The Texas Department of State Health Services (DSHS) is now offering free short term radon test kits for state residents.
According to the US Enivornmental Protection Agency (EPA), radon levels in Texas are quite low, and only a few areas have even a "moderate radon potential". But, you sure can't beat free. I mean, even the envelope you get with the kit to send in your test for interpretation of results has it's postage paid!
There's really no reason not to get and use the test kit.
So, if you're a Texan, contact the DSHS for more information. Their free phone number is 1-800-293-0753. Or, you can email them.
