This book examines uranium mining and management in the United States with a focus on federal considerations. From 2005 to 2007, uranium prices increased from about $20 a pound to over $140 a pound, which led to renewed interest in uranium mining, both exploration and extraction, on federal land in the U.S. In early 2012, thousands of claims have been filed to explore for and potentially extract uranium on federal land. This increase in claims filed, has raised concerns about the potential impacts that an increased level of uranium exploration and extraction could have on the environment. During uranium extraction, the waste rock piles that are formed can introduce radionuclides (such as radium) and heavy metals (such as selenium and arsenic) into the environment. Before the mid-1970s, many mines on federal land, were abandoned without any reclamation, leaving a costly legacy of abandoned mines that pose potential health, safety, and environmental hazards.
