The report gives results of an analysis of the feasibility and approach for developing statewide maps of radon potentials in Florida. The maps would provide a geographic basis for implementing new radon-protective building construction standards to reduce public health risks from exposure to radon. In this new mapping approach, variations in indoor radon are partitioned by source, house, and time variations. Source variations are partitioned from house variations by compiling radon entry rates for a reference house that is modeled as though located on varying layered soils that represent the source ariations throughout the state. House variations are represented from existing indoor radon data after normalizing to the source potential at each location. Time variations are minimized by using invariant or long-term parameters. Two kinds of maps would result from this approach's radon source maps and radon probability maps. The expected indoor radon concentrations could be computed from a particular source datum and nominal house characteristics.
