WHAT IS RADON GAS?
The Invisible Health Risk in Northern Utah Homes, What Every Homeowner Needs to Know
Radon Gas 101
Radon is a colorless, odorless, tasteless radioactive gas formed by the natural decay of uranium in soil and rock. Outdoors, radon disperses harmlessly. The danger occurs when it accumulates inside enclosed spaces, like your home.
As radon decays, it releases radioactive particles that, when inhaled, damage lung tissue and cause lung cancer. Radon is the #1 cause of lung cancer in non-smokers, responsible for over 21,000 U.S. deaths annually.
Radon is measured in picocuries (PEE-koh-kyoo-reez) per liter (pCi/L). The EPA recommends action at 4 pCi/L or above. The average untreated indoor radon level in Utah is 4.5 to 5.3 pCi/L. The national average indoor level is 1.3 pCi/L.

How Does Radon Enter Your Home
Radon gas enters your home or business by seeping up from the soil sourounding the structure. Air pressure inside the building is usually lower than the pressure in the soil so it acts as a vacuum, sucking the soil gas which includes radon, in through the cracks and gaps in the foundation.
Foundation Cracks
Cracks in concrete slabs and foundation walls are the most common entry point.
Pipe Penetrations
Gaps around plumbing, electrical, and HVAC penetrations through the foundation.
Crawlspace Floors
Unencapsulated crawlspaces allow radon to rise directly from soil.
Well Water
Private wells may have radon in water that releases into air when used.
EPA Radon Risk Levels
Above 8 pCi/L — Very high risk. Mitigate immediately.
4–8 pCi/L — High Risk. Mitigation strongly recommended.
2–3 pCi/L — Moderate. Consider mitigation
Below 2 pCi/L — Lower Risk. Re-test every 2 years.
Why Utah Has High Radon Levels
☢️
Utah’s geology includes significant uranium deposits, the primary radon source.
⛰️
Lower atmospheric pressure at Utah’s elevation draws more radon from the soil.
🏠
Energy-efficient, tightly sealed Utah homes trap more radon indoors.
📈
Utah consistently ranks among top states for elevated indoor radon. Multiple Zone 1 counties.
