Radon in Colorado: What Every Homeowner Should Know
Professional radon testing helps identify elevated indoor radon levels.
Professional testing is the only reliable way to determine your home’s radon levels.
Why Are Radon Levels High in Colorado?
Colorado consistently ranks among the states with the highest radon levels in the United States. This is primarily due to the natural geology of the region.
Radon gas forms from the breakdown of uranium found in soil, rock, and groundwater. Much of Colorado’s soil contains granite and uranium-rich formations that allow radon gas to move easily toward the surface.
Because radon cannot be seen or smelled, professional testing is the only reliable way to determine your home’s radon levels
Where Is Radon Most Common in Colorado?
Radon can be found throughout Colorado, but certain regions consistently report higher concentrations due to soil composition and geological conditions.
Homes along the Front Range — including Denver, Aurora, Lakewood, Thornton, and surrounding communities — frequently test above the EPA action level of 4.0 pCi/L.
Elevated radon levels are common in both older homes and new construction. Modern energy-efficient homes can sometimes trap radon more effectively, allowing concentrations to build indoors.
Because radon levels vary significantly from one property to another, testing remains the only reliable way to determine exposure risk.
How Does Radon Enter Homes?
Radon gas forms naturally in the soil beneath homes and moves upward through the ground. Differences in air pressure between the soil and the interior of a home can draw radon gas inside.
Common entry points include foundation cracks, construction joints, sump pits, crawlspaces, basement slabs, and small openings around pipes or utility lines.
Because radon is invisible and odorless, homeowners typically have no warning signs when elevated levels are present indoors.
Professional testing is the only reliable way to detect indoor radon levels.
Why Radon Testing Is Essential in Colorado
Radon cannot be seen, smelled, or tasted. The only reliable way to know your home’s radon level is through professional testing.
In Colorado, elevated radon levels have been found in homes of all ages — including new construction properties built with modern energy-efficient standards.
