Radon zones in Virginia
Last updated
EPA’s Map of Radon Zones places 133 Virginia counties in its three radon potential zones: 65 in Zone 1 (highest), 29 in Zone 2 (moderate), and 39 in Zone 3 (low).
What this means for Virginia homes
Most Virginia counties fall in Zone 1. EPA predicts average indoor screening levels above 4 pCi/L across much of Virginia, so elevated radon is common. Testing is especially worthwhile here, and radon-resistant construction features make sense for new homes.
EPA’s guidance is the same everywhere: test your home, fix it if the level is 4 pCi/L or higher, and consider fixing between 2 and 4 pCi/L. The zone map is from 1993 and should not be used to decide whether a single home needs testing.
Virginia radon program
EPA lists the following state contact for Virginia: Virginia Department of Health, Office of Radiological Health, phone 804-864-8161. Website: www.vdh.virginia.gov/radiological-health/indoor-radon-program. State programs can tell you about local testing data, free or discounted test kits, disclosure rules for home sales, and credentialed radon professionals.
