Radon Protection Maps:
You may examine separately the Department of Business and Professional Regulation (Formerly within the Department of Community Affairs) radon protection maps by county for large buildings and for single family homes and duplexes (residences). These maps describe the areas of the state where added radon resistant measures beyond the current energy efficient building code are needed to prevent indoor radon problems. Currently these standards are voluntary. It would take a majority of the building permit issuing agencies in any county to adopt them for the standards to become a require code within that county. Only those counties that have areas where added radon resistant features are recommended have maps.
These maps say nothing about the prevalence of existing radon problems or the odds of an existing building having a radon problem. The only way to know if a building has a radon problem is to test.
These maps were developed by the program mapping group as part of the Florida Radon Research Project, and published in 1995, and are currently used by the radon program. The program mapping group consisted of:
