Radon
Guides and answers on radon testing and mitigation for homes and commercial properties.
What this collection covers
Radon is a naturally occurring radioactive gas that moves from soil into buildings through foundation cracks, sump pits, and slab penetrations. Because it is colorless and odorless, the only way to know a building's level is to measure it. The guides below explain how testing works, what the results mean, and the mitigation options available once a level is confirmed.
You might be testing before a real estate closing, following up on an elevated short-term result, or planning a mitigation system. These resources walk through the process step by step. Each guide reflects the EPA action level of 4.0 pCi/L that drives most testing and mitigation decisions across the Southeast.
