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.

From abstract: The Legin group area comprises five privately owned claims, nine Government claims, and some public land. The area is in parts of secs. 28 and 29, T. 43 N., R. 19 W., New Mexico principal meridian, San Miguel County, Colo. It is about 45 miles from the Government mill at Monticello, Utah, and 50 miles from the Vanadium Corporation of America mill at Naturita, Colo. The Legin group area has yielded a total production of more than 18,000 short tons of carnotite ore that averaged 0.32 percent U30 and 2.5 percent V 205 . Most of this production was accomplished during the years from 1935 to 1944, and from 1949 to October 1951.

Report discussing the exploration of the Upper group area in San Miguel County, Colorado, and the investigation of carnotite ores produced from this area.

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.
