Although Texas covers a large geographic area its geology is such that only a small number of localized areas have elevated radon concentrations. Texas homes on the average have less than 1.0 pCi/L of radon, one-fourth the EPA action-level. Locations where radon may be an issue are in well-defined regions: the Llano uplift, which is a granite formation in central Texas, and parts of the west Texas regions including the Panhandle and the Big Bend region. Even though the need for assistance on indoor radon issues is modest, Texas maintains a helpful website www.dshs.state.tx.us/radiation/radon.shtm with facts about testing and mitigation of radon. The website also shows the results of an initial study of state’s potential radon issues.
For residents of Texas who have general questions or concerns about radon, the Texas Department of State Health Services’s contact person is Ruben Cortez, who may be reached by email: Ruben.Cortex@dshs.state.tx.us or by
telephone: 512- 834-6770 ext. 2004.
