From abstract: During July-August 1976, water and sediments were collected for the Los Alamos Scientific Laboratory from streams and lakes over an area of -100 000 km2 around Kotzebue, Alaska. The sampling was by helicopter, as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) sponsored by the US ERDA. It was done according to rigorous, but simple, written procedures, at a nominal density of one location per 23 km 2, and included the 1400- to 1900-km2 area proposed for the Cape Krusenstern National Monument. All the samples would normally have been analyzed for uranium and presented in a regular HSSR report. However, due to an interest in the proposed Monument area, the Anchorage office of the Department of Interior, Bureau of Mines, provided funds for multielement analyses on the sediments taken from there. Consequently, in addition to the routine field data and uranium determinations for waters and/or sediments from 89 locations sampled over the proposed Cape Krusenstern Monument, the results of analyses of 44 additional elements in 77 of the sediments from there are provided. Sample locations are shown on a 1:250 000-scale plate. The data and descriptions of the methods used are in appendices.

From summary: This report contains data collected during a geochemical survey for uranium in the Ashton National Topographic Map Series (NTMS) quadrangle of eastern Idaho, southwestern Montana, and northwestern Wyoming (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide lydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From summary: This report contains data collected during a geochemical survey for uranium in the St. Johns National Topographic Map Series (NTMS) quadrangle of Arizona/New Mexico (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From summary: This report contains data collected during a geochemical survey for uranium in the Billings National Topographic Map Series (NTMS) quadrangle of south-central Montana (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From introduction: This report presents uranium and other elemental data resulting from the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Thermopolis National Topographic Map Series (NTMS) quadrangle, Wyoming, by the Los Alamos Scientific Laboratory (LASL).

The stability of a linear pinch is investigated by means of the "6W" formalism of E. A. Frieman. It turns out that when attention is confined to the surface layers of the plasma, convenient stability criteria can be deduced for very general cylindrically symmetric distributions of magnetic field and plasma.

The use of quartz tubing for sampling molten plutonium and for casting rods is described. These procedures offer cheap and easy-to-use methods for obtaining molten samples and for casting long rods with small diameters.

Thermal neutron measurements made on five weapons during Operation Teapot indicated that these neutrons contribute at most 2 per cent of the total neutron dose in air. However, the total fluxes were high and thermal neutrons may become important under shielding conditions and may significantly affect the responses of the film badges and certain sensitive dose detectors, especially when the neutron to gamma flux ratio is high.

A spectrophotometric method is described for the determination of aluminum in plutonium-aluminum alloys. The alloys are dissolved in parchloric acid and the diluted solution electrolyzed using a mercury cathode to remove any iron present which would interfere in the subsequent analysis. Then plutonium is then separated from the aluminum by precipitation as the insoluble iodate, and the aluminum determined in the supernatant solution using aluminon as a color reagent.

The transmissions of neutrons through spherical shells of normal uranium, oralloy, and Pu239 are reported. One group of measurements was made using a pure fission neutron source produced by thermal neutrons. The other group of measurements was made using monoenergetic neutrons. From both groups of measurements, the inelastic scattering cross sections have been determined according to methods developed in Los Alamos Scientific Laboratory Report LA-1429 (Jaunary 1955).

Due to laboratory interest in devices capable of production of high current with short rise times in gaseous discharges (plasmas), an experimental machine has been built and tested to obtain data applicable to the design of a high gradient magnetic induction machine. This machine consists of a condenser type energy storage bank air core coupled to a toroid in which the plasma is produced. It has been used to determine circuit parameters and the effect of these parameters on the plasma.
