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...

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...

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...

Forested plant associations of the Colville National Forest

Creator:: Williams, Clinton K., Kelley, Brian F., Smith, Bradley G., and Lillybridge, Terry R.
Abstract:: A classification of forest vegetation is presented for the Colville National Forest in northeastern Washington State. It is based on potential vegetation with the plant association as the basic unit. The classification is based on a sample of approximately 229 intensive plots and 282 reconnaisance plots distributed across the forest...
