Uranium series dating
Geological Survey (USGS) was involved in understanding uranium geology, geochemistry, and resources.
Future website components will include: Uranium and its decay products and associated trace elements create human health and environmental hazards wherever they occur in unusually elevated levels.
With the resurgence of uranium exploration and mining activities in the United States over the past few years, a substantial need for ready access to existing data in the files of the USGS' Energy Program has increased.
S., uranium mine wastes remain at a number of sites throughout the western United States and constitute a significant hazard for casual visitors to the site from gamma exposure and inhalation of windblown dust.Many areas of some western States continue to have exposed unreclaimed uranium mine wastes at former mining sites.The leaching of radionuclides and other elements by precipitation and the erosion of waste piles by wind and runoff are primary mechanisms by which adjacent soils, water, and ecosystems are impacted by uranium mine waste piles, yet very few studies of waste piles have occurred to document whether such processes create hazards beyond the immediate vicinity of the piles.Visitors to underground uranium operations, which are common in many recreational areas of the west, have been exposed to extreme levels of radon.
These hazards have been recognized by responsible Federal and State agencies and reclamation of many uranium mine sites in the west and closure of undergound mine openings has occurred.
The USEPA released guidelines for uranium mine waste cleanup.
