne de Protection des Radiations (NRPA) ont lancé la création de séries de cartes de susceptibilité du radon en Norvège en 2008. Ces cartes fournissent aux autorités locales une information importante sur la distribution spatialme du potentiel des aléas liés au radonet peuvent être utilisées pour définir les priorités de mesure du radon dans les habitations existentes et pour évaluer le futur développement de nouvelles zones. La source pour le web service diffusant la carte de susceptibilité du radon sont 4 cartes imprimées de la région d'Oslo à 1/1M
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.
