Soils and rocks are the predominant source of indoor radon (Rn) in sou
thern Belgium. We have studied the correlations between geological fea
tures and indoor Rn concentrations using an indoor Rn data set of appr
ox. 1700 short-term measurements. The sediments in the study region ar
e divided into 11 geological series or 43 stages and 16 rock types. Th
e results show a striking relation between indoor Rn concentration and
the geological factors. (C) 1998 Elsevier Science B.V. All rights res
