Radon

Professional Radon Testing

Radon can be present in any home, regardless of its age, appearance, or foundation type. Because this naturally occurring radioactive gas cannot be seen, smelled, or tasted, testing is the only way to determine the radon level inside a property.

Due to local geology, Georgia has particularly high radon levels, making local testing essential. Home Scan Home Inspections provides professional radon testing in Coweta County, throughout the state of Georgia, and across eastern Alabama. Whether you are buying a home, preparing to sell, or simply want more information about your living environment, we deliver rapid, accurate results to guide your next steps.

What to Expect & Quick 48-Hour Results

We use continuous radon monitors to ensure fast, reliable reporting. Once our equipment is set up on-site, we track conditions over a standard measurement period and retrieve a final reading within 48 hours.

Our process:

1. Selecting an optimal testing location on the lowest liveable level.
2. Positioning equipment according to strict industry standards.
3. Recording ambient testing conditions and ensuring device placement remains undisturbed.
4. Retrieving the monitor and providing clear, prompt results within 48 hours.
5. Explaining what your numbers mean and outlining recommended actions.

Understanding Your Results & Safety Thresholds

Radon levels are measured in picocuries per liter of air (pCi/L).

• 4.0 pCi/L or Lower: Represents the standard threshold for minimal health risk. To maintain no immediate health risk, levels must remain at or below this target.
• 4.0 pCi/L or Higher: The U.S. Environmental Protection Agency (EPA) strongly recommends taking action to reduce radon levels at or above this limit.
• 2.0 to 4.0 pCi/L: Because no exposure level is completely risk-free, the EPA suggests considering mitigation even in this borderline range.

If an elevated result is found, a certified radon mitigation professional can install a venting system to pull radon from beneath the home and safely direct it outdoors. A follow-up test is then performed to ensure levels drop safely to 4.0 pCi/L or below.

Home Scan provides comprehensive radon testing and detailed reports. If mitigation is required, we can point you toward qualified local mitigation specialists.

What Is Radon?

Radon is a radioactive gas produced as natural uranium breaks down in soil and rock. It moves through the ground and enters buildings through openings around the foundation, floor drains, construction joints, sump pits, and gaps surrounding utility lines.

Once inside, radon can accumulate—especially in basements, lower levels, and areas close to the soil. A home’s age or construction quality cannot predict its radon concentration; a house with high radon levels can sit directly next door to one with safe levels. This is why every home must be evaluated individually.

Long-term exposure to elevated radon increases the risk of lung cancer. Professional testing provides the clear data needed to protect your household’s health.

When Should You Test for Radon?

Consider scheduling a radon test when:

• Buying an existing or newly constructed home
• Selling a home and preparing for due diligence
• Moving into a previously unused basement or lower level
• Completing major renovations or foundation work
• Installing or modifying HVAC systems
• Verifying an existing radon-reduction system
• Re-testing after several years or after a previous borderline result
• Seeking peace of mind about your current living space

Because soil conditions, weather, and building ventilation change over time, past test results may not reflect your home’s current environment.
