Understanding Radon Exposure Risks and Prevention
When most people think of environmental poisoning, they think of lead or carbon monoxide. But another environmental hazard can be just as deadly: radon. Radon is a naturally occurring radioactive gas that can seep into your home through cracks in the foundation, and it’s responsible for approximately 21,000 lung cancer deaths each year in the United States.
While radon is often described as “poisoning,” it doesn’t cause poisoning in the traditional sense. Instead, long-term exposure to elevated radon levels damages lung tissue at the cellular level. Over time, this damage can lead to lung cancer.
This blog post answers the common question: how long does it take for radon exposure to show symptoms? And what can you do to protect yourself and your family?
Understanding Radon Exposure
Radon forms from the natural breakdown of uranium in soil, rock, and water. It is invisible, odorless, and tasteless. Because of this, you cannot see, smell, or feel when radon is present in your home.
Radon can enter any building — homes, schools, offices — through cracks in foundations, gaps around pipes, sump pits, construction joints, and other openings. Once inside, it can accumulate to dangerous levels, especially in lower areas like basements and crawl spaces.
The Only Way To Know Your Radon Level Is To Test Your Home
The U.S. Environmental Protection Agency (EPA) recommends taking action if radon levels reach 4.0 picocuries per liter (pCi/L) or higher. Even levels between 2.0 and 4.0 pCi/L may pose a risk over long periods, and many homeowners choose mitigation at those levels as well.
How Long Can You Be Exposed Before It Becomes a Problem?
Radon exposure does not cause immediate symptoms. You won’t feel sick, dizzy, or short of breath from short-term exposure. Instead, radon releases radioactive particles that, when inhaled, can damage the cells lining your lungs.
This damage builds slowly over time. In many cases, lung cancer related to radon exposure develops after 10 to 20 years of prolonged exposure to elevated levels. The risk is significantly higher for smokers, as tobacco use combined with radon exposure greatly increases the likelihood of developing lung cancer.
Symptoms of lung cancer may include:
- Persistent chest pain
- Chronic cough
- Shortness of breath
- Hoarseness
- Difficulty swallowing
By the time symptoms appear, lung cancer may already be in advanced stages. That’s why prevention and early mitigation are critical.
Radon Exposure Diagnosis
There is currently no medical test that can determine whether radon has damaged your lungs. Doctors cannot measure radon exposure directly in the body.
If your home tests at or above 4.0 pCi/L, or if you believe you have been exposed to high radon levels for years, speak with your healthcare provider about your risk factors — especially if you smoke or previously smoked.
Protect Your St. Louis Home From Radon Exposure With Radon Control Services
If your test results show elevated radon levels, mitigation can significantly reduce your risk. The most common and effective solution is a system called sub-slab depressurization.
Sub-slab depressurization works by installing a vent pipe and fan system beneath your home’s foundation. The system creates negative pressure under the slab, pulling radon gas from the soil before it can enter your home. The radon is then safely vented above the roofline, where it disperses into the outdoor air.
This continuous system prevents radon from accumulating indoors and can reduce levels by up to 99% in many homes.
Radon exposure is a serious health risk, but it is manageable with proper testing and professional mitigation. Radon Control Services offers expert radon mitigation solutions tailored to your home’s construction and needs. Our trained professionals install reliable systems designed to protect your family’s long-term health.
If your home hasn’t been tested — or if your results are at or above 4.0 pCi/L — now is the time to act. Contact Radon Control Services today to schedule your installation appointment and take control of your indoor air quality.
