Analysis of monazite, zircon, and apatite from the southeastern Piedmont. National uranium resource evaluation program

Description: Two hundred sixty-three monazite, 191 zircon, and 16 apatite grains from 52 stream-sediment locations in the Southeastern Piedmont were analyzed by electron microprobe for one of the following suites of elements: Ca, La, Ce, Pr, Nd, Sm, Eu, Gd, Er, Dy, Y, Th, U, P, and F, or Ca, La, Ce, Fe, Er, Hf, Y, Th, U, P, Zr, Mg, Al, and Si. Monazite samples that had high uranium or thorium content and zircon samples that had high hafnium or iron content from a total of six locations were reanalyzed to co… more

Little Rock and El Dorado 1/sup 0/ x 2/sup 0/ NTMS quadrangles and adjacent areas, Arkansas: data report (abbreviated)

Description: This abbreviated data report presents results of ground water and stream sediment reconnaissance in the National Topographic Map Series Little Rock 1/sup 0/ x 2/sup 0/ quadrangle (Cleveland, Dallas, and Howard Counties do not have stream sediment analyses); the El Dorado 1/sup 0/ x 2/sup 0/ quadrangle (only Clark County has stream sediment analyses); the western part (Lonoke and Jefferson Counties) of Helena 1/sup 0/ x 2/sup 0/ quadrangle; the southern part (Franklin, Logan, Yell, Perry, Faulkn… more

Effect of organic complexants on the mobility of low-level waste radionuclides in soils: status report

Description: The effects of some organic complexants on the sorption by soil of some elements typical of those present in low-level wastes are being evaluated and procedures are being developed to efficiently obtain valid sorption data. Data have been obtained with Hanford soil and the elements europium, nickel, cobalt, cesium, and strontium. Complexants studied to date include ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), and humic acid. The sorption of cesium and stron… more

Research and development related to the Nevada nuclear waste storage investigations. Progress report, July 1-September 30, 1980

Description: Sorption of americium and plutonium was measured in a controlled, oxygen-free atmosphere and in air on a series of tuff samples. Sorption of plutonium was greater in the controlled atmosphere than in air. Sorption of both elements is higher on zeolitized tuff than devitrified tuff. Sorption of strontium, cesium, barium, cerium, and europium is being measured on tuff samples of mineralogies not previously studied, and samples from the USW-G1 drill hole have been selected for study. Work on the d… more

Sorption-desorption studies on tuff III. A continuation of studies with samples from Jackass Flats and Yucca Mountain, Nevada

Description: This report is the third in a series of reports describing studies of sorption and migration of radionuclides in tuff. The investigations were extended to lithologies of tuff not previously studied. Continuing experiments with uranium, plutonium, and americium are described. The dependence of sorption on the concentration of the sorbing element and on the solution-to-solid ratio was investigated for a number of nuclides and two lithologies. A circulating system was designed for measuring sorpti… more
