Radon is present in the Carolinas. Could your home be affected? Why you should consider testing.

Updated: Jun 14

What is radon?

Radon is a naturally occurring radioactive gas found in parts of the Carolinas that comes from the natural breakdown of uranium in soil, rock, and water. It's odorless, colorless, and tasteless. As radon travels up through the ground to reach your home or workplace, it can enter your living space through cracks in the floor or walls. Radon is the second leading cause of lung cancer nationwide after smoking. If you're worried about radon exposure you should know these facts to protect your family. 1. Radon levels can vary widely

2. Radon testing is inexpensive and easy (Bannon Home Inspections provides radon testing)

3. There are ways to fix high radon levels

4. You can buy a radon mitigation system for your home

5. You should also test for radon in work spaces like schools and offices

How does radon get into your home or workplace?

Radon that enters your living space through cracks in the floor or walls is called "uncontrolled radon." It also seeps in from water, building materials, and soil. Radon can enter homes through poorly fitted windows, doors, or pipes.

Radon levels vary by region because of varying levels of uranium in soil, rock, and groundwater. Some regions have higher concentrations of the gas than others.

When you check the maps (courtesy: epa.gov/radon) for radon zone levels in the Carolinas, you see some varying data. For example, in North Carolina you’ll see: Iredell, Catawba, Lincoln and Gaston counties are orange zone 2. While counties like Mecklenburg, Union, Rowan and Cabarrus are yellow zone 3.

In South Carolina: York and Cherokee counties are in orange zone 2, while Chester, Lancaster, Fairfield, Kershaw and Chesterfield counties are in yellow zone 3.

It’s important to remember that regardless of where you live in North or South Carolina, Radon could be present.

To check for radon levels in your home or workplace, you might need to hire a qualified professional. At Bannon Home Inspections, we use continuous radon testers. They are placed in a location for 48 hours to check the levels of radon that may be present. We’re able to provide the results of a radon gas test shortly after the 48 hours testing period is completed.


Radon is a radioactive gas that can cause lung cancer and other serious health problems.
