High radon in Pennsylvania is a serious concern, as the state sits on uranium-rich geology that releases this radioactive gas into homes. It's the second leading cause of lung cancer, and testing is the only way to know if your house has dangerous levels. Many older homes in the Reading Prong region are especially vulnerable, but newer houses can have issues too. I tested mine last year and was shocked at the reading.
