ROE Radon Data
The polygon dataset represents predicted indoor radon screening levels in counties across the United States. These data were provided by EPA’s Office of Radiation and Indoor Air as an Excel spreadsheet. In order to produce the Web mapping application, the Excel file was joined with a shapefile of U.S. county boundaries downloaded from the U.S. Census Bureau. Those two sets of data were then converted into a single polygon feature class inside a file geodatabase.
These data were created to be used for the U.S. Environmental Protection Agency's Report on the Environment website.
