Crawl space houses can be defined as those in which a part or all of the living areas of the house are built over an enclosed area containing exposed earth. Clearance in this enclosed area can vary with the house type and site geometry from a few inches below the floor joists to several fee. In most cases the clearance is sufficient so that access can be gained through the outside wall of the house foundation. Prior to the collection of recent radon data, crawl spaces were considered to be a viable alternative for radon control in new construction. The houses for this demonstration were selected from respondents to a media announcement for homeowners whose houses had previously been tested and found to contain elevated levels of radon (greater than 4 pCi/1). From approximately 100 respondents, 15 houses were selected to be included in the mitigation demonstration program. The houses selected included: nine crawl space (C/S) houses, three houses with basements converted from crawl spaces, two combination basement/crawl space houses, and one slab-below-grade house. The results of mitigation efforts on the crawl space houses are presented in this paper.
