In late 2014, the City of Holladay embarked on a Radon Education and Testing program with the intent of protecting our residents from the life-threatening effects of Radon.   Radon gas (the second leading cause of lung cancer in the US) is very prevalent in Holladay.   This testing has revealed that about one out of every three Holladay homes has a Radon problem, with one in ten experiencing Radon levels over twice EPA’s action level threshold.

Testing for your home:  In cooperation with the Utah Division of Radiation Control's Indoor Radon Program, the City has purchased Radon testing kits for the benefit of our residents. These kits are available at City Hall (4580 South 2300 East) for a nominal cost of $5 each for Holladay residents.  These short-term tests reflect 2-4 days of data collection providing a good snap-shot of probable problems. Testing is easy and should only take a few minutes of your time.

We continue to encourage Holladay homeowners to pick up a Radon test kit from the city.  If you have questions or wish to discuss your Radon test results, you should feel free to contact Eleanor Divver, the Utah Indoor Radon Coordinator, at 801-536-0091; or visit the State’s website at

 Radon Mitigation and Repairs:  The only way to know if your home is at risk is to test.  Although there is no known safe level of Radon, levels of 4 picocuries per liter (pCi/L) are considered the threshold requiring remedial action.  If your house is tested and the result shows your house has this high level of Radon gas, you may want to have a Radon reduction system professionally installed.  The right system depends on the design of your home and other factors. Usually, a simple ventilation and low-pressure fan system is installed to vent the Radon out of your home where it can safely dissipate in the atmosphere.

About Radon:  Radon gas is a colorless, odorless radioactive gas byproduct of the natural decay of uranium in soil, rock and water. These radioactive particles get trapped in your lungs and cause lung cancer. Smoking is the leading cause of lung cancer the US. If you smoke and your home has high Radon levels, your risk of lung cancer is especially high.  

Radon moves up through the ground into your home through cracks and other holes in the foundation. Your home traps Radon inside, where it can build up. Any home may have a Radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements. Testing shows that nearly 1 out of every 3 homes in Holladay experiences elevated Radon levels.
