January is National Radon Action Month, a time to highlight an often overlooked health risk and share simple steps North Carolinians can take to help protect their homes and families.
Radon is a naturally occurring radioactive gas that can build up indoors. Because it is colorless, odorless, and tasteless, many people are unaware it may be present in their homes. According to the North Carolina Department of Health and Human Services (NCDHHS), radon is the leading cause of lung cancer among nonsmokers, making awareness and testing an important part of preventive health.
Understanding the health impact of radon
Radon forms from the natural breakdown of uranium in soil and rock. It can enter homes through small openings such as cracks in foundations, crawl spaces, sump pumps, or, in some cases, through water from private wells. When radon becomes trapped indoors and is inhaled over long periods, it can damage lung tissue and increase the risk of lung cancer.
Certain groups face a higher level of risk. People who currently smoke or have smoked in the past are significantly more vulnerable to the harmful effects of radon exposure. Living in a home with elevated radon levels while smoking can increase lung cancer risk by up to 10 times compared to nonsmokers. Research also indicates that children may be more susceptible to the long-term effects of radon exposure than adults.
Radon risk in North Carolina
Radon is a statewide concern. NCDHHS estimates that homes with elevated radon levels can be found in 77 of North Carolina’s 100 counties. Because radon levels can vary widely from one home to another, even within the same neighborhood, testing results from nearby houses do not reliably reflect conditions in an individual home.
Parts of western North Carolina, where many Vaya members live, fall into moderate- to high-risk radon categories due to underlying geology. While this does not mean every home in these areas has unsafe radon levels, it does make testing especially important, particularly for households that rely on private well water.
Testing is the only way to know
Because radon cannot be detected by sight or smell, testing is the only way to determine whether a home has elevated levels. Fortunately, testing is simple and accessible.
Beginning January 1, all North Carolina residents can request free radon test kits through the North Carolina Radon Program, administered by NCDHHS. These kits include clear instructions for collecting a sample and mailing it to a certified laboratory for analysis. Test results can help North Carolinians decide whether additional steps are needed to reduce exposure.
Supporting healthier homes and communities
Radon exposure is a preventable health risk. Identifying elevated levels early and taking appropriate action can significantly reduce exposure and support long-term lung health.
At Vaya Health, supporting whole-person wellness includes sharing information that helps individuals and families make informed decisions about their health and environment. National Radon Action Month is a reminder that small preventive steps, such as testing your home, can play an important role in keeping North Carolina communities healthier and safer.
