NGU Riscos Geológicos - Susceptibilidade ao radão em algumas partes da Noruega
A NGU em cooperação com a Autoridade Norueguesa de Protecção contra a radiação desenvolveu uma série de mapas de susceptibilidade ao radão na Noruega, em 2006. Esses mapas fornecem às autoridades locais, informações importantes sobre a distribuição espacial dos potenciais riscos associados ao radão que podem ser usados para definir prioridades na medição de radão. O serviço Web foi originado a partir de quatro mapas impressos de susceptibilidade ao radão na região de Oslo à escala 1:1 000 000.
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.
