A recent study has found that exposure to radon, a radioactive gas, is associated with an increased risk of stroke. Even moderate concentrations of radon were found to be linked to a higher risk of stroke compared to lower concentrations. Testing for radon in homes is crucial to address this emerging risk factor.
Radon Exposure Linked to Increased Stroke Risk

A recent study has found that exposure to radon, a radioactive gas, is associated with an increased risk of stroke. Even moderate concentrations of radon were found to be linked to a higher risk of stroke compared to lower concentrations.
The study, which focused on middle-aged to older female participants, discovered that even moderate concentrations of radon were associated with a higher risk of stroke compared to those exposed to lower concentrations. While the study does not prove that radon exposure directly causes stroke, it does establish an association between the two.
Importance of Testing for Radon Concentrations
Radon is an invisible and odorless gas that can seep into homes through cracks in walls and floors, construction joints, and gaps around pipes. The lead author of the study, Dr. Eric A. Whitsel, emphasized the importance of testing for radon concentrations in homes. He stated, "Radon is an indoor air pollutant that can only be detected through testing that measures concentrations of the gas in homes."
The research found an increased risk of stroke among participants exposed to radon levels above the recommended threshold set by the Environmental Protection Agency (EPA). Therefore, testing for radon in homes is crucial to address this emerging risk factor and take necessary measures to mitigate its presence.
Study Details and Findings
The study included 158,910 female participants with an average age of 63 who did not have a history of stroke at the beginning of the study. They were followed for an average of 13 years, during which 6,979 strokes occurred. To assess radon exposures, the researchers linked the participants' home addresses to radon concentration data from the U.S. Geological Survey and the EPA.
The findings showed that participants in the highest exposure group had a 14% increased risk of stroke compared to those in the lowest exposure group. The middle group had a 6% increased risk. These results indicate an increased stroke risk even at radon concentrations slightly below the current threshold for recommending radon mitigation to prevent lung cancer.
Limitations and Further Research
It is important to note that this study had limitations, including its focus on only female participants who were middle-aged or older and primarily white. Therefore, the results may not be generalizable to other populations. Further research is necessary to validate these findings and explore the relationship between radon exposure and stroke risk in a broader demographic.
Confirmation of these findings would present an opportunity to improve public health by addressing an emerging risk factor for stroke.
Conclusion
This study highlights the potential link between radon exposure and an increased risk of stroke. While more research is needed to establish a causal relationship, it underscores the importance of testing for radon concentrations in homes and taking necessary measures to mitigate its presence. By addressing this emerging risk factor, public health efforts can potentially reduce the incidence of stroke and improve overall well-being.
