Environmental and Public Safety During In-Situ Uranium Recovery
October 26, 2007 - 9:36 AM
The U.S. Nuclear Regulatory Commission (NRC) oversees and regulates the process of in-situ uranium recovery. However, Colorado is an ‘Agreement State,’ meaning that the Colorado Department of Public Health and Environment (CDPHE) has entered into an agreement with NRC to oversee all uranium licensing and permitting on NRC’s behalf....
Groundwater Protection and Restoration During In-Situ Uranium Recovery at the Centennial Project
October 26, 2007 - 9:36 AM
What preliminary studies and sampling will be completed in order to determine the baseline conditions of the aquifer? Powertech crews have been collecting data at the Centennial Project since April 2007. Well pump tests will be performed to define the hydrological characteristics of the ore zone, obtain information about the direction and velocity of ground water flow, and identify the composition, porosity, permeability, and hydraulic gradients of the ore zone and adjacent geologic strata....

Regulation and Permitting of In-Situ Uranium Recovery in Colorado
October 26, 2007 - 9:34 AM
In-situ uranium recovery is a highly regulated at the federal, state and local levels. In fact, the process is subject to more than three-dozen major and minor federal environmental laws. In addition, Powertech (USA) Inc. must submit extensive permit applications for multiple government regulatory agencies before any mining activities can begin. This Fact Sheet outlines the overall permitting process and timeline at each level. ...
Radiation Risk in Perspective
October 26, 2007 - 9:33 AM
Radiation is everywhere. Radiation is energy. There are two forms of radiation: non-ionizing radiation and ionizing. Non-ionizing radiation includes television and radio signals and does the cooking in your microwave. Ionizing radiation emanates from radioactive material, X-ray machines and cosmic rays. For this discussion, radiation refers to the ionizing type only....

Mortality among a cohort of uranium mill workers: an update
October 25, 2007 - 4:35 PM
In the United States, mining and milling of uranium ores to
recover uranium for nuclear weapons began during World
War II to support the Manhattan Project. Uranium bearing
ores had been mined previously on a small scale, but mainly
for the recovery of vanadium. Continued development and
expansion of the industry after the war was promoted by a
domestic uranium concentrate procurement programme that
was established by the Atomic Energy Commission in 1947.1
As early as 1949, health officials became concerned about the
potential health risks associated with uranium mining and
milling.2
The health...
