Radon is the second leading cause of lung cancer in the United States. A radon reduction system (radon mitigation) reduces high levels of indoor radon to acceptable levels. The system most frequently used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside. This publication educated homeowners on what they should do before, during and after a radon mitigation and what they should expect from a radon mitigator.

The benefits of building a radon-resistant home are that it reduces a family’s risk of lung cancer; it’s easier and less costly to include features during construction; features are incorporated into the home design and improve aesthetics compared to installing a radon mitigation system after construction; it will improve the indoor air quality and reduce moisture levels; a passive system is easy to activate if needed; and it may add to the resale value of your home.

Radon may be found in one out of every 15 homes and is the second leading cause of lung cancer in the United States. This gas can enter your home through cracks and holes in the foundation, or even underground well water. This publication provides information on radon-induced lung cancer and ways to reduce elevated radon inside your home. For more information on radon, visit ugaradon.edu.

Radon in Your Water
Radon is a naturally occurring, radioactive gas formed from the decay of uranium and radium found in geologic deposits. Exposure to radon gas most commonly occurs through elevated levels in home air. However, in Georgia and neighboring states there is a lesser, though still significant, risk of exposure to radon dissolved in drinking water. This circular addresses the issues on its occurrence, human exposure pathways, testing, interpretations, and remediation strategies.
