Radon is a natural gas that comes up from the soil. You cannot see or smell it, and it is the second leading cause of lung cancer in the United States.
Levels vary house to house, even on the same street, so the only way to know is to test.
We use a continuous monitor that records levels every hour for at least 48 hours, which is more reliable than a single charcoal canister.
If levels are high, a mitigation system usually solves it in a day. Many buyers ask the seller to install one before closing.
