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...

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...

Hemicellulose utilization by yeast for ethanol production- adaptation, effect of inhibitors and a flux balance based analysis

Creator:: Avanasi Narasimhan, Ragothaman
Abstract:: A major challenge in ethanol production using lignocellulosic feed stock is inefficient utilization of hemicellulose, which accounts for 30-40% of lignocellulosic biomass. Xylose, comprising >60% of recoverable sugars from hemicellulose is a major product of the hemicellulose hydrolysis. Utilization of this carbon source would significantly increase the ethanol yield from...

The experience of alienation for males ages 16 - 19 from high school in the Pacific Northwest : A phenomenological inquiry

Creator:: Schulz, Lisa L.
Abstract:: This qualitative study examined the experiences and perceptions of males aged 16 – 19 who did not complete a traditional high school diploma program because of feeling alienated from the school system. Five participants described their school experiences from elementary school through the point in high school when they decided...

Stream channel stability and sensitivity to landscape history and land use changes in Kelley Creek, Portland, Oregon

Creator:: Murphy, Yarrow M.
Abstract:: This study examines stream channel erosion processes in a small urbanizing watershed influenced by deposits of the Columbia Basin catastrophic floods: Kelley Creek, a 12-km² tributary of Johnson Creek, located just east of Portland, Oregon. Information on landscape history, stream channels, and sediment dynamics was compiled. The effects of future...
