Why Smokers Have Higher Radon Risk — What Omaha Families Should Know

3/20/2026

Radon is a serious health concern in many parts of the U.S., including the Omaha area. But did you know that smokers face an even greater health risk from radon exposure than non-smokers? While radon is dangerous for everyone, the combination of smoking and radon creates a multiplying effect on lung cancer risk.

In this article, we’ll explain why smokers have higher radon risk, how radon and smoking interact in the lungs, and what every Omaha family — especially households with smokers — should know to protect their health.

What Is Radon and Why Is It Dangerous?

Radon is a naturally occurring radioactive gas that forms when uranium in soil and rock breaks down. It can enter homes through cracks in foundations, gaps around pipes, and other openings in the building envelope. Since it’s colorless, odorless, and tasteless, the only way to know if it’s present is through testing.

Once inside your home, radon can accumulate to high levels — especially in lower areas like basements and crawlspaces. When radon gas is inhaled, radioactive particles can become lodged in lung tissue. Over time, radiation damages cells, increasing the risk of lung cancer.

Radon and Smoking: A Dangerous Combination

Both radon exposure and cigarette smoking independently increase lung cancer risk — but when combined, the risk grows much higher than the sum of the two.

Here’s how they interact:

1. Smoking Damages Lung Tissue First

Tobacco smoke contains thousands of chemicals, including numerous carcinogens. These substances:

Impair the lung’s natural defenses
Cause inflammation
Create damaged tissue that’s more vulnerable to radiation

When radon particles are inhaled into lungs already weakened by smoking, they have an easier path to cause DNA damage and lead to cancer.

2. Radon Particles Stick Longer in Smokers’ Lungs

Healthy lungs have mechanisms that help clear out foreign particles. Smoking interferes with those natural defenses, meaning radon decay products can:

Stay lodged in lung tissue longer
Continue releasing radiation directly where it causes the most harm

This increases the cumulative damage over time.

3. Multiplicative, Not Just Additive Risk

Studies have shown that the combined risk of radon and smoking is multiplicative — meaning:
➡ A smoker exposed to radon has a much higher chance of lung cancer than someone who only smokes or only lives with radon.

According to research, a smoker with high radon exposure may face a tenfold or greater increase in lung cancer risk compared to a non-smoker with similar radon exposure.

What This Means for Omaha Households

If you live in the Omaha area, understanding this relationship is crucial:
🔹 Radon exposure alone is dangerous.
🔹 Smoking alone increases lung cancer risk.
🔹 Smoking plus radon greatly increases that risk — especially over time.

For families with smokers, the stakes are even higher. This makes radon testing and mitigation especially important in homes where people smoke or lived there previously.

Taking Action: Testing and Mitigation

Because radon is invisible, the only way to know your levels is through testing:
📍 Step 1: Test Your Home

Use a professional radon test or an EPA-approved test kit
Test in lowest lived-in level (basement, first floor)
Consider year-round or seasonal testing for accuracy

📍 Step 2: Review Your Results

Levels above 4.0 pCi/L are considered actionable
Levels between 2.0–4.0 pCi/L are concerning and worth mitigation

📍 Step 3: Mitigate If Needed
A certified radon mitigation system can reduce radon levels dramatically, lowering the health risk for everyone in your home — especially smokers.

Final Thoughts

Radon is a health risk for all homeowners — but for smokers and former smokers, the danger is significantly greater. Because smoking damages lung tissue and reduces natural defenses, radon’s harmful effects are amplified.

If you live in Omaha and haven’t tested your home for radon — or if you have smokers in your household — now is the time to act. Testing and mitigation can offer real protection against long-term health risks like lung cancer.

Your home should be a safe place — not a source of hidden health hazards. Take the first step and test for radon today. CALL OMAHA RADON PROS.

What Are the Types of Homes with High Radon in Omaha?

5/18/2023

Radon is a colorless, odorless substance produced by the decomposition of uranium present in soil and rocks. It's the second most common cause of lung cancer and may significantly harm human health.

All homes contain radon, but some are more prone to higher levels than others. The homes in Omaha that contain the most radon will be examined in greater detail in this article.

Read on to learn more.

What Types of Homes in Omaha Have the Most Radon?

Below are a few types of homes in Omaha with high levels of radon:

Homes with Basements

Because they are frequently used as living spaces, basements can expose people to high levels of radon gas. This is due to the ease with which radon can enter basements through the soil, foundational fractures, and spaces around pipes and other openings.

Homes with unfinished basements run the danger of having high radon levels as a result of possible inadequate sealing.

Homes with Crawl Spaces

High levels of radon in Omaha might also come from vented or sealed crawl areas. Radon can infiltrate crawl spaces through the ground and foundation cracks, just like in basements.

