  • Measurement of gastro-intestinal and gonadal exposures in routine upper gastro-intestinal examinations using a conventional and an image intensifier fluoroscope

    Creator:
    Envall, Kenneth Roy
    Abstract:
    This study modified certain existing techniques used in the determination of the radiation exposure to various anatomical structures of the gastro-intestinal tract during fluoroscopic examinations. Monitoring films were attached directly to the patient during the routine upper gastro-intestinal examination, instead of placing the films on the panel of the fluoroscope....

  • Absorbed dose from X rays in soft tissue adjacent to bone measured by induced conductivity in polyethylene films

    Creator:
    Lentsch, Jack Wayne
    Abstract:
    The X-ray dose absorbed in soft tissue located near plane bone interfaces and in parallel-slab bone cavities was measured experimentally with a polyethylene-film dosimeter. The dose absorbed in soft tissue adjacent to plane bone interfaces was measured by placing a 12.7 micron film of polyethylene, upon which were deposited graphite...

  • Enlarging radiation survey read-outs for large audience viewing

    Creator:
    Aaserude, Robert Arnold
    Abstract:
    A method is presented for enlarging read-outs from a Victoreen Model 575 Radocon, an ionization chamber type of radiation survey instrument. The read-out enlargement is accomplished by taking the signal across the Radocon indicating meter, amplifying it, and using the amplified signal to drive a projection meter. The face and...

  • Measurement of peak kilovoltage across x-ray tubes by ionization methods

    Creator:
    Burnett, Bruce Merl
    Abstract:
    Voltage calibration methods used with X-ray tubes are either electrical procedures requiring direct electrical connection or ionization techniques which require no electrical connection to the generating system. One major restriction on the use of electrical methods for measuring the voltage applied to X-ray tubes is that special electrical adaptors are...

  • Design and construction of an X-ray machine for lecture demonstration

    Creator:
    Semler, Mark Orion
    Abstract:
    A design for an x-ray machine to be used as a visual aid for the instruction of x-ray theory and x-ray machine operation has been presented. From this design an x-ray machine was constructed and tested. Components used in an x-ray machine have been divided in to three sections; a...

  • Design and construction of an X-ray diffraction teaching device

    Creator:
    Elle, Donald Robert
    Abstract:
    A design for an x-ray diffraction teaching device has been presented. From the design a diffraction device has been constructed. Based on the principles of the original work by Max von Laue, a diffraction camera has been constructed using a diagnostic x-ray machine. The diffraction camera provides a fast, safe,...

  • A study of the deterioration of X-ray fluoroscopic screens

    Creator:
    Properzio, William Stuart, 1940-
    Abstract:
    From the time when fluoroscopic screens were first used there have been scattered references to reduction in their light output due to age, use, etc. References are scarce and usually devoid of quantitative data. A long-range program has been set up in an effort to arrive at some meaningful information....

    Creator:
    Hess, David Owen
    Abstract:
    At the time of this study 19 states have entered into agreements, one state agreement is pending and one state has submitted its proposal for entering into an agreement with the Atomic Energy Commission for the purpose of assuming regulatory authority over (1) byproduct, (2) source and (3) special nuclear...

  • A study of relative speeds of medical x-ray film and intensifying screen combinations

    Creator:
    Gross, Richard Eugene
    Abstract:
    The objective of this study was to determine the relative speeds of available medical x-ray films exposed directly to x-rays and exposed in combination with various types of intensifying screens. The information obtained from this sensitometric data was used to obtain factors by which a radiographic exposure technique with one...

  • Measurement of environmental gamma exposure by thermoluminescence dosimetry

    Creator:
    Fitzsimmons, Charles Ke
    Abstract:
    Energy dependence, angular dependence, and linearity of response to exposure levels were studied for the thermoluminescent dosimeter used in an environmental monitoring network. The dosimeter consisted of a manganese activated calcium fluoride phosphor (Ca F₂: Mn) bonded to a helical heating element and encapsulated in a gas filled glass tube....
