Nature of atmospheric dust. Progress report to January 15, 1955

Description: Optical microscopic examination of air- and rain-borne dust shows most of the particles to be less than one micron in diameter. Electron microscopic examination of the same dust shows predominantly clusters of particles whose individual diameters are in the range 200 to 1000 A. The residue obtained by filtering rain water through a millipore filter is found to be slightly radioactive in more than half the cases observed.

Fall-Out Studies with a Laboratory Controlled Model

Description: From abstract: "To seek information for a better understanding of the phenomena involved in fall-out, a fireball effect was simulated in a small closed room by subjecting various materials to a high-current (~360 amp.) are produced between graphite electrodes, and anode being impregnated with radioactive materials. The time duration of the arc, power dissipated, and distance from the samples were controlled. The radioactivity which remained airborne, that which settled out onto the floor and it… more

The Effect of Coenzyme A on the Metabolic Oxidation of LabeledFatty Acids: Rate Studies, Instrumentation, and Liver Fractionation

Description: The effect of pantothenic acid deficiency on the rate of C{sup 14}O{sub 2} excretion and on distribution of radioactivity in liver fractions has been studied in rats given sodium acetate-2-C{sup 14} and sodium heptanoate-7-C{sup 14} The rate of excretion of breath C{sub 14}O has been measured by use of a method in which a sensitive ionization chamber and electrometer directly and continuously record carbon-14 excretion. The labeled fatty acids are more rapidly metabolized to C{sup 14}O{sub 2} i… more

Reactor Development Quarterly Progress Report. 4000 Program

Description: The status of Experimenial Boiling Water Reactor development is reviewed. Shell testing, control mechanism development, fuel corrosion, and dimensional stability studies, and design consideration to facilitate D/sub 2/O operation are discussed. Fuel plate and subassembly fabrication, corrosion, and radiation damage studies were continued. Reactor water filtration, purification, and induced activity are considered. High-temperaiure operational tests were run on Experimental Breeder Reactor mecha… more

WORLD-WIDE FALLOUT FROM OPERATION CASTLE

Description: A world-wide network of gummed film stations was established to monitor fall-out following Operation Castle. Although meteorological data were poor, a general connection of tropospheric flow patterns with observed fall-out was evident. There was a tendency for debris to remain in tropical latitudes, with incursions into the temperate regions associated with meteorological disturbances of the predominantly zonal flow. As the season advanced, such incursions became more evident. Outside of the tr… more

Radioactivity Investigations at Ear Mountain, Seward Peninsula, Alaska, 1945

Description: From abstract: Radioactive material in apparently significant amounts was recognized in heavy-mineral concentrates from the gravels of four streams that head in Ear Mountain, Alaska, when collections of the United States Geological Survey were examined for radioactivity in the winter of 1944-45. This area, on the north side of the Seward Peninsula, attracted attention in 1901-02 when cassiterite was discovered in the streams. Subsequent attempts were made to develop copper- and tin-bearing lode… more

Shock Hydrodynamics of an Exploding Steam Pressure Vessel. Final Report

Description: The purpose of these investigations is to determine, grossly and simply, if a shock hazard exists from an explosive failure of the pressurizer vessel within the vapor container. Because of the geographical location of the reactor, an explosive failure which ruptured the vapor container might release radioactive contamination from the reactor to nearby inhabited communities. The study is considered more as a generic problem than of a specific design and is concerned with the shock hydrodynamics … more

RADIOACTIVE WASTE ECONOMICS: OPTIMUM STORAGE TIME PRIOR TO SHIPPING TO DISPOSAL SITE

Description: The economics of waste disposal by pit storage when the geological location of the pits does not coincide with the location of the processing plant are considered. Optimum cooling times before shipment were determined for 250gallon batches of Purex-type waste. Three distances between processing and disposal sites, and three unit storage costs were considered. It was concluded that as the storage cost increases it becomes economical to ship shorter-cooled waste, and as the shipping distance incr… more
