Radon is a silent threat that many homeowners and buyers overlook. It’s a radioactive gas that you cannot see, smell, or taste, but it can cause serious health problems. Testing your home for radon is the only way to know if you and your family are at risk. I want to share why radon testing matters, how it works, and what you can do if your home has high radon levels.

What Is Radon and Why Should You Care?
Radon is a naturally occurring gas that comes from the breakdown of soil, rock, and water. It can enter your home through cracks in the foundation, gaps around pipes, or other openings. Once inside, radon can build up to dangerous levels, especially in lower areas like basements.
Radon is the second leading cause of lung cancer in the United States, according to the Environmental Protection Agency (EPA). The risk increases if you smoke or have been exposed to radon for a long time. Many homes in Ohio, including the Southwest and Central regions where we service, have elevated radon levels because of the local geology.
You might wonder, “How do I know if my home has radon?” The answer is simple: testing. Without testing, you have no way to tell if radon is a problem in your home.
How Radon Testing Works
Radon testing is straightforward and affordable. You can buy radon test kits online or from local stores. We also offer professional radon testing services. For example, One Source Inspection provides radon testing as part of their home inspection services in Southwest and Central Ohio. We use reliable equipment and follow EPA guidelines to ensure accurate results.
What to Do If Your Radon Levels Are High
The EPA recommends taking action if your home’s radon level is 4 picocuries per liter (pCi/L) or higher. If your test shows high radon, don’t panic. There are effective ways to reduce radon levels.
One common method is called radon mitigation. This involves installing a system that vents radon gas from beneath your home to the outside. A professional radon mitigation service can assess your home and install the right system. This usually includes a vent pipe and a fan to pull radon out safely.
If you’re buying or selling a home, radon testing and mitigation can be part of the inspection process. One Source Inspection offers radon testing along with other important services like water quality tests and wood-destroying insect inspections. This helps you get a full picture of the home’s condition and safety.

Other Home Safety Tests to Consider
Radon testing is one part of a thorough home inspection. Other tests can help you understand your home’s safety and condition better.
Water quality testing checks for contaminants in your drinking water. This is important if you use a well or live in an area with known water issues.
Wood-destroying insect inspection looks for termites or other pests that can damage your home’s structure.
