Radon Standards and Recommendations for Builders and Contractors

It is important to consider radon during construction beacuse radon-resistant features have many benefits. When installed properly in new homes, radon reduction techniques work well, make upgrading easy, and create a more energy-efficent home. These methods are also cost effective and preventative as opposed to solving a radon problem in the future. Radon-resistant features may include a gas-permeable layer, plastic sheeting, sealing and caulking, a vent pipe, or junction boxes.

Radon reduction systems also need occasional maintenance to ensure they are working properly, and it is a common practice to retest a building after a reduction technique and every two years to be sure radon levels are low.

Further information is available on the EPA radon website. There is currently no required, state-specific certification in Texas. However, the EPA only recommends NRPP-certified radon inspectors and mitigators.

Standards and protocols for conducting radon measurement and mitigation activities have been available since the early 1990s and were developed in several ways: First, by EPA with radon industry input, second, under the ASTM standards development process, and third, by the ANSI-recognized American Association of Radon Scientists and Technologists (AARST) Consortium on National Radon Standards.
