Radon is a naturally occurring, colorless, odorless, and tasteless radioactive gas. It is formed through the breakdown of uranium in soil, rock, and water. Though it’s present in trace amounts outdoors and generally harmless, radon becomes a significant health concern when it accumulates inside homes and buildings.
Radon seeps into buildings through cracks in foundations, gaps around pipes, construction joints, and even through porous materials like concrete. Homes with poor ventilation are particularly susceptible, as radon can become trapped and reach harmful levels. Since the gas is derived from natural sources, it can affect any home, regardless of age, location, or structure type.
Radon is the second leading cause of lung cancer after smoking and the number one cause of cancer among non-smokers, according to the Environmental Protection Agency (EPA). When inhaled, radon particles can lodge in the lungs and emit radiation, which damages lung tissue over time. This exposure increases the risk of developing lung cancer.
The only way to know if your home has a radon problem is through testing. Radon test kits are affordable and widely available online (click here for tests from the American Lung Association that are free to $30 each) or at hardware stores. These kits allow homeowners to collect air samples and send them to a lab for analysis. You can also hire a certified radon professional to conduct a more comprehensive assessment.
If testing reveals high radon levels (4 pCi/L or higher, as per EPA guidelines), take immediate action. Common mitigation methods include:
- Sealing Entry Points – Filling cracks in the foundation and sealing gaps around pipes can help reduce radon entry.
- Improving Ventilation – Increasing airflow in your home can disperse radon and lower its concentration.
- Installing a Radon Mitigation System – These systems use a vent pipe and fan to pull radon from beneath the house and release it safely outside.
Prevention starts with awareness. By testing for radon and taking appropriate measures, you can protect your home and family from this invisible hazard. Take action today and ensure your indoor air remains safe.
