Pennsylvania radon action level 7

https://wiki-cable.win/index.php/Why_High_Radon_in_Pennsylvania_Is_a_Problem_You_Can_Fix

Pennsylvania radon action level is set at 4 picocuries per liter, which is the threshold the EPA recommends for fixing your home. It's not just a number; it's a real concern here since our geology can lead to higher readings. If your test shows that level or above, getting a mitigation system is smart—not scary, just practical. I'd suggest testing in the lowest livable area, like a basement, to get an accurate measure.
