Radon Potential, Geologic Formations, and Lung Cancer Risk

Exposure to radon is associated with approximately 10% of U.S. lung cancer cases. Geologic rock units have varying concentrations of uranium, producing fluctuating amounts of radon. This exploratory study examined the spatial and statistical associations between radon values and geological formations to illustrate potential population-level lung cancer risk from radon exposure.

•We examine spatial and statistical associations between radon and rock formations.
•Observed radon levels vary significantly by geologic formation category.
•Four rock types are associated with high radon levels.
•Mapping both rock formations and radon values may be better than radon alone.
