Frequently Asked Questions

What Is Radon?

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and groundwater. Because it is invisible, odorless, and tasteless, radon can accumulate indoors without being detected. Long-term exposure to elevated radon levels is a known risk factor for lung cancer.

Where Does Radon Come From?

Radon forms naturally in the ground as certain elements break down over time. The gas can travel through soil and enter homes and buildings through cracks in foundations, utility penetrations, sump pits, crawl spaces, and other openings. Radon may also be present in some groundwater sources.

How Can I Tell If My Home Has Radon?

You cannot detect radon through sight, smell, or taste. Testing is the only reliable way to determine whether radon is present at elevated levels in your home or building.

Is Radon Dangerous?

Yes. Long-term exposure to elevated radon levels increases the risk of developing lung cancer. The risk generally increases as radon concentrations rise and exposure continues over time.

What Radon Level Is Considered High?

The U.S. Environmental Protection Agency (EPA) recommends taking action when indoor radon levels reach 4.0 pCi/L or higher. Many homeowners choose to reduce radon levels even below that threshold to further lower risk.

How Do I Test for Radon?

Radon can be measured using either short-term or long-term test kits. Most homeowners begin with a short-term test placed in the lowest regularly occupied area of the home. After the testing period is complete, the sample is sent to a laboratory for analysis.

Where Should a Radon Test Be Placed?

For the most accurate results, the test should be placed in the lowest level of the home that is regularly used, following the manufacturer’s instructions.

Can New Homes Have Radon?

Yes. Radon can affect homes of any age, size, design, or construction type. Even newly built homes may have elevated radon levels depending on local soil conditions.

Do Neighboring Homes Have Similar Radon Levels?

Not necessarily. Radon levels can vary significantly from one property to another, even between homes located next door to each other. This is why every property should be tested individually.

What Is Radon Mitigation?

Radon mitigation is the process of reducing indoor radon levels through specialized systems. The most common approach uses piping and a continuously operating fan to draw radon from beneath the building and safely vent it outdoors.

How Does a Radon Mitigation System Work?

A mitigation system creates negative pressure beneath the foundation, preventing radon from entering the living space. The collected gas is vented above the roofline where it safely disperses into the outdoor air.

Will a Mitigation System Eliminate All Radon?

While no system can guarantee a complete elimination of radon, professionally designed mitigation systems are highly effective at reducing radon concentrations and maintaining safer indoor air quality.

Should I Retest After Mitigation?

Yes. Follow-up testing is recommended after a mitigation system is installed to verify that radon levels have been reduced. Periodic testing can also help ensure continued system performance.

Can Radon Be Found in Commercial Buildings?

Yes. Radon can accumulate in offices, schools, warehouses, healthcare facilities, and other commercial properties. Testing and mitigation may be appropriate wherever people spend significant amounts of time indoors.

How Dangerous is Radon?

According to the U.S. Environmental Protection Agency (EPA), radon is the second leading cause of lung cancer in the United States and the leading cause among non-smokers. For smokers, radon exposure can significantly increase the risk of developing lung cancer.

Why Is Radon Dangerous?

Radon becomes a health concern when it accumulates indoors and is inhaled over long periods of time. As radon decays, it releases radioactive particles that can become lodged in the lungs. Continued exposure to these particles may damage lung tissue and increase the risk of lung cancer.

Because radon cannot be seen, smelled, or tasted, testing is the only way to determine whether elevated levels are present in your home or workplace. Radon concentrations are measured in picocuries per liter of air (pCi/L).

The EPA recommends taking action when radon levels reach or exceed 4.0 pCi/L. If elevated levels are detected, a professionally installed radon mitigation system can effectively reduce radon concentrations and improve indoor air quality.

At Rapid Radon, we design customized mitigation systems that safely redirect radon gas from beneath your home and vent it outside before it can enter living spaces.

How Common Is Radon?

Radon can be found in homes throughout Missouri and across the United States. In fact, the EPA estimates that nearly one out of every five homes tested has radon levels at or above the recommended action level.

One of the challenges of radon is that neighboring homes can have very different radon levels. A home with elevated radon may sit directly next to a home with low levels. Factors such as soil composition, foundation design, and construction methods can all influence radon concentrations.

Because radon levels vary from property to property, every home should be tested regardless of age, size, location, or construction type.

Radon and Your Family’s Health

Long-term exposure to elevated radon levels is a serious health concern. The EPA and the U.S. Surgeon General estimate that radon exposure contributes to more than 20,000 lung cancer deaths each year in the United States.

Children may be especially vulnerable because their lungs and bodies are still developing. Schools, daycare facilities, offices, and other occupied buildings can also be affected by elevated radon levels, making regular testing an important part of maintaining a healthy indoor environment.

The good news is that radon problems can be identified and corrected. Testing is simple, affordable, and the only way to know whether your home or building has elevated radon levels.

Protect Your Home With Rapid Radon

At Rapid Radon, our mission is to help homeowners, businesses, schools, and real estate professionals create safer indoor environments through reliable radon testing and mitigation services. Whether you’re testing your property for the first time or need a customized mitigation solution, our team is here to help you reduce your risk and gain peace of mind.

Don’t guess when it comes to radon—test your property and take the first step toward protecting your family, employees, and occupants.

The most common source of indoor radon is the ground beneath a home or building. As uranium naturally decays in the soil, radon gas is released and can move upward through cracks, gaps, sump pits, utility penetrations, crawl spaces, and other openings in the foundation.

Although radon also exists in certain mining environments and can be produced as a by-product of some industrial processes, residential exposure most often occurs when the gas becomes trapped indoors and accumulates to elevated levels.

Because radon cannot be seen, smelled, or tasted, professional testing is the only way to determine whether a home or business has elevated radon levels. At Rapid Radon, we educate homeowners and property owners about the facts surrounding radon, answer questions about potential risks, and provide dependable mitigation solutions when elevated levels are found.

Our goal is simple: deliver fast, reliable, and effective radon services that help protect your family, your home, and your peace of mind.

Step 1: Test Your Home for Radon

The first step in protecting your home is determining your radon level. Homeowners can use a do-it-yourself radon test kit available at most hardware stores, or schedule professional radon testing for accurate results.

If your test results show radon levels at or above 4.0 pCi/L, it’s important to take action. Contact Rapid Radon to discuss your options and schedule a mitigation consultation.

Step 2: Determine How Radon Is Entering Your Home

Radon can enter through several pathways, making it important to identify where the gas is infiltrating the structure. Understanding the source allows us to design the most effective mitigation system for your home.

Every home is different, which is why our radon mitigation systems are custom-designed based on factors such as your home’s radon levels, foundation type, layout, age, and square footage. Our goal is to provide an effective, long-term solution that reduces radon levels and helps create a healthier indoor environment.

Soil Gas & Pressure Differences (Stack Effect)

Radon is a naturally occurring gas found in soil throughout many regions of the United States. Differences in air pressure between your home’s interior and the soil beneath it can create a vacuum effect, often called the stack effect. This pressure imbalance can draw radon gas into the home through foundation cracks, expansion joints, sump pits, utility penetrations, and other openings.

How Mitigation Works

Professional radon mitigation systems are designed to reduce radon levels by controlling these pressure differences and redirecting soil gases away from the home. One of the most common and effective methods is Sub-Slab Depressurization (SSD), which creates negative pressure beneath the foundation and safely vents radon gas above the roofline before it can enter your living space.

At Rapid Radon, we evaluate each home individually to determine the most effective mitigation strategy and provide a reliable solution for long-term radon reduction.
