520	|a"Estimating indoor radon variations using regional geoscience data for southwestern Ontario generally shows a progressive and clearly positive association. Uranium concentrations measured by airborne gamma ray spectrometry show the strongest positive association with elevated indoor radon concentrations followed by estimated radon potential derived from regional bedrock geology. Comparisons between relative permeability derived from regional surficial geology and indoor radon concentrations were inconclusive. Closer examination suggests that this may not always be the case and that permeability is still an important factor at local scales"--Abstract, page 1.
