RADON: The Department of Environmental Protection is encouraging Pennsylvanians to start off the new year by conducting a simple test of their homes for radon, a naturally occurring radioactive gas that is the second leading cause of lung cancer.

Winter is a good time to test because doors and windows are closed, providing more accurate results.

“Because of our geology, nearly every county in the commonwealth has locations of high radon levels, putting Pennsylvanians at risk of exposure,” said DEP Secretary Patrick McDonnell. “A radon test is a great way to protect yourself and your family. Fortunately, testing your home for radon is as simple as opening a can, and inexpensive do-it-yourself tests are available at hardware and home stores.”

Radon is an odorless, colorless, radioactive gas that occurs from the breakdown of uranium in the ground. It enters homes through cracks in the foundation or other openings. As a result, high levels of radon tend to be found in basements, but the gas can be found anywhere in the home.

“Radon is a leading cause of lung cancer in Pennsylvania,” Health Secretary Dr. Rachel Levine said. “Since we know that radon is prevalent in homes across Pennsylvania, it is important to test your home. It is a simple step you can take to protect your family’s health.”

The U.S. Environmental Protection Agency (EPA) has set 4 picocuries of radon per liter (pCi/L) of air as an Action Level. If your radon level is higher than this, EPA, DEP, and the U.S. Surgeon General recommend having a radon mitigation system professionally installed to lower it. Typically consisting of a pipe and exhaust fan, the system will vent radon to the outside.

DEP will send free follow-up test kits to Pennsylvanians who’ve tested their homes and have results higher than 100 pCi/L or who’ve installed an active mitigation system in the past year.
