The treatment for some thyroid carcinomas involves surgically removing the thyroid gland and administering the radiopharmaceutical Sodium iodide-{sup 131}I (NaI). A diagnostic dose of NaI is given to the patient to determine if remnant tissue from the gland remains or larger doses are administered in order to treat the malignant tissue. Past research regarding NaI uptake and retention in euthyroid individuals (normal functioning thyroid) reveal that radioiodine concentrates mainly in the thyroid tissue and the remaining material is excreted from the body. The majority of radioiodine in athyroid (without thyroid) individuals is also eliminated from the body; however, there has been recent evidence of a long-term retention phase for individuals with no radioiodine concentrating tissue. The general purpose of this study was to develop a kinetic model and estimate the absorbed dose to athyroid individuals regarding the distribution and retention of NaI.

The Estes Gulch disposal site is approximately 10 kilometers (6 miles) north of the town of Rifle, off State Highway 13 on Federal land administered by the Bureau of Land Management. The Department of Energy (DOE) will transport the residual radioactive materials (RRM) by truck to the Estes Gulch disposal site via State Highway 13 and place it in a partially below-grade disposal cell. The RRM will be covered by an earthen radon barrier, frost protection layers, and a rock erosion protection layer. A toe ditch and other features will also be constructed to control erosion at the disposal site. After removal of the RRM and disposal at the Estes Gulch site, the disturbed areas at all three sites will be backfilled with clean soils, contoured to facilitate surface drainage, and revegetated. Wetlands areas destroyed at the former Rifle processing sites will be compensated for by the incorporation of now wetlands into the revegetation plan at the New Rifle site. The UMTRA Project Office, supported by the Remedial Action Contractor (RAC) and the Technical Assistance Contractor (TAC), oversees the implementation of the MAP. The RAC executes mitigation measures in the field. The TAC provides monitoring of the mitigation actions in …

From Introduction: "The Leadville Quadrangle, Colorado (Fig. 1), was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. Geologic environments were placed into one of three categories--favorable, unfavorable, or unevaluated--based on National Uranium Resource Evaluation (NURE) program."

Appendices containing supplementary analytical data of uranium occurrences, chemical analyses of stream-sediment, rock, and soil samples, and tabulated radiometric and gamma-ray anomaly data to accompany a report on U.S uranium resources in the Leadville Quadrangle, Colorado.

"Field and laboratory data are presented for 1,416 water samples from the Limon Quadrangle, Colorado. The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee."

Abstract: Nine artificial-recharge pits were excavated in the alluvium in upper Black Squirrel Creek basin, Jimmy Campy Valley, and in the alluvium overlying the Widefield aquifer in Fountain Valley. Each artificial-recharge site was instrumented to measure inflow, stage fluctuations, and water-table fluctuations. Artificial-recharge tests conducted in upper Black Squirrel Creek basin indicated that the average adjusted rates of infiltration for the three sites ranged from 1.6 to 2.4 feet (0.5 to 0.7 meter) per day. Tests conducted in Jimmy Camp Valley indicated that the average adjusted rates of infiltration for the two sites ranged from 3.8 to 24.7 feet (1.2 to 7.5 meters) per day. Tests conducted on the Widefield aquifer indicated that the average adjusted rates of infiltration for four sites ranged from 2.3 to 12.9 feet (0.7 to 3.9 meters) per day.

Abstract: The Lake Minnequa area, located immediately south of the Arkansas River, is mantled with as much as 46 feet (14 meters) of alluvium covering bedrock of Pierre Shale and Niobrara Formation. Surface water enters the area by the Minnequa Canal and the St. Charles Flood Ditch. The water is stored in Lake Minnequa and other reservoirs. Seepage from St. Charles Reservoirs No. 2 and No. 3 is the major source of water to the alluvial aquifer. The depth of the water table ranges from 0 to 40 feet (0 to 12.2 meters). A 0.5-square-mile (1.3-square-kilometers) area immediately south of Lake Minnequa has a water table less than 6 feet (1.8 meters) below land surface. Lake Minnequa is the principal cause of the shallow water table and resulting waterlogged soil. The bedrock hill east of Lake Minnequa and ground-water flow also contribute to the problem. To eliminate the waterlogging problem, the water table would have to be at least 6 feet (1.8 meters) below land surface. Possible alternatives for eliminating the problem include lowering the water, level in Lake Minnequa, placing a network of dewaterinq wells, or constructing a drainage system in the waterlogged area.
