Description:
The report describes the approach, methods, and detailed data used to prepare soil radon potential maps of 12 counties in North-Central Florida. he maps were developed under the Florida Radon Research Program to provide a scientific basis for implementing radon-protective building construction standards in areas of elevated risk, and avoiding unnecessary regulations in areas of low radon risk. alculated soil radon potentials reflect geographic variations by modeling the potentials as the rate of radon entry into a reference house that is successively modeled on the soils in each radon map region. ndividual soil profile properties are defined by horizon from county soil survey data. adon source properties are defined from aeroradiometric data and from soil radium and radon emanation measurements. alculated rates of radon entry into the reference house are grouped into tiers for display on radon potential maps. omparison of the calculated radon entry rates with indoor radon data yields a geometric standard deviation of 2.1, and indicates that the reference house is consistent with the aggregate properties of the Florida houses in the comparison.
