Radon Is Invisible - But the Risk Is Real

Find out how radon forms, why it’s dangerous, and how professional testing can help protect your home or commercial property.

What Is Radon Gas?

Radon is a naturally occurring radioactive gas formed by the breakdown of uranium in soil, rock, and groundwater. It is invisible, odorless, and tasteless, meaning it cannot be detected without specialized testing.

Radon exists both outdoors and indoors. While outdoor radon levels are typically low and diluted by open air, indoor radon can accumulate to higher concentrations, especially in enclosed spaces such as basements and crawlspaces.

What Causes Radon Gas?

Radon is produced through the natural radioactive decay of uranium found in the earth. As uranium decays, it releases radon gas, which can move through soil and into buildings. 

Radon levels vary depending on:

Local geology and soil composition

Foundation construction

Building ventilation

Structural openings and cracks

Radon can enter a home or building through:

Cracks in foundations

Gaps around pipes and utility penetrations

Sump pits

Crawlspaces

Well water (in some cases)

Importantly, any home can have elevated radon levels, regardless of:

Age (new or old)

Construction type

Whether it has a basement

How well it is sealed

The only way to know radon levels is through professional testing.

Is Radon Gas Dangerous?

Yes. Radon is classified as a carcinogen by the U.S. Environmental Protection Agency (EPA) and the World Health Organization (WHO).

Long-term exposure to elevated radon levels increases the risk of lung cancer. In fact, radon is the second leading cause of lung cancer in the United States after smoking.

According to the EPA, approximately 21,000 lung cancer deaths per year are linked to radon exposure.

Risk increases with:

Higher radon concentrations

Longer exposure duration

Smoking history

Because radon has no smell or visible warning signs, many people are unaware they are being exposed.

Radon Exposure Symptoms

Radon exposure does not cause immediate symptoms such as irritation or odor. The primary health concern is long-term lung damage that may eventually contribute to lung cancer. Symptoms associated with advanced lung conditions may include:

Persistent cough

Shortness of breath

Chest pain

Hoarseness

Wheezing

Unexplained weight loss

Coughing up blood

It is important to note that there is no specific “radon poisoning” test. The safest approach is prevention through testing and mitigation if necessary.

How to Protect Your Home from Radon

The only reliable way to determine radon levels in your home or commercial building is through radon testing.

The EPA recommends action if indoor radon levels exceed 4.0 picocuries per liter (pCi/L), though mitigation may be considered at lower levels.

Professional radon testing:

Measures indoor radon concentration

Provides documented results

Supports real estate transactions

Identifies whether mitigation is recommended

If elevated levels are detected, mitigation systems can effectively reduce radon concentrations.
