Summary:Soil gas radon concentrations of 0.5 to 400 kBq.m3 were measured in the urban area of Castelo Branco. At 0.8 meters depth the mean values of the dominant lithologies were as follows: 15 in pre-Ordovician schists and graywackes; 19 in Ordovician quartzites and schists; and 26 in granites. In addition, concentrations above the mean for each of these lithologies were observed along some faults that crosscut them. Radon potential was classified as low to moderate in most parts of this area, and high in the vicinity of some U-rich faults.
