Dangerous Radon Levels in Georgia

What are Dangerous Radon Levels in Georgia?

Understanding Radon Risks and What You Can Do About Them

If you’ve heard about radon but aren’t sure what the numbers mean, you’re not alone. Radon is colorless, odorless, and tasteless—but it’s also the second leading cause of lung cancer in the U.S. after smoking. And in many parts of Georgia, radon levels can quietly rise to dangerous levels inside homes.

So…

What’s considered “safe” and what’s considered “dangerous”?

Let’s break it down.

What Is Radon and Why Does Georgia Need to Pay Attention?

Radon is a radioactive gas that comes from the natural breakdown of uranium in soil and rock. It seeps up through the ground and can accumulate in enclosed spaces—especially basements and crawlspaces.

In Georgia, especially in northern counties like Fulton, Cobb, and Gwinnett, radon levels can be moderate to high due to soil composition.

What are dangerous Radon Levels in georgia?

The EPA action level for radon is 4.0 picocuries per liter (pCi/L).

• 0–1.9 pCi/L: Low risk
• 2.0–3.9 pCi/L: Moderate—consider mitigation if prolonged exposure
• 4.0+ pCi/L: High—strongly recommended to take action

Even levels between 2 and 4 pCi/L may pose a health risk with long-term exposure, especially for children, smokers, or people with respiratory issues.

The World Health Organization (WHO) actually recommends mitigating at 2.7 pCi/L—lower than the U.S. EPA threshold.

What If You Live in Georgia?

You live in one of the EPA’s designated “Zone 1” or “Zone 2” counties, which means your risk is elevated. Many homes in Metro Atlanta test well over 4.0 pCi/L without the homeowners ever knowing.

Georgia counties with consistently high radon levels include:

• Cobb County
• Fulton County
• Cherokee County
• DeKalb County
• Hall County

ALERT: If you live in North Georgia, there’s a good chance your home is at risk.

How Do You Know Your Home’s Radon Level?

You have two choices:

1. DIY radon test kits – inexpensive but prone to error and limited accuracy
2. Professional testing – accurate, EPA-approved equipment with fast results

We recommend professional testing for homeowners, real estate transactions, or anyone concerned about air quality.
