Radon Levels in the Shenandoah Valley
According to the Virginia Department of Health, approximately 35% of homes in the Shenandoah Valley have radon levels above the EPA’s action level of 4.0 pCi/L, making elevated exposure far more common here than in many parts of the country. In fact, the county’s average radon level sits at 4.5 pCi/L—more than triple the national average of 1.3 pCi/L. Virginia’s unique geology naturally produces increased radon levels statewide. For residents of the Shenandoah Valley, this means that testing your home isn’t just a precaution—it’s a vital step in protecting your household from a proven cause of lung cancer.
What is Radon?
-
Radon is a naturally occurring radioactive gas that seeps into buildings, including homes, schools, and offices, from the ground.
-
It's odorless, colorless, and tasteless— detectable only through testing.
-
Radon is the second leading cause of lung cancer in the U.S., following smoking.
Interpreting Radon
Test Results
-
Below 2.0 pCi/L: Low risk.
-
2.0 – 3.9 pCi/L: Moderate risk; consider mitigation.
-
4.0 pCi/L and above: High risk; mitigation strongly recommended.
What is Radon Mitigation?
-
Radon mitigation involves reducing radon levels in homes.
-
The most common method is sub-slab depressurization, which uses a vent pipe system and fan to draw radon from beneath the house and vent it outside.
-
Sealing cracks and improving ventilation are also effective strategies.

What is Radon?
Radon is a radioactive gas that is naturally released in the air from rocks and soil. Radon is in the air outside and can build up to dangerous or deadly levels inside homes and other buildings.
According to the U.S. Centers for Disease Control & Prevention, there is no known safe level of radon; however, aiming for the lowest achievable radon level in your home will reduce your risk of harmful health effects, primarily, lung cancer.
How do I protect myself and my family from radon?
Radon is the second leading cause of lung cancer. Radon is the number one cause of lung cancer in people who never smoked. For people with a history of smoking, radon exposure can significantly increase their lung cancer risk.
Because radon is colorless and odorless, the only way to know if it’s present is through testing.
The good news? Testing is simple, low-cost, and many states offer resources to help with both testing and fixing high levels, if needed.
Who is Impacted by Lung Cancer?
Diagnosed in 2015, Jackie Nixon first noticed something was wrong when she began struggling to sing. Concerned, she consulted her doctor. That’s when Jackie received a diagnosis that would change her life: lung cancer.
Following her treatment recovery, Jackie dedicated herself to advocating for those impacted by lung cancer, raising awareness of its risk factors, and promoting the importance of early detection and radon mitigation.
