NGU Georisiken - Radon-Anfälligkeit in Teilen von Norwegen
Der Geologische Dienst von Norwegen (NGU) und das Norwegische Strahlungsschutz Amt (NRPA) haben im Jahr 2006 mit der publikation von Radon-Anfälligkeits-Karten begonnen. Diese Karten liefern lokalen Amtsträgern wichtige Informationen zu der räumlichen Ausbreitung von potentiellen Radon Risikos. Desweiteren können diese Karten für die Festlegung von weiteren Radon Messungen in existierenden Bohrungen und bei regionaler Raumplanung hinzugezogen werden.
Der Web-Dienst zur Radon-Anfälligkeit basiert auf 4 gedruckten Karten der Oslo-Region im Maßstab 1 : 100 000. Diese Karten sind ebenfalls über die NGU-Internetseite (www.ngu.no) verfügbar.
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.
