Radon in the Home
Radon is an odorless, invisible, radioactive gas that can enter your home from the ground through cracks in the foundation. A known human carcinogen, radon is the second leading cause of lung cancer.
Pennsylvania has one of the most serious radon problems in the United States. Approximately 40 percent of Pennsylvania homes have radon levels above Environmental Protection Agency's action guideline of 4 picocuries per liter.
You can search for radon test data by zip code, but hands down, the smartest thing to do is to test your home for radon, no matter where you live. Protect yourself and your loved ones: Do a home radon test.

Testing Your Home is Easy
Testing is the only way to know if your home has elevated levels of radon. An easy home test kit can be purchased at hardware or home improvement stores for about $20 to $30. You may also hire a state-certified testing company. Because radon levels are often highest in the basement, placing your test there is a good idea. However, radon levels can also be high above ground, even in homes without basements, so the ground floor is also a good location to test.
