Radon in Colorado: What You Need To Know
Colorado’s unique geology, with its uranium-rich soils and rock formations, contributes to higher radon levels than many other states. Many homes exceed the Environmental Protection Agency’s (EPA) recommended action level of 4.0 picocuries per liter (pCi/L). While the EPA uses this level as an action point, it’s essential to understand that it does not represent a “safe” level. Exposure to 4.0 pCi/L carries a significant health risk over time, comparable to smoking approximately 8 cigarettes daily. At American Radon Mitigation, we believe there is no safe level of radon, so our goal is to get radon levels as low as possible in every home to minimize the risk of lung cancer. Let’s explore some key Colorado cities and regions and what residents should be aware of.
What is Radon?
Radon is a naturally occurring radioactive gas produced by the decay of uranium in rock, soil, and water. It seeps into homes and buildings through cracks in foundations, walls, and floors. Because it’s colorless, odorless, and tasteless, the only way to detect it is through testing.
The Dangers of Radon Exposure
Prolonged exposure to radon significantly increases the risk of lung cancer. In fact, the EPA considers radon the second leading cause of lung cancer in the United States, after smoking. It’s estimated that radon is responsible for thousands of lung cancer deaths each year.
Radon Levels in Colorado
- It’s crucial to note that the EPA designates most of Colorado as Zone 1, meaning a high potential for radon levels exceeding 4.0 pCi/L. This applies broadly across the state.
- However, there are areas with higher concentrations within the state.
City and Regional Spotlights
Denver Metro Area
- Denver and the surrounding metro area, including cities like Cherry Creek, Lakewood, Littleton, Highlands Ranch, Arvada, and Castle Rock, fall within a high-risk zone. The urban density means that a large population is potentially exposed.
- The City and County of Denver provide resources and strongly encourage testing, given the prevalence of radon in the region.
Foothills
- Radon poses a significant concern in Genesee, Evergreen, Golden, Morrison, and throughout Jefferson County and the foothills, where high radon concentrations are frequently detected.
- The prevalence of uranium-bearing granite and other rock formations in the foothills naturally generates radon gas. Fractures and faults in these rocks allow the gas to migrate to the surface, resulting in higher concentrations in the soil, water, and, subsequently, in homes.
Boulder
- According to Boulder County Public Health, a significant percentage of homes in Front Range cities like Boulder, Fort Collins, and Louisville have elevated radon levels.
- The proximity to the mountains and the specific soil types in this region play a role.
- Larimer County, where Fort Collins resides, is also a Zone 1 county, meaning it has the highest potential for radon.
Colorado Springs and the Pikes Peak Region
- This region, including Colorado Springs and surrounding areas in El Paso County, is known for particularly high radon levels. The geological makeup of the Pikes Peak granite contributes to this.
- Residents in this area should be especially vigilant about testing and mitigation.
Mountain Towns
- Areas like Vail, Breckenridge, Aspen, Steamboat Springs, and other mountain communities can also have high radon levels due to the prevalence of uranium-bearing rock.
- Due to the nature of mountain construction and how homes interact with the bedrock, extra care should be taken.
Key Recommendations
Test, Test, Test
Regardless of your location in Colorado, testing is the only way to know your home’s radon level. The EPA also recommends retesting your home every two years to ensure that radon levels remain low. Radon levels can fluctuate due to various factors, including changes in the ground, weather, and home conditions. Purchase an EPA-Approved Test Kit on our website.
Mitigation is Key
If your levels are high, don’t delay mitigation. Radon mitigation systems are effective and can significantly reduce your risk. Contact us for an estimate.
