  • Pulse reader for ionization chambers

    Creator:
    Boothe, Gary F.
    Abstract:
    A pulse reader for ionization chambers has been developed, tested, and calibrated. An insulated gate field effect transistor (IGFET) was used to detect the pulses and Victoreen Model 362 Pocket Chambers were used as ionization chambers. The energy dependence of the Victoreen Model 362 Pocket Chamber was determined to be...

  • Environmental Effects of Tidal Energy Development

    Creator:
    Polagye, Brian, Van Cleve, Brie, Copping, Andrea, and Kirkendall, Keith
    Abstract:
    This report summarizes the outcomes of a March 22-25, 2010, workshop in Seattle, Washington, on the environmental effects of tidal energy development. The workshop focused on building capabilities to evaluate the environmental effects of tidal energy from turbines placed in the water column throughout the United States. However, it did...

  • Dechlorination of p-chlorophenol on palladium based metal support catalyst

    Creator:
    Moore, Kelley A.
    Abstract:
    Disposal of chlorinated hydrocarbons is a major environmental concern due to the lack of a satisfactory means of safe remediation at all contaminated locations. Current technologies rely primarily on incineration, a process that can lead to dangerous byproducts such as dioxin. If the chlorine substituent can be removed prior to...

  • Addressing Data Resolution in Precision Agriculture

    Creator:
    Kelley, Jason
    Abstract:
    Irrigated agriculture constitutes the greatest consumptive water use globally, so that irrigation efficiency measures are an important part of global efforts to best utilize this limited resource. However, greater irrigation efficiency must be achieved while simultaneously maintaining or increasing crop yields and farming profitability. Incremental water use decisions are made...

  • Quantitative resistance to Puccinia striiformis f. sp. hordei in barley near-isogenic (BISON) lines

    Creator:
    Richardson, Kelley L.
    Abstract:
    Quantitative resistance (QR) to disease is usually more durable than qualitative resistance, but its genetic basis is not well understood. We used the barley/barley stripe rust pathosystem as a model for the characterization of the QR phenotype and associated genomic regions. As an intermediate step in the preparation of near-isogenic...

  • The design, construction and calibration of a low-energy, low exposure-rate ionization chamber

    Creator:
    Clarke, Arthur Porter
    Abstract:
    A low-energy, low-exposure-rate, guarded-field ionization chamber system with a sensitive volume of approximately 1040 cm³ and an exposure-rate range from 60 mR/h to less than 0.5 mR/h was designed, constructed and calibrated. The calibration was effected by constructing and calibrating a 60 cm³ volume transfer chamber of similar design against...

  • The design and construction of an ionization chamber to measure background radiation

    Creator:
    Weaver, Kenneth Earl
    Abstract:
    An ionization chamber was constructed, using a fiberglass wall sphere, for the purpose of measuring background radiation. The system consists of the fiberglass wall chamber, 38.85 liters in volume, air filled, not sealed, used in conjunction with a precision capacitor, nulling voltage supply and electrometer. It was calibrated against a...

  • Scattered radiation from bedside radiographic examinations

    Creator:
    Kellner, JoEllen Gretzinger
    Abstract:
    The purpose of this study was to investigate the distribution and magnitude of scattered radiation from a typical mobile radiographic examination as an aid in evaluating the potential health hazards of the scattered radiation. Also discussed are current radiation protection standards and recommendations for mobile radiography. A Manonite phantom represented...

  • A study of the thermal characteristics of x-ray tube housings

    Creator:
    Stovall, John Walter
    Abstract:
    The relationship of x-ray tube housing temperature to duty cycle was studied for a superficial therapy x-ray installation, a dental radiographic installation, and a rotating-anode medical diagnostic installation. Thermistors were used to measure the tube housing temperature at points selected to be representative of thermal conditions on the surface of...
