Radon-resistant Construction Techniques for New Residential Construction: Technical Guidance (EPA/625/2-91/032) February 1991

Growing concern about the risks posed by indoor radon has underscored the need for dependable radon-resistant residential construction techniques. The U.S. Environmental Protection Agency has responded to this public health concern by developing and demonstrating a variety of methods to reduce radon in existing houses. Many of these methods could be applied during construction, involve reduced labor and financial investments, and provide greater homeowner satisfaction and safety than a radon-reduction technique installed after the home is built and occupied.

Some of the techniques mentioned in this manual have not been demonstrated fully in new home construction. However, the soil ventilation techniques described have been extensively tested in existing homes and show good potential for application in new construction.

This manual provides a basic understanding of the types of products and systems that are available and being used to reduce radon concentrations indoors. The reader will be able to select radon-resistant products and systems that will be most applicable to a particular situation. EPA's intent is not to rate similar products made by different manufacturers or to provide a stock radon-resistant package.
