This study analyzes radon measurements across 764 zip codes in West Virginia from 1998 to 2003. Out of the 764 zip codes evaluated, 540 had at least one radon measurement, and 361 had five or more measurements. It was found that 11% of these zip codes exceeded the US EPA's action level of 4 pCi/L for radon levels. Additionally, 19% showed elevated radon measurements based on dominant bedrock type. This research contributes essential insights into the geological factors influencing radon exposure in West Virginia.