Furthermore, radon levels in crawl spaces may rise due to frequent poor ventilation.

Homes Built on Bedrock or Granite

Homes constructed on granite or bedrock are more likely to have high radon levels due to the increased uranium content of these types of rocks. Radon gas is released into the soil and air around when uranium decays.

Homes constructed on these rock formations are consequently more vulnerable to high radon levels.

Radon concentrations can differ from place to place, with some having higher concentrations of radon than others. Omaha is situated in a region where radon levels are known to be greater, making homes more vulnerable to high radon levels.

Homes with Slab-On-Grade Foundations

Radon levels in homes with slab-on-grade foundations can be very high. This is because certain foundation types contain a lot of cracks and gaps around pipes that allow radon to enter the house.

Protect Your Family's Health: Take Radon Test for Any Home Type

No matter what kind of house you reside in, you should get radon evaluation done. A do-it-yourself testing kit or a professional testing service are also options for testing.

A radon mitigation system must be installed at lower levels if high radon levels are found. Radon gas is redirected from below the house and released outside via mitigation devices, which lowers the level of radon gas inside the house.

What Season Does Radon Risk Increase Most in Omaha?

5/18/2023

Radon is a silent killer responsible for lung cancer, and the levels can fluctuate throughout Omaha, Nebraska, depending on the season.

Recognizing when these levels peak can help homeowners take necessary precautions to protect their families.

So, what season is radon worst in Omaha?

Seasonal Variations in Radon Levels

Winter Radon Levels

The winter is often when radon levels reach their highest due to multiple factors. The thermal stack effect creates a suction effect that draws in air from below. Temperatures cause pressure within homes to increase, leading to additional seepage of radon into home.

Snow cover acts as an obstruction trapping more radon gas underneath, increasing concentration. Tightly sealed homes can also contribute to its accumulation.

Spring Radon Levels

As temperatures warm up and snow begins to melt in spring, soil moisture levels increase, which may contribute to an increase in radon levels; it is essential to remember, however, that radon levels may still be high during this season.

Summer Radon Levels

The summer season tends to experience lower radon levels than other times of the year due to people leaving windows and doors open and allowing air circulation freely.

However, this doesn't necessarily mean radon levels cannot rise, particularly in areas with poor ventilation.

Fall Radon Levels

As temperatures begin to cool off and windows close again, radon levels can start rising rapidly in homes that do not provide sufficient ventilation. As such, homes that do not adequately ventilate may see their levels spike rapidly again in autumn.

How to Lower Radon Levels in Residential Properties

Radon exposure can be hazardous to health. High levels can increase lung cancer risk. If your home contains high levels of radon, limit exposure and protect the well-being of yourself and your family by taking steps such as air filter replacements to lower exposure.

Testing for Radon: When do radon levels change over time? Step one in reducing radon levels in your home should be to have it professionally tested by an accredited testing service, using their specialized equipment to detect high radon concentration levels in your airspace. High-level detection offers accurate information regarding its presence.

Installing a Radon Mitigation System: When is radon highest in your area? If high radon levels have been identified in your home, installing a mitigation system to lower it may help. Installing a vent pipe and fan to pull radon from under your foundation and expel it outside is typically part of a mitigation system. Professional installation should ensure this occurs effectively and successfully.

Sealing Cracks and Openings: Sealing foundation cracks is another effective way to lower radon levels in your home, such as sealing floors, walls, and around pipes, windows, and doors. This helps prevent the gas from seeping in and entering.

Improving Ventilation: Opening windows and doors, using fans to move air, or installing a heat recovery ventilator (HRV) or energy recovery ventilator (ERV) system in your home are all excellent ways to improve ventilation and reduce radon levels. This will bring fresh air in and exhaust old air, thus helping lower radon levels in your home.

Regular Radon Testing: Regular radon testing is vital to keeping radon levels within your home at acceptable levels, mainly if there have been changes to its foundation or ventilation system. What time of year are radon levels highest? Testing should occur every two years to detect changes that might impact this.

Conclusion

Radon levels in Omaha vary with each season. Winter tends to bring higher radon concentrations due to the thermal stack effect, snow cover, and tightly sealed homes. Spring, fall, and summer may all see increased levels. But it's essential to note that radon can still be present throughout any season, so testing for it and taking measures to mitigate high levels is crucial for family health and well-being.

If your home contains high radon levels, the first step should be to install a radon mitigation system to lower levels and prevent long-term exposure. Hiring professional services will ensure this mitigation system is installed correctly and effectively. Read about Is a radon mitigation really necessary in Omaha?
