Aeroradioactivity Survey and Areal Geology of Parts of East-Central New York and West-Central New England (ARMS-I)
Abstract
An airborne gamma-radiation survey of Connecticut, Rhode Island, and parts of New York, Massachusetts, New Hampshire, and Vermont was made during the period from 1958 through 1960 by the U. S. Geological Survey in cooperation with the Division of Biology and Medicine, U. S. Atomic Energy Commission. Results of the survey indicate that a wide range of natural radioactivity exists and that the levels are closely related to the type of bedrock underlying glacial material, and subordinately to the glacial material. This report discusses the radioactivity and correlates the data with the areal geology of the northern portion of the area surveyed. The southern portion of the area is discussed in CEX-58.4.6. The area was traversed with parallel flight lines flown 500 ft above the ground and spaced at 1-mile intervals. Continuous aeroradioactivity profiles were obtained with scintillation detection equipment installed in a twin-engine aircraft. A map of radioactivity units was prepared from the profiles. Parts of four physiographic provinces are included in the survey area: the Appalachian Plateau province underlain by relatively flat-lying Paleozoic shale, sandstone, and limestone; the Valley and Ridge province underlain by weakly folded Paleozoic shale, sandstone, limestone, and dolomite; and the New England and Adirondack provinces, underlain chiefly by highly deformed Precambrian and Paleozoic schist, gneiss, and amphibolite. Bedrock in the survey area is mantled with unconsolidated glacial deposits that range in thickness from 0 to more than 200 ft.
