Aeroradioactivity Survey and Geology of the Gnome (Carlsbad) Area, New Mexico and Texas (ARMS-I)
Abstract
An aeroradioactivity survey of about 7000 square miles around the GNOME test site near Carlsbad, N. Mex., was made by the U. S. Geological Survey in cooperation with the Division of Biology and Medicine, U. S. Atomic Energy Commission. The project was flown along east-west flight lines approximately 500 ft above the ground. Flight lines were one mile apart in the central part of the area and two miles apart elsewhere. Aeroradioactivity contacts shown on a 1:250,000 map delineate areas of similar radioactivity. The radioactivity values, to which a cosmic correction has been applied, are shown in counts per second (cps), and have been corrected for deviations from the 500 ft surveying altitude. The GNOME area includes parts of three physiographic regions: the Llano Estacado and Pecos lowlands sections of the Great Plains, and the foothills and mountains. The Guadalupe Mountains lie west of Carlsbad, and the Delaware Mountains lie along the southwestern edge of the area. The radioactivity of the GNOME area is low and ranges from 50 to 600 cps. The Llano Estacado portion of the area ranges from 100 to 400 cps; the Pecos lowlands from 50 to 600 cps; and the foothills and mountains from 200 to 600 cps.
