If you get your water from a private well, radon can build up inside as it seeps in from surrounding rocks. You can't see or smell it, but breathing it while showering or doing laundry can raise your lung cancer risk over time. Testing is the only way to know your levels, and if they're high, a simple aeration treatment can help remove it.
