What 11 pCi/L Means for Piute County Homes
Very High Risk
Significantly above the EPA action level. Mitigation is strongly recommended for any home in this area. Long-term exposure at these levels can more than double lung cancer risk for non-smokers.
Piute County's average of 11 pCi/L is 4.1× the WHO mitigation threshold of 2.7 pCi/L and 2.8× the EPA action level of 4.0 pCi/L. Utah's statewide average is 4.4 pCi/L, and the national average is 1.3 pCi/L.
County averages represent the arithmetic mean of all pre-mitigation tests in the area — they don't mean every home will measure exactly 11 pCi/L. Radon levels vary significantly based on foundation type, soil composition, construction materials, and ventilation. Two adjacent homes can have radon levels that differ by a factor of 5 or more. The only way to know your home's level is to test.
There is no safe level of radon exposure. Long-term exposure to radon is the second-leading cause of lung cancer in the US, responsible for approximately 21,000 deaths annually. The good news: mitigation systems are effective, reliable, and typically reduce radon levels by 80–99%.
Why Does Piute County Have Elevated Radon Levels?
Piute County's average of 11 pCi/L reflects the geological composition of this area of Utah. The Wasatch Front's fault systems, basin geology, and uranium-bearing rock formations contribute to radon levels across the state. Soil type, foundation construction, and home ventilation all affect how much radon enters a specific home — which is why testing your individual home matters regardless of county or city averages.
Regardless of county-level geology, the only authoritative measurement for any home is a test conducted inside that specific building. Foundation type, crawl space vs. slab construction, and ventilation all dramatically affect indoor levels — which is why testing every home individually is the only reliable approach.
