Radon Gas

More than 21,000 people die each year from radon exposure all over the United States. According to the Ohio Association of Radon Professionals website in Ohio 1 in 2 households have enough Radon to pose a significant risk to the occupants. Only smoking causes more lung cancer deaths than radon gas. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

How Radon Enters Homes

Radon Testing
Radon enters houses through: 1. Cracks in solid floors, 2. Construction joints, 3. Cracks in walls, 4. Gaps in suspended floors, 5. Gaps around service pipes, 6. Cavities inside walls, and 7. The water supply
Any home may have a radon problem: new and old homes, well-sealed and drafty homes, and homes with or without basements. Typically, radon moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Homes trap radon inside, where it can build up. ​ Radon from soil gasses is the main cause of problems. Sometimes radon enters the home through well water, and building materials rarely cause radon problems by themselves.

​Radon Causes Cancer

Nearly 1 out of every 15 homes in the U.S. is estimated to have elevated radon levels and the only way to know is to test. Homes next door to each other can have dramatically different radon levels, but it’s interesting that all counties in central Ohio have a predicted average indoor radon screening level greater than 4 pCi/L (picocuries per liter). The U.S. Environmental Protection Agency (EPA) recommends that Americans consider fixing their homes when the radon level is between 2 and 4 pCi/L.
Indoor radon is the second-leading cause of lung cancer in the United States and breathing it over prolonged periods can present a significant health risk to families all over the country

Radon Testing

The EPA urges that all homes be tested for radon. All homes—new and old, no matter where they are located—may have high levels of radon gas. You can’t see, smell, or taste radon. There are many ways to test for radon and many factors that can result in misleading measurements (for example, an open basement window may lower—or raise—radon levels). To get accurate testing results, it pays to get a highly qualified professional to do the job.

Howard Dunbar of APEX is licensed by the State of Ohio to test for radon in your home. 

To ensure accurate results, APEX uses a state-of-the-art continuous monitor that samples radon each hour for 48 hours. The tamper-resistant monitor senses and reports motion to secure dependable readings.

​Reducing Radon Levels

The EPA recommends that you reduce indoor radon levels that are 4 pCi/L or higher. It is better to correct a radon problem before placing homes on the market because you then have more time to fix the problem. If elevated levels are found during the real estate transaction, the buyer and seller should discuss the timing and costs of radon reduction (called “radon mitigation”). ​ The cost of making repairs to reduce radon levels depends on when the home was built and other factors. Most homes can be fixed for about the same cost as other common home repairs, like painting or having a new hot water heater installed. The average cost for a contractor to lower radon levels in homes can range from $800 to $2,500.

The U.S. Environmental Protection Agency (EPA) recommends:

  • Test your home for radon — it’s easy and inexpensive.
  • Fix your home if your radon level is 4 picocuries per liter (pCi/L) or higher.
  • Radon levels less than 4 pCi/L still pose a risk, and in many cases may be reduced.
