Using cancer registry data from Utah, Connecticut, Iowa, and New Mexico, researchers compared lung cancer incidence between counties classified as high and low radon risk across nearly five decades. After adjusting for county level smoking prevalence, high radon risk counties showed about 13.5 additional lung cancer cases per 100,000 people per year, reinforcing residential radon as an independent contributor to lung cancer.
