Name: Radon Potential Areas

Display Field: PROVINCE

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This data contains polygon features representing areas of radon potential within Fairfax County. These areas were developed by short-term test results from a study conducted by the Fairfax County Health Department during the winters of 1986-87 and 1987-88.
