Flight Areas for an Aerial Radiological Survey of Abandoned Uranium Mines, Navajo Nation, 1994-1999, USEPA and USDOE
Description
This polygon shapefile documents the extent of the aerial radiological surveys of 41 potential uranium mining areas (1,144 square miles) within the Navajo Nation that were conducted during the period from October 1994 through October 1999. The US Environmental Protection Agency (USEPA) Region 9 funded the surveys and the US Department of Energy (USDOE) Remote Sensing Laboratory (RSL) in Las Vegas, Nevada conducted the aerial surveys. The aerial survey data were used to characterize the overall radioactivity and excess Bismuth 214 levels within the surveyed areas. Bismuth 214 is an indicator of uranium ore deposits and/or uranium mines. Fourteen attributes about each survey are included.
