You might have heard the term “radon” before, but many homeowners don’t fully understand what it is or the risks it poses. Radon is an invisible, odorless, and tasteless gas, which makes it impossible to detect without special equipment.

Because it can be present in any home, understanding this naturally occurring gas is the first step toward ensuring your living space is safe and healthy for you and your family. This guide will explain what radon is, where it comes from, and how it enters your home.

Where Does Radon Come From?

When uranium in soil, rock and water naturally breaks down over time, it naturally emits radon gas. Uranium is found in small amounts in most types of soil and rock, but in some areas, including parts of Utah and Nevada, it occurs at higher concentrations.

As uranium decays, it releases radon gas, which then moves up from the ground into the air. Outside, radon disperses quickly and is generally not a health concern. However, when it seeps into a home, it can accumulate to dangerous levels.

How Does Radon Enter Your Home?

Because radon is a gas, it can easily find its way into your home through any opening in contact with the ground. It most commonly enters houses via gaps in the foundation, openings around service pipes, construction joints, and even through well water.

The air pressure inside a home is usually lower than the soil pressure around the foundation. This pressure difference creates a vacuum effect, actively pulling radon gas from the ground into your house. This is why, even if you don’t have a basement, you need to test for radon in your home.

Radon Exposure and Health Risks

When radon gas accumulates indoors, people can inhale it. Once in the lungs, radon particles continue to decay, releasing small bursts of radiation. This radiation can damage the cells that line the lungs, which, over time, can cause lung cancer.

The U.S. Environmental Protection Agency (EPA) names radon as a leading cause of lung cancer, behind only smoking. The risk is particularly high for individuals who smoke, but non-smokers are also at risk from long-term exposure.

Testing and Mitigation

Now that we know what radon is and how it enters your home, you must know how to test for it. Since you can’t see or smell radon, you must test your home to determine if there are elevated levels of it. You can use a simple do-it-yourself test kit or hire a certified professional to conduct the testing.

If a test reveals high radon levels, you’ll need to install a mitigation system. These systems reduce radon concentrations in your home. The most common type is a pipe system that extracts radon from beneath the house and vents it safely to the outside.

Protect Your Home and Health

Radon is a serious health risk, but it is one that you can manage. By understanding what radon is and testing your home, you can take the necessary steps to protect your health and ensure your peace of mind. A simple test can provide you with the information you need to keep your home safe for years to come.
