  • 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...

  • The distribution of leakage radiation from an unshielded diagnostic-type x-ray tube housing

    Creator:
    Gragg, Royce Lynn
    Abstract:
    The objective of this study was to determine the distribution of leakage radiation from two unshielded diagnostic-type X-ray tube housings. This information was used to determine the shielding required in the housings to bring them into compliance with the definition of a diagnostic-type protective tube housing, as set forth by...

  • 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...

  • 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...

  • Some factors associated with reconciliation decisions among couples with marital problems

    Creator:
    Kelley, Roselene Jensen
    Abstract:
    The purpose of the study was to investigate the nature of marital interaction that occurs at the point at which couples with problems seek assistance from an agency specifically designed to deal with marital problems. Efforts were made to learn more about the nature of the marital relationship in general,...

  • A configuration-interaction calculation of wave functions for certain states of lithium

    Creator:
    Brown, Bert Elwood
    Abstract:
    A configuration-interaction determination of wave functions has been made for the ²S and ²P states of lithium, and for the ¹S and ³S states of the lithium ion. Two 1s, one 2s, one 3s, and two 2p functions served as starting functions for all four states. Results of the total...

  • A critical analysis of wildlife conservation in Oregon

    Creator:
    Rymon, Larry Maring
    Abstract:
    This analysis is the study of Oregon's wildlife resources from the period prior to white settlement up to the present time, including critical projections, based on present trends and expected conditions for both human and wildlife populations in the state up to the year 2010. Prior to white settlement Oregon...

  • A comparison of student performance in lower division collegiate general chemistry programs between selected community colleges and four-year institutions in Oregon

    Creator:
    Denney, Clifford Owen
    Abstract:
    This research was conducted to compare the performance of community college students to four -year institutional students both of which were enrolled in one of three different programs of general college chemistry for nonscience majors during the 1967 -68 academic year. The three programs were defined as follows: Program A...

  • Genetic and stability relationships of four Western Cascade soils

    Creator:
    Paeth, Robert Carl, 1925-
    Abstract:
    A sequence of soils derived from tuffaceous rocks was sampled on the H. J. Andrews Experimental Forest and adjacent U. S. Plywood land to determine some genetic and stability relationships. The less than two micron size fraction from each sample was characterized by x-ray diffraction with respect to crystalline clay...
