Champaign, IL – Public health officials in Champaign County are urging residents to test their homes for radon this month, warning that the invisible gas is the second leading cause of lung cancer in the United States.
According to the Champaign-Urbana Public Health District, radon cannot be seen or smelled and can build up indoors without homeowners realizing it. National data shows radon is found in 1 in 15 U.S. homes, including properties across Illinois.
January is recognized nationally as Radon Action Month, a time when health agencies encourage residents to take preventive steps. Officials say testing is especially important during winter, when homes are sealed tightly and radon levels can rise.
Radon forms naturally from the breakdown of uranium in soil and rock. It can seep into homes through cracks in foundations, basements, crawl spaces, and sump pumps. Long-term exposure significantly increases the risk of lung cancer, even for non-smokers.
Health officials stress that testing is the only way to know if a home has elevated radon levels. Low-cost test kits are widely available online and at home improvement stores, and some local health departments offer free or discounted kits during Radon Action Month.
If elevated levels are detected, mitigation systems can reduce radon concentrations by venting the gas safely outside. According to the American Lung Association, professional mitigation can lower radon levels by up to 99%.
Residents are encouraged to learn more about testing and mitigation options by visiting lung.org/radon.
Public health leaders say early detection can make a lifesaving difference.
