Radon is an invisible, odorless gas that can enter your home through tiny cracks in the foundation—and it’s more common in Utah than many people realize. Because of our geology, between one-third and one-half of Utah homes have elevated radon levels, and no county is considered risk-free. Long-term radon exposure is the leading cause of lung cancer in non-smokers, putting the health of your family, and pets, at risk. The good news: Testing is easy and affordable—and in many cases, free.
