Radon is the second-leading cause of lung cancer in the United States, behind smoking, according to the Environmental Protection Agency. The EPA estimates radon is responsible for about 21,000 lung cancer deaths each year. In Pennsylvania, approximately 40 percent of homes are believed to have radon levels above the EPA’s recommended action level of 4.0 picocuries per liter.

Due to Pennsylvania’s geology, elevated radon levels are common throughout the state, and officials say the only way to determine if a home has a radon problem is through testing. DEP recommends that all homes, schools and buildings be tested, particularly during colder months when buildings are sealed and radon levels are more likely to accumulate.

Radon test kits are available at many home improvement and hardware stores and through Pennsylvania-certified radon laboratories, typically costing between $20 and $30. Completed kits are mailed to certified labs for analysis, with results sent directly to the property owner. Homeowners may also choose to hire a state-certified radon testing company. Even homes with mitigation systems are advised to test every two years.

If elevated radon levels are found, permanent mitigation systems are available and generally cost between $800 and $1,200, with minimal ongoing maintenance required. Lists of state-certified radon contractors, testers and laboratories are available through the DEP.

Residents seeking assistance with test results or next steps can contact DEP’s Radon Division or the Radon Hotline for additional guidance.
