In northern Virginia, significant indoor radon differences occur between nearby communities. Studies reveal these differences to be correlated with soil chemistry and permeability. Homes constructed in the soil that developed over the Peters Creek Schist almost all exceed the USEPA 's MCL of 2 pCi/L for homeowners, and over 50% exceed the USEPA's MCL of 4 pCi/L for home buyers. In this study group, home construction seems not important except that homes with electrical heating systems averaged almost 2 pCi/L higher that homes with gas an oil furnaces. It was unanticipted that total-gamma radiation in the county soil was not homogeneous, and comparisons between indoor radon and soil radon show a positive correlation, suggesting that soil aeroradioactivity measurements can delineate areas with a high potential for indoor radon.
