The CLOVER Study
Climate Impact on Lung Cancer via Exposure to Radon
The CLOVER Study is working to better understand how radon affects people across North Carolina, especially in connection with climate change. We’re looking at how radon exposure may vary in different communities and homes, and how it might contribute to lung cancer — particularly among vulnerable populations who may be at higher risk. Did you know that lung cancer isn’t just caused by smoking? In fact, radon gas — a naturally occurring substance that can build up in homes — is the second leading cause of lung cancer in North Carolina.
What is Radon?
Radon is a colorless, odorless gas released from the breakdown of rocks and minerals in the soil. It can seep into homes and build up over time, increasing the risk of lung cancer. Radon is the second leading cause of lung cancer and accounts for up to 15% of cases nationwide. Climate changes—like shifting soil conditions and more extreme weather—can increase how much radon enters buildings, leading to higher indoor concentrations over time. The North Carolina Department of Human and Health Services (NCDHHS) recommends testing for radon at most every 5 years. For more information and video information on radon, visit the NCDHHS website.
By measuring the impact of radon-related lung cancer, the CLOVER Study aims to inform state policies that improve awareness, expand access to radon testing and mitigation, and ultimately reduce lung cancer rates across North Carolina. Our CLOVER team has been active across the state, attending community fairs, conferences, and partnering with nonprofits to distribute free radon test kits directly to residents. After testing, participants receive their results and are invited to complete a brief survey to help us better understand radon exposure and its impact. This community-driven data is essential to shaping future health policies and protecting families from radon-related lung cancer.
