Radon in Texas

Is Radon a Problem in Texas?

In Texas, the average indoor radon levels are mostly within national norms; however, when examined on a county-by-county basis, several areas of Texas are identified where local geology is suspected of contributing to the potential for elevated levels of indoor radon.

The Panhandle area of Texas shows moderate to high average levels of radon from first-floor level tests. 

Basement average radon levels (where the basement is the lowest livable floor of the home) are typically higher than first floor indoor radon levels, in some cases significantly higher. Refer to the Texas Indoor Radon Map 2020 Update figures and Executive Summary Report, available below.

For comparison, refer to the 1993 TEXAS - EPA Map of Radon Zones.
