What 32.7 pCi/L Means for Beaver County Homes

Extreme Risk

Among the highest recorded radon levels in Utah. Homes in this area should test immediately — these levels represent a serious long-term health risk. Mitigation is strongly recommended.

Beaver County's average of 32.7 pCi/L is 12.1× the WHO mitigation threshold of 2.7 pCi/L and 8.2× 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 32.7 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 Beaver County Have Elevated Radon Levels?

Beaver County's extreme radon levels are driven by uranium-rich volcanic and plutonic rock associated with the Tushar Mountains and surrounding mineral belts. The county contains some of the highest naturally occurring uranium concentrations in Utah, and the soil gas in this region carries radon into homes at levels rarely seen anywhere else in the country.

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.
