Smokers and Radon: What You Need to Know About Exposure

September 17, 2026      

Radon is an invisible, radioactive gas that can enter homes through foundation cracks, gaps, and other openings in the structure. Since it has no color or odor, you cannot tell when radon is present without testing. Although elevated radon levels can affect anyone, smokers and former smokers should be especially aware of the added risk associated with radon exposure.

Radon Can Increase Lung Cancer Risk

Long-term exposure to elevated levels of radon can increase the risk of lung cancer. As radon breaks down, it releases radioactive particles that can be inhaled and become trapped in the lungs. Continued exposure may damage lung tissue over time.

For people who smoke, this is particularly concerning because smoking is already a significant risk factor for lung cancer. Exposure to both tobacco smoke and radon can further increase overall lung cancer risk.

Why Smokers Should Test Their Homes

You may assume that your home is safe because there are no unusual odors or visible signs of a problem. However, radon cannot be detected by sight, smell, or taste. Testing is the only reliable way to determine whether elevated radon levels are present.

Smokers, former smokers, and households with a history of smoking should consider making radon testing part of their home's overall safety routine. Testing is also important for anyone who regularly spends time in basements or other lower areas of the home.

What If Radon Levels Are High?

If testing reveals elevated radon levels, the next step is to consider professional radon mitigation. A properly designed mitigation system can help reduce radon entering the home and lower indoor concentrations.

A professional radon specialist can assess your home's foundation and construction and determine which mitigation method is appropriate for the property. After installation, additional testing can help confirm that radon levels have been reduced.

Take Radon Exposure Seriously

Being aware of your home's radon level is an important step toward reducing unnecessary exposure. This is particularly relevant for current and former smokers who already face an increased risk of lung cancer.

The Radon Guys can help homeowners address concerns about radon through professional mitigation services. If you have never tested your home or are concerned about an existing radon problem, taking action can help you make informed decisions about your indoor environment.
