Radon (RN-222), naturally released from underground, is the second leading cause of lung cancer for at-risk groups after smoking, and the leading cause of lung cancer. This research aims to investigate the relationship between housing characteristics and indoor radon levels. Indoor radon data (1993 – 2013) were obtained from the DeKalb County Board of Health alongside housing characteristics sourced from the DeKalb County Tax Assessor. Chi-square tests, logistic regression, and bivariate analysis were used to examine the housing risk factors. The results indicate a correlation between high radon concentrations, and homes constructed of brick, with a basement foundation and centralized heating and air systems. Analysis of geological data revealed no significant connection to elevated radon levels.
