RECOMMENDED FOUNDATION FILL MATERIALS CONSTRUCTION STANDARD OF THE FLORIDA RADON RESEARCH PROGRAM
Rogers, V. C. AND K. K. Nielson. RECOMMENDED FOUNDATION FILL MATERIALS CONSTRUCTION STANDARD OF THE FLORIDA RADON RESEARCH PROGRAM. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/8-91/206 (NTIS 92-105865), 1991.
The report summarizes the technical basis for a recommended foundation fill materials standard for new construction houses in Florida. he radon-control construction standard was developed by the Florida Radon Research Program (FRRP). ill material standards are formulated for: (1) natural foundation soils, (2) fill materials or layered natural soils, and (3) foundation backfill materials. tandards for building materials and testing procedures are also set forth. Soil standards are based on allowable entry rate of radon into a dwelling that is consistent with an indoor radon concentration of 2 pCi/L for mane average dwelling conditions. adium concentrations for over 700 undisturbed Florida soils averaged 0.6 pCi/g and ranged from 0.1 to 2.9 pCi/g. adon emanation coefficients range from 0.1 to 0.45 for most soils.
