Health Risks of Radon Exposure: Facts Every Family Should Know

Radon is an invisible, odorless radioactive gas that affects millions of homes across the United States — including many in the Cincinnati area. Because you can’t see, smell, or taste radon, many families aren’t aware of the danger it can pose. However, understanding the health risks of radon exposure is crucial to protecting your loved ones and ensuring a safer home.

In this article, we’ll explain what radon is, how it affects your health, and why Cincinnati homeowners should take radon seriously.

What Is Radon?

Radon is a naturally occurring gas created by the breakdown of uranium in soil, rock, and water. As the gas forms, it moves through the ground and can enter buildings through cracks in the foundation, gaps around pipes, crawlspaces, sump pits, and other openings.
​
Once inside your home, radon can accumulate to dangerous levels — especially in basements and lower floors where air circulation is limited.

How Radon Enters Your Home

Radon moves upward through soil and into the air. Since buildings don’t have solid barriers between the ground and interior air, radon can seep indoors through:

• Cracks in concrete slabs
• Gaps in foundation walls
• Utility and pipe penetrations
• Crawlspaces
• Floor drains and sump pumps
  
  

Even small openings are enough for radon to enter and build up over time.

Why Radon Is a Serious Health Risk

Unlike many environmental hazards, radon doesn’t make you sick immediately. The danger lies in long-term exposure — especially at elevated levels.

Radon Causes Lung Cancer

Radon is the second leading cause of lung cancer in the U.S., only behind smoking. According to national health data:

• Radon exposure is responsible for thousands of lung cancer deaths each year.
• Lung cancer from radon can occur in both smokers and non-smokers.
• The risk increases with the level of radon and the duration of exposure.
  
  

When radon gas is inhaled, radioactive particles can become lodged in lung tissue. Over months and years, radiation from decaying radon particles damages cells and increases the likelihood of cancer development.

Other Potential Health Concerns

While lung cancer is the primary risk associated with radon, research suggests that long-term exposure may be linked to:

• Respiratory irritation
• Chronic coughing or breathing difficulty
• Aggravation of asthma symptoms

It’s important to note that lung cancer remains the most well-documented and serious outcome associated with radon exposure.

How Much Radon Is Dangerous?

Radon levels are measured in picocuries per liter (pCi/L) of air. The U.S. Environmental Protection Agency (EPA) recommends:

• Action at 4.0 pCi/L or higher.
• Even levels between 2.0 and 4.0 pCi/L pose a risk and should be considered for mitigation.
  ​

Because radon levels vary from home to home — even within the same neighborhood — testing is the only reliable way to know your home's radon level.

Testing Is the First Step to Protection

Radon gas cannot be detected without testing. Fortunately:

• Radon testing is affordable and easy to do.
• Professional radon testing provides accurate results.
• DIY test kits can be a good first step, but professional evaluation is often recommended for final decisions.
  

Reducing Radon Levels Can Protect Your Family

If high radon levels are found in your home, professional radon mitigation systems can:
✔ Lower indoor radon concentrations
✔ Reduce health risks associated with exposure
✔ Provide peace of mind in your living environment
Common mitigation methods include sub-slab depressurization, improved ventilation, and sealing entry points. A certified mitigation specialist will choose the best system based on your home’s design and radon level.

Final Thought

If you live in the Cincinnati area, don’t assume your home is safe without testing. Whether you’ve lived in your house for years or just moved in, knowing your radon level is one of the most important steps you can take to protect your family’s health.

Professional radon testing and mitigation can dramatically reduce exposure and provide lasting peace of mind. Taking action today helps ensure a healthier home for years to come.
