Radon test results can feel like a waiting game, but opening that envelope is simple and crucial for your home's safety. The numbers show radon levels in picocuries per liter. If they're below 2, your home is in a safe range. Between 2 and 4 it's a concern, and above 4 it's time to call a professional for mitigation. It's a small investment that could make a big difference, especially if you have a basement or crawl space.
