Abstract:

An aeroradioactivity survey of approximately 8000 square miles near Washington, D. C. was made by the U. S. Geological Survey on behalf of the U. S. Atomic Energy Commission. Radioactivity profiles were obtained using scintillation-detection equipment along parallel, mile-spaced, east-west flight lines approximately 500 ft above the ground. A map of aeroradioactivity units compiled from the profiles shows a wide range of radioactivity and a generally excellent correlation of radioactivity to areal geology. Parts of four physiographic provinces were covered the Coastal Plain, Piedmont, Blue Ridge, and Appalachian Valley of the Ridge and Valley province. Radioactivity units for each province have characteristic values and a pattern that reflects the geologic structure.
