Effects of Radiation Exposure on Lung Carcinogenesis
… Analysis of several human populations exposed to radiation reveals that the lung is remarkably susceptible to the carcinogenic effects of radiation exposure. The considerable lung surface area and slow rate of epithelial turnover may have causal roles in this vulnerability. This may be due to the …

Measuring terrestrial wildlife external radiation exposure under field conditions
… to develop methods for measuring external radiation exposure of free-ranging terrestrial animals under field conditions. An evaluation of available passive dosimeter technologies was undertaken and guidance developed on the selection of dosimeters for different sizes of terrestrial animals. …

Investigating the Effects of Particle Radiation Exposure on Lung Carcinogenesis
… both men and women. The overall increase in radiation risk for human cancer types has been substantiated by the epidemiological data obtained from atomic bomb survivors and uranium mine workers. The lung has a large surface area which makes it a prominent target for radiation exposure making …

Late Effects of Hypothalamic Radiation Exposure in Pediatric Brain Tumor Survivors
… brain tumor survivors treated with hypothalamic radiation are at increased risk for developing components of metabolic syndrome, characterized by central obesity and two of the following: elevated triglycerides, low HDL, elevated blood pressure, or fasting hyperglycemia. These patients may also …

RF-EMF Radiation Exposure and Radio Resources Management in 5G Wireless Network
… and radiofrequency electromagnetic field (RFEMF) radiation exposure (a health challenge on user) emitted in both the uplink and downlink of wireless networks, especially the 5G mobile network. Therefore, this research aims to assess the impacts of these challenges, develop and evaluate efficient …

Examination of molecular genetic factors involved in sensitivity to breast cancer following radiation exposure
… systems can result in radiosensitivity. Because radiation exposure, DNA repair deficiency and telomere malfunction are associated with cancer risk, we investigated Lymphoblastoid Cell Lines (LCLs) from breast cancer patients and controls for chromosomal radiosensitivity, relative telomere length, …

Pharmacological countermeasures for the prevention and treatment of toxic radiation exposure in space flight
Ionizing radiation toxicity in space poses a significant occupational risk to astronauts and is an area of critical concern for space traveling agencies. However, despite technological advances in other areas, a viable solution to this problem has not been developed. The focus of this capstone is …

Effect of sun radiation exposure on indoor air quality of car interior in tropical country
… certain minutes or hours of parking due sun radiation exposure, forced car user to wait for a period of time to cool down the car interior temperature. Increase of car interior temperature caused heat stroke to living creature and degradation of material and finishes. The objective of this …

Radiation exposure liability : the burden of responsibility and compensation in civilian and military nuclear ventures
… Nevada Test Site, allow for the examination of radiation injury liability in the context of existing radiation compensation systems. The Price-Anderson Nuclear Industries Indemnity Act, which governs civilian nuclear use, and the Radiation Exposure Compensation Act, which governs compensation …

FUNCTIONAL, STRUCTURAL, CELLULAR, AND MOLECULAR CARDIAC RESPONSES IN NONHUMAN PRIMATE MODELS OF MENOPAUSE AND RADIATION EXPOSURE
… estrogen loss (menopause) and ionizing radiation exposure are gaining attention as drivers of cardiac remodeling leading to heart failure, particularly heart failure with preserved ejection fraction (HFpEF). Myocardial fibrosis appears to be a shared pathologic feature of both …

Facility-Specific Radiation Exposure Risks and Their Implications for Radiation Workers at Department of Energy Laboratories
… for evaluating the occupational risks of exposure to hazardous substances in any setting where As Low As Reasonably Achievable (ALARA) practices are mandated or used. The evaluation is performed by developing a hypothesis-test-based procedure for evaluating the homogeneity of various …

Radiation exposure of human populations in villages in Russia and Belarus affected by fallout from the Chernobyl reactor
… affected people. In this thesis, the current day exposure to inhabitants living in some of the villages in the Bryansk region (Russia) have been assessed using similar methods of individual monitoring as during earlier phases of the project (1991-2000). This included personal TLDs and individual …

A computer model for investigating the biomechanical effects of radiation exposure on pathological and non-pathological living human cells
The cellular response to radiation insult and studies have been carried out to investigate aspects of the cytoskeleton and the force response of the cell when probed by an AFM. Confirmed for the first time that there was a statistically significant difference for the PNT2 and PC3 cell lines in …

Effects of combined exposure to ethanol and ionizing radiation on the antioxidant status of in vitro and in vivo models
"Ethanol and ionizing radiation exposure are independently known to cause tissue damage through various mechanisms. Non-enzymatic and enzymatic metabolism of ethanol, the latter via the cytochrome P₄₅₀2E1-dependent pathway, produces free radicals which deplete cellular glutathione (GSH). Ionizing …

Histopathological and Molecular Changes in Intestinal Tissue Following Proton Exposure in Varying Mouse Models
Most people are aware that radiation can have negative health consequences for human beings exposed to the phenomena. These negative outcomes are dependent upon dose, dose rate, the individual’s genetic makeup and other factors. Many people do not know, however, that radiation is present constantly …

Essays in applied microeconomics: effects of environmental and trade policy shocks
Chapter 1 studies the long-run effects of radiation exposure from U.S. atmospheric nuclear weapon tests on mortality. Using individual-level vital records and a differences-in-differences approach, I analyze county-level radiation fallout data from tests conducted at the Nevada Test Site between …
