Abstract Results of 128 radon screening tests performed by homeowners living in Jackson County, Missouri, and Johnson County, Kansas, are compared to four geologic variables. Slightly higher radon levels are associated with gray shale bedrock and loess-derived soil, but no statistically-significant relationships are found between radon screening levels and bedrock types, soil parent or soil permeability. Previous emphasis on black shales as a principal source of radon precursors in the Kansas City area is unwarranted. The single significant relationship found in this study is that homes built on slopes do possess statistically-higher radon screening levels than those built in upland areas.
