The report gives results of a project to investigate, analyze, and develop radon-resistant construction guidelines that are consistent with other building codes and that could be applied to Florida. A literature search resulted in information on radon remediation techniques, new construction methods, and existing radon-resistant building codes such as those in Sweden and Canada. The identified techniques were amended, modified, or supplemented for incorporation into draft model guidelines for new construction in format consistent with the Southern Building Code Congress International, Inc.'s Standard Building Code. A technical review advisory committee formed during development of the guidelines, provided input and recommended changes to the draft guidelines. Although the project has resulted in guidelines for recommended construction practices, they should be coupled with a carefully planned and implemented program of experimentation. Eventually, this approach will lead to building code provisions that are scientifically defensible, cost effective, reliable, and easily incorporated into standard construction practice.
