Radon Health Risks: What Every Georgia Family Should Know

Most people have heard of radon. Far fewer understand just how serious a health threat it represents — or that their own home might be putting their family at risk right now.

Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths every year. That's more than drunk driving, more than house fires, and more than carbon monoxide poisoning combined. Yet the vast majority of American homes have never been tested for radon.

If you live in Georgia — particularly in the northern part of the state — understanding radon health risks isn't just useful information. It could save your life.

Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil, rock, and water. It's colorless, odorless, and tasteless — completely undetectable without specialized equipment.

Radon moves upward through soil and enters homes through:

• Cracks in concrete floors and walls
• Gaps around service pipes and utility penetrations
• Construction joints between the foundation and walls
• Crawl space floors and walls
• Sump pits and floor drains
• Well water (in some cases)

Once inside a home, radon can accumulate to dangerous concentrations, especially in lower levels with limited ventilation. Basements, first floors, and crawl spaces are the areas of greatest concern.

When you breathe air containing radon, you inhale radioactive particles that attach to the lining of your lungs. These particles emit alpha radiation — a type of ionizing radiation that can damage the DNA in lung cells.

Over time, this DNA damage can cause cells to mutate and grow uncontrollably, leading to lung cancer. The risk is cumulative: the higher the radon concentration and the longer the exposure, the greater the risk.

Radon-induced lung cancer typically develops over many years of exposure. This is why the risk is often underestimated — there are no immediate symptoms of radon exposure. By the time lung cancer is diagnosed, the damage has been accumulating for decades.

The combination of radon exposure and cigarette smoking is particularly dangerous. Tobacco smoke damages the cilia in the lungs that normally help clear particles, making it easier for radon decay products to lodge in lung tissue. The EPA estimates that smokers exposed to elevated radon levels have a lung cancer risk roughly 10 times higher than non-smokers at the same radon level.

If you smoke and live in a home with elevated radon, addressing both risks is critical.

Children breathe faster than adults and spend more time at home, which means they may inhale more radon particles per pound of body weight. Their developing cells are also more susceptible to radiation damage. While most radon-related lung cancers develop in adults after decades of exposure, the foundation of that risk is often laid in childhood.

The more time you spend in your home, the greater your cumulative radon exposure. Remote workers, stay-at-home parents, retirees, and anyone who spends significant time in lower levels of the home — basements, finished lower levels — face higher exposure than those who are away from home most of the day.

In Georgia, residents of North Georgia counties — particularly those in the Blue Ridge and Piedmont regions — face elevated radon risk due to the underlying geology. Counties including Cherokee, Pickens, Gilmer, Dawson, Forsyth, Hall, and Lumpkin have higher-than-average radon potential.

The EPA has established an action level of 4 picocuries per liter (pCi/L). At this level or above, the EPA recommends taking action to reduce radon in your home.

To put this in perspective:

• The average indoor radon level in U.S. homes is about 1.3 pCi/L
• The average outdoor level is about 0.4 pCi/L
• At 4 pCi/L, a non-smoker's lifetime risk of lung cancer from radon alone is about 7 in 1,000
• At 20 pCi/L — a level found in some Georgia homes — that risk rises to about 36 in 1,000

The EPA also notes that there is no known safe level of radon exposure. Even levels below 4 pCi/L carry some risk, and reducing your home's radon level — even if it's currently below the action level — is always beneficial.

This is where radon is particularly insidious: there are no symptoms of radon exposure. You cannot feel, smell, or taste radon. You won't experience any immediate health effects from breathing radon-contaminated air.

The only sign of radon-induced lung cancer is lung cancer itself — and by the time symptoms appear (persistent cough, chest pain, shortness of breath, coughing up blood), the disease is often in an advanced stage.

This is why testing is so important. It's the only way to know whether your home has a radon problem.

Testing is the essential first step. You can use a DIY short-term test kit (available at hardware stores for $15–$30) for an initial reading, or hire a certified radon measurement professional for a more accurate, certified result.

At Georgia Radon Pros, our NRPP-certified technicians use continuous electronic monitors that record radon levels every hour throughout the test period. Results are delivered within 48 hours, and we provide a detailed certified report.

If your test results come back at 4 pCi/L or higher, a radon mitigation system can dramatically reduce your exposure. The most common method — sub-slab depressurization — involves installing a pipe and fan system that draws radon from beneath your foundation and vents it safely outside.

A properly installed system can reduce indoor radon levels by 90% or more, often bringing levels well below 2 pCi/L. Most installations are completed in a single day.

Radon levels can change over time as soil conditions, home construction, and ventilation patterns shift. The EPA recommends re-testing your home every two years, and after any major renovation that affects the foundation or lower levels.

If you have a mitigation system installed, re-test every two years to confirm the system is still performing effectively.

If you're buying a home, always request a radon test during the inspection period. If you're selling, consider testing proactively and mitigating before you list — it removes a potential deal-breaker and demonstrates that you've taken your home's health seriously.

Radon is a serious, preventable health risk. It's not a distant, theoretical danger — it's present in homes across Georgia right now, and it's causing real harm to real families.

The good news is that radon is entirely manageable. Testing is affordable and fast. Mitigation is effective and long-lasting. And the peace of mind that comes from knowing your home is safe is priceless.
