Across Colorado, from Denver to Fort Collins and Castle Rock to Winter Park, roughly one in two homes have elevated radon levels. Despite how widespread radon is in our state, misinformation continues to circulate. These myths about radon can lead homeowners to skip radon testing or put off installing a radon mitigation system, creating unnecessary risk for their families.
Does Radon Only Affect Older Homes?
Many homeowners in Denver and Fort Collins assume that radon is only a concern in older properties. The truth is that radon is a naturally occurring gas that seeps into any home through cracks and gaps in the foundation, regardless of when the structure was built.
Brand-new construction in Castle Rock or Winter Park can have just as high of radon levels as a home built several decades ago. Colorado’s unique geology plays a significant role in radon exposure, and the soil beneath your home doesn’t distinguish between older and newer foundations.
Modern building codes have evolved to include radon-resistant features in new construction, but those features alone are not a guarantee of lower levels. They may reduce the likelihood of elevated concentrations, but radon testing is still the only reliable way to know your actual levels. If your results come back above 4.0 pCi/L, a radon mitigation system is the recommended next step to bring your home’s radon levels down.
Can You Smell or Detect Radon Without a Test?
Radon is a colorless, odorless, and tasteless gas. There is no physical way to detect it without proper testing equipment. Homeowners across Colorado, from Winter Park to Castle Rock, sometimes assume they would notice something if radon were present in their home. Unfortunately, that is not the case.
Because radon comes from the natural breakdown of uranium in the soil, it enters your home silently through the foundation. You could be living with elevated levels for years without ever knowing. That is exactly why radon testing is so important, especially in a high-risk state like Colorado.
Professional radon testing gives you a clear, accurate reading of the levels in your home. If concentrations exceed the EPA’s recommended action level of 4.0 pCi/L, a radon mitigation system can be installed to reduce those levels. Without a test, there is simply no way to tell whether your family is being exposed. Don’t rely on guesswork when reliable testing is readily available.
Is Radon Only a Problem in Basements?
It is a common belief that radon is limited to basements, but that is not the full picture. While basements often show the highest concentrations because of their direct contact with the soil, radon can accumulate on any level of a home. Homeowners in Denver, Fort Collins, and throughout Colorado should be aware of these key facts:
- Radon enters through the foundation, not just basement walls. Any level of a home that sits on or near a slab or crawlspace can be affected, including main floors and split-level layouts common across Castle Rock and Winter Park.
- Upper floors are not automatically in the clear. Radon can travel through HVAC systems, gaps in flooring, and natural airflow patterns to reach the second or third story of a home.
- Homes without basements still need radon testing. Slab-on-grade homes are just as susceptible since radon seeps directly through the concrete and into living spaces.
- Every home is different. Two neighboring homes in Fort Collins can have completely different radon levels based on foundation type, soil composition, and ventilation, which is why individual radon testing is always recommended.
Is Radon Only a Problem in Winter?
Some homeowners believe that radon is only a seasonal concern, peaking in winter and dropping off during warmer months. While it is true that radon levels can fluctuate throughout the year, radon is present in the soil 365 days a year. Colorado homes in Denver, Castle Rock, Winter Park, and Fort Collins are exposed to radon regardless of the season. Here is why this myth can be misleading:
- Radon is generated continuously. The uranium in Colorado’s soil does not stop decaying when temperatures rise. Radon is produced year-round, which means it is always capable of entering your home.
- Summer conditions can still drive radon indoors. Air conditioning, closed windows, and changes in air pressure can create conditions that actually pull radon into the home during warmer months.
- Seasonal fluctuations do not mean the risk disappears. A home in Fort Collins that tests high in January may still have elevated levels in July. The levels may shift, but they rarely drop to zero on their own.
- Year-round protection matters. A radon mitigation system operates continuously, keeping levels reduced no matter the time of year or weather conditions outside.
Does Radon Only Cause Lung Cancer in Smokers?
Radon is the number one cause of lung cancer among nonsmokers in the United States. While smoking combined with radon exposure does significantly increase the risk, nonsmokers are far from unaffected. Families across Denver, Castle Rock, and Fort Collins should understand that radon does not discriminate based on lifestyle.
When radon gas is inhaled, radioactive particles can become trapped in the lungs. Over time, these particles damage lung tissue and can lead to cancer. This process happens regardless of whether the person has ever smoked. The EPA estimates that radon is responsible for approximately 21,000 lung cancer deaths each year, and a meaningful portion of those are among people who have never picked up a cigarette.
This is one of the strongest reasons to prioritize radon testing in your home. If elevated levels are found, a radon mitigation system is a proven and effective solution. Protecting your household from prolonged radon exposure is something every Colorado homeowner should take seriously, no matter their smoking history.
