Building Safer Homes in Georgia: The Importance of Radon-Resistant New Construction

Radon is a naturally occurring radioactive gas that poses significant health risks, including lung cancer. Alarmingly, in Georgia, radon exposure contributes to approximately 800 deaths annually.

Understanding Georgia's Radon Zones

The Environmental Protection Agency (EPA) classifies Georgia counties into three radon zones, with Zone 1 representing the highest potential for elevated radon levels. Many northern Georgia counties, such as Fulton, Cobb, DeKalb, and Gwinnett, fall under this high-risk category. This underscores the need for proactive measures to reduce radon exposure.

Radon-Resistant New Construction (RRNC): A Proactive Solution

Incorporating Radon-Resistant New Construction (RRNC) techniques during the building phase is a cost-effective strategy for minimizing radon risks. While retrofitting existing homes can cost between $1,200 and $3,000, integrating RRNC features during construction typically costs only $300 to $500.

Key RRNC strategies include:

• Gas-Permeable Layer: A layer beneath the foundation allows soil gases to move freely, preventing radon buildup under the home.

• Plastic Sheeting: Installed over the gas-permeable layer, this acts as a barrier to stop soil gases from entering the home.

• Vent Pipe: A vent pipe extending from the gas-permeable layer to the roof safely vents radon above the house.

• Sealing and Caulking: Sealing openings in the concrete foundation floor reduces radon entry points.

• Junction Box: An electrical junction box for a future vent fan enables easy activation of a passive radon system, if needed.

Enhancing Buyer Confidence

Educating potential buyers about radon risks and the measures taken to mitigate them is crucial. Providing documentation of radon-resistant features and offering resources can reassure buyers and increase the marketability of new homes. For instance, the University of Georgia's Radon Program offers valuable resources and testing kits, empowering residents to make informed decisions about radon safety.

The Importance of Certified Professionals

While Georgia does not mandate certification for radon professionals, working with certified experts ensures proper installation of radon mitigation systems. Certified professionals bring the expertise needed to design and implement effective solutions.

Investing in Public Health and Peace of Mind

Proactively addressing radon risks during construction not only enhances the safety of new homes but also contributes to public health and buyer confidence. Builders who prioritize radon-resistant features demonstrate their commitment to creating healthier, safer living environments in Georgia.
