Analysis of Paraho oil shale products and effluents: an example of the multi-technique approach

Description: Inorganic analysis of solid, liquid and gaseous samples from the Paraho Semiworks Retort was completed using a multitechnique approach. The data were statistically analyzed to determine both the precision of each method and to see how closely the various techniques compared. The data were also used to determine the redistribution of 31 trace and major elements in the various effluents, including the offgas for the Paraho Retort operating in the direct mode. The computed mass balances show that … more

Tellurium interference in /sup 129/I activation analysis

Description: Measurement of /sup 129/I at low levels is required for effluent control, environmental assessment and tracer studies in the natural environment. Low level /sup 129/I analysis has also been used for measurement of natural-fission-produced /sup 129/I in minerals and ores as well as meteorites. The most sensitive method for /sup 129/I measurements is neutron activation analysis of iodine separated from a suitable sample. Minimum sample processing prior to neutron activation is desirable in order … more

Neutron induced gamma spectrometry for on-line compositional analysis in coal conversion and fluidized-bed combustion plants

Description: Nuclear techniques involving relatively penetrating radiation may offer the possibility of non-invasive, continuous on-line instrumental monitoring which is representative of the full process stream. Prompt gamma rays following neutron capture are particularly attractive because the penetrating power of the neutrons and the, typically several MeV, capture gammas makes possible interrogation of material within a pipe. We are evaluating neutron capture gamma techniques for this application, both … more

In-vivo neutron activation analysis: principles and clinical applications

Description: In vivo neutron activation has opened a new era of both clinical diagnosis and therapy evaluation, and investigation into and modelling of body composition. The techniques are new, but it is already clear that considerable strides can be made in increasing accuracy and precision, increasing the number of elements susceptible to measurement, enhancing uniformity, and reducing the dose required for the measurement. The work presently underway will yield significant data on a variety of environmen… more

Study of coal oxidation by charged particle activation analysis

Description: The technique of Charged Particle Activation Analysis (CPAA) was applied to study the characteristics of low temperature oxidation of coal. The following parameters were investigated: the kinetics of the adsorption of oxygen containing species; the elemental composition of the oxide layer and how deeply it extends into the particle; and the number of reactive sites on or in the surface. The results of this study are in agreement with those of other laboratories. These are summarized as follows:… more

Effect of physical activity on body composition

Description: It has been noted that the deleterious effects on bone calcium of prolonged periods of inactivity, such as bed rest, are halted following resumption of activity. It would seem possible in light of the observations that have been made, that exercise may stimulate bone formation and perhaps counter, to some extent, bone loss as observed in the osteoporosis of aging. The present study was designed to determine the relation between total body calcium, total body potassium and bone mineral content o… more

Orientation study of the Lake Sunapee area, New Hampshire. National Uranium Resource Evaluation Program

Description: An orientation study was conducted in the area of Lake Sunapee, New Hampshire, in preparation for a hydrogeochemical and stream sediment reconnaissance in glacial terrain. The study was carried out by the Savannah River Laboratory as part of the National Uranium Resource Evaluation (NURE). Ground water, lake water, stream water, lake sediment, and stream sediment samples were collected at 188 sites. The concentrations of uranium and other elements were determined by neutron activation analysis.… more

Elko 1/sup 0/ x 2/sup 0/ NTMS area: Nevada and Utah. Data report

Description: Results of ground water and surface sediment reconnaissance in the National Topographic Map Series (NTMS) Elko 1/sup 0/ x 2/sup 0/ quadrangle are presented. The target sampling density was one site per 12 square kilometers. This resulted in 1713 sediment samples being collected; however, dry conditions and sparce population contributed to the relatively small number of ground water (154) samples collected. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in … more

Practical applications of activation analysis and other nuclear techniques

Description: Neeutron activation analysis (NAA) is a versatile, sensitive multielement, usually nondestructive analytical technique used to determine elemental concentrations in a variety of materials. Samples are irradiated with neutrons in a nuclear reactor, removed, and for the nondestructive technique, the induced radioactivity measured. This measurement of ..gamma.. rays emitted from specific radionuclides makes possible the quantitative determination of elements present. The method is described, advan… more

Kinetic and infrared study of the effect of metal crystallite size and metal-support interactions on CO hydrogenation reactions: a third-year progress report

Description: Platinum and palladium supported on four different oxide materials - SiO/sub 2/, Al/sub 2/O/sub 3/, SiO/sub 2/-Al/sub 2/O/sub 3/, and TiO/sub 2/ - have been studied in depth. Different preparative techniques were utilized to vary metal particle size and change the state of the metal. For example, Pt and Pd deposited on TiO/sub 2/ and reduced at low temperatures (175 to 200/sup 0/C) exhibit normal adsorption behavior, whereas these same catalysts reduced at a high temperature (500/sup 0/C) trans… more

An Evaluation of the Uranium Contamination on the Surfaces of Alclad Uranium-Aluminum Alloy Research Reactor Fuel Plates

Description: Reported radioactivity in the Low-Intensity Test Reactor (LITR) water coolant traceable to uranium contamination on the surfaces of the alclad uranium-- aluminum plate-tyne fuel element led to an investigation to determine the sources of uranium contamination on the fuel plate surfaces. Two possible contributors to surface contamination are external sources such as rolling-mill equipment, the most obvious, and diffusion of uranium from the uranium-aluminum alloy fuel into the aluminum cladding.… more
