5 Shocking Myths About Radon That Could Cost You Your Life

March 4, 2025

Think you know radon? Uncover the dangerous myths that might be putting your Denver family at risk of lung cancer, and learn the truth to stay safe from this silent killer.


Picture this: you’re breathing in a silent, odorless killer every day in your Denver home, unaware that a deadly gas called radon is raising your risk of lung cancer with every inhale—yet common myths about radon could be keeping you in the dark, potentially costing you or your family’s life. Radon, the second leading cause of lung cancer in the U.S., seeps into homes through foundations, crawlspaces, or slabs, building up to hazardous levels without any warning signs, but misconceptions about this invisible threat are rampant. Don’t let these dangerous myths leave you vulnerable to a catastrophic health crisis—here are five shocking myths you need to debunk right now to safeguard your home and loved ones from radon’s devastating impact.

Myth 1: Only Old Homes Have Radon Problems


Many Denver homeowners believe radon only affects older homes with visible cracks or outdated construction, but this couldn’t be further from the truth. This deadly gas can infiltrate new, modern homes just as easily, especially in our area’s uranium-rich soil, where radon is trapped and released into homes regardless of age or build quality. Imagine moving into a brand-new house, thinking you’re safe, only to discover radon has been silently poisoning your air from day one—don’t assume your home is immune.

Myth 2: You Can Smell or See Radon


It’s a terrifying misconception that you can detect radon with your senses, but this gas is completely undetectable without testing—it’s odorless, colorless, and tasteless, silently raising your lung cancer risk while you remain blissfully unaware. You could be living with dangerously high levels for years, breathing in this radioactive poison every day, without ever suspecting the danger lurking in your living room or bedroom. The only way to know for sure is through testing—and delaying could put your family’s health on the line.

Myth 3: Radon Isn’t a Big Deal in Denver


Some believe Denver’s climate or location makes radon less of a concern, but the reality is grim: our area’s geology, with its rocky soil and uranium deposits, actually heightens the risk, making thousands of local homes prime targets for this silent killer. Studies show that nearly 1 in 15 homes nationwide has elevated radon levels, but in high-risk zones like Denver, that number could be even higher, silently endangering families without them knowing. Don’t underestimate this threat—it’s a ticking time bomb in your home.

Myth 4: Radon Mitigation Is Too Expensive or Complicated


Many fear that fixing a radon problem is unaffordable or overly complex, but the truth is, testing and mitigation can be surprisingly simple and cost-effective, often completed in just 3-4 hours with solutions you can trust. The real cost? Ignoring radon could lead to devastating health consequences, including lung cancer, that far outweigh any investment in safety. Don’t let fear of cost or complexity keep you from protecting your family from this lethal gas.

Myth 5: Only Smokers Need to Worry About Radon


A dangerous myth suggests radon only poses a risk to smokers, but this couldn’t be more misleading—non-smokers are equally vulnerable to lung cancer from long-term radon exposure, making it a universal threat you can’t ignore. Imagine a non-smoking parent or child developing lung cancer because of undetected radon in their home—don’t assume you’re safe just because you don’t smoke. This silent killer affects everyone, and it’s your responsibility to act.

These myths aren’t just misleading—they could be deadly, leaving your family exposed to radon’s catastrophic potential without you even realizing it. This invisible gas doesn’t give warnings, and its damage builds silently over time, potentially leading to a lung cancer diagnosis that could have been prevented. But there’s hope: testing is the first critical step to uncovering this danger, and it’s easier and more affordable than you think.
