Radon Potential map
The Radon Potential of Rocks and Soil in Fairfax County, Virginia, Button, James K, et al., 1988. Short-term test results from a study conducted by the Fairfax County Health Department during the winters of 1986-87 and 1987-88 found that radon levels above the U.S. Environmental Protection Agency action level of 4 picoCuries per liter of air can occur anywhere in the areas shown on the map. In the areas of LOW potential (yellow), 14% of the homes tested had radon levels that were a problem. At the other end of the radon range, 56% of the homes tested in the areas of HIGH potential (red ) did not have problem radon levels.
