The exposure needed for a clinically useful image requires much less precision when using digital radiography (DR) than when using screen/film (SF) radiography. The Automatic Exposure Control (AEC) device was developed for ensuring accurate and precise exposures with SF technology. This thesis evaluates the importance of the AEC device in...
The objective of this research was to estimate the radiological impact on various non-human biotas by the Fukushima Daiichi Nuclear power plant radiation release resulting from Japan's tsunami in March 2011 consistent with the recent recommendations of the International Commission on Radiological Protection. Soil concentration data given by Japan's Ministry...
Uranium is naturally radioactive and commonly found in water, soil, and rock. It can occur in elevated concentrations due to the presence of ore bearing bodies and be concentrated through human activities. This research focuses on uranium uptake for Capsicum annuum for three growing conditions. These include a set of...
Known as the fourth industrial revolution, digitization is an ongoing trend in all fields, in which various industries are integrating information technologies to support and improve their businesses. Nuclear technology industries have also increased their interest in data-driven methods by leveraging the potential of pattern recognition to identify anomalies and...
A unique tumor targeted method, which may be able to deliver a molecule to the surface of a tumor cell using the pH gradient between hypoxic tumor cells and normal tissue has recently been developed. Since solid tumors have been found to have a lower extra cellular pH compared to...
Students who believe that their intelligence is able to grow over time (malleable/ growth mindset) perform better on measures of academic success than students who believe that intelligence is a fixed trait that cannot be changed (fixed mindset; Dweck, 2000). Previous research on the effectiveness of mindset interventions have demonstrated...
College students need accurate information to both prevent sexual assault and to access services following sexual assault. Effective communication serves an important public health role by reducing both assaults and psychological distress. In contrast, ineffective communication can both increase assaults and psychological distress. Little empirical research is available to guide...
The U.S. Department of Energy (DOE) Order 458.1 states that the compliance with the DOE annual dose limit of 1 mSv (100 mrem) to a member of the public may be demonstrated by calculating dose to the maximally exposed individual (MEI) or to a representative person. Historically, the MEI concept...
The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) requires that Final Status Surveys be performed on materials and surfaces that vary in surface smoothness and/or uniformity. To obtain accurate survey data, it may be necessary to adjust detector response for these surface variations. NUREG-1507 refers to such surface efficiency...
As a standard practice, the use of radioactive materials has been widely used when treating many diseases. In recent years advances in biotechnology and labeling techniques have broadened the application of these materials. Candidates selected for radiopharmaceutical therapy may be treated on an outpatient basis or hospitalized following administration to...
