Abstract [en]

High radon concentration in drilled wells contributes to an increased risk of radiation and is therefore a health threat. This preliminary study focuses on 1,460-drilled wells in Stockholm County in Sweden and involves the use of GIS to investigate the infl uence of soil, bedrock, fracture zone, elevation, landuse and slope of a terrain on the radon content in drilled wells at a regional level. Statistical analyses of data were performed, using Kruskal-Wallis ANOVA by ranks and the multivariate statistical method of Principal Component Analysis (PCA). The project has so far shown that 8% of analysed wells exceed the Swedish regulatory limit of 1000 Bq/l while 26% of the 1460 wells have a radon concentration greater than 500 Bq/l. In addition it was found that bedrock, topography and the use of the well clearly affect the radon content.
