Radon Facts Every Utah Homeowner Should Know

What Is Radon?

Radon is one of the most serious indoor air quality hazards in Utah, yet it's completely invisible, odorless, and impossible to detect without proper testing. Understanding the facts about radon can help you protect your home, your family, and your long-term health. Whether you're buying a home, selling one, or simply want peace of mind, these essential radon facts will help you understand why testing matters.

Why Is Radon Dangerous?

Long-term exposure to elevated radon levels can significantly increase the risk of developing lung cancer. According to the U.S. Environmental Protection Agency (EPA):

• Radon is the leading cause of lung cancer among non-smokers.
• It is the second leading cause of lung cancer overall.
• Thousands of radon-related lung cancer deaths occur each year in the United States.
  

The good news is that radon problems can be identified through testing and effectively reduced with professional mitigation systems.

Why Utah Homes Are More Susceptible

Utah's geology contains naturally occurring uranium-rich soils that produce higher concentrations of radon gas.

Combined with seasonal weather changes and tightly sealed energy-efficient homes, radon can accumulate indoors and reach unhealthy levels. Even neighboring homes can have dramatically different radon readings, making individual testing essential for every property.

What Radon Level Is Considered Dangerous?

The EPA recommends taking action if your home tests at:

4.0 pCi/L or Higher - The World Health Organization recommends considering mitigation at: 2.7 pCi/L or Higher even lower levels carry some risk, which is why reducing radon exposure whenever possible is recommended.

How Does Radon Enter a Home?

Radon can enter through:

• Foundation cracks
• Basement floors
• Crawl spaces
• Construction joints
• Utility pipe openings
• Sump pump pits
• Concrete slab openings
  

Once inside, it can become trapped and build up over time.

Which Homes Should Be Tested?

The simple answer: Every home should be tested.

This includes:

• New homes
• Older homes
• Homes with basements
• Homes on concrete slabs
• Homes with crawl spaces
• Homes with existing mitigation systems
• Homes being bought or sold
  

Every property is different, and radon levels cannot be predicted based on nearby homes.

How Often Should You Test?

The EPA recommends testing:

• Every two years
• After major remodeling
• After installing a mitigation system
• Before purchasing a home
• Before selling a home
• After significant foundation repairs
  

Regular testing helps ensure your home remains protected over time.

Common Signs of Radon

Unfortunately, radon has no visible warning signs.

You cannot rely on:

• Smell
• Taste
• Color
• Physical symptoms
  

Testing is the only reliable way to know your home's radon level.

Can High Radon Levels Be Fixed?

Yes.

Professional radon mitigation systems are highly effective at reducing indoor radon concentrations. A certified mitigation system works by safely venting radon gas from beneath your home's foundation before it enters your living space. Most systems operate quietly, efficiently, and require very little maintenance.
