Use of GIS software to map contaminant distributions and determine integrated dose for purposes of assessing impact to biota

Creator:: Myers, Margaret C.
Abstract:: 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...

Examination of uranium uptake by root vegetables and consequences for human consumption

Creator:: AlZahrani, Abdullah Bakheet
Abstract:: Uranium is the most common radionuclide that found in the nature. It is a radionuclide with a very low specific activity. There is limited data on plan uptake of uranium. This research was to determine the plant uptake of uranium, calculate the concentration ratio, and estimate the dose from eating...

Development of a binary mixture gas composition instrument for use in a confined high temperature environment

Creator:: Cadell, Seth R.
Abstract:: With recent advancements in material science, industrial operations are being conducted at higher and higher temperatures. This is apparent in the nuclear industry where a division of the field is working to develop the High Temperature Gas Reactor and the Very High Temperature Gas Reactor concurrently. Both of these facilities...

Study on Depressurized Loss of Coolant Accident and its Mitigation Method Framework at Very High Temperature Gas Cooled Reactor

Creator:: Gutowska, Izabela
Abstract:: To understand how a Depressurized Loss of Forced Convection (D-LOFC) initiated from a double-ended guillotine break may affect further operation of a High Temperature Gas Cooled Rector (HTGR), thorough understanding of each specific stage of this event is required. Key considerations that need to be determined is the amount of...

Development of a Novel MEMS Thermal Sensor Array for Pebble Bed HTGRs

Creator:: Hertel, Matthew A.
Abstract:: A novel high temperature thermal instrument is proposed, which utilizes a dual-sensing platinum resistor encased in a mono-crystalline alpha-alumina (sapphire) substrate. The instrument is comprised of four platinum trace elements, oriented with 90° rotational symmetry atop a 1120 oriented crystal lattice substrate. All four of these sensors measure temperature directly...

Geoarchaeological research within five river miles of the Upper Klamath River Canyon : use of pedogenic properties to calculate alluvial terrace age

Creator:: Hescock, Sara
Abstract:: Soil is a valuable medium when investigating the past-- from understanding rates of development, landform evolution, to the construction of various predictive models. Landforms and sediments provide insight into depositional environments and soil morphology indicates pedogenic change within those landforms. The rate at which pedogenesis occurs has been quantitatively measured...

Paleoenvironmental Reconstruction of Late Pleistocene and Holocene Human Ecologies: A Case Study of Phytoliths from the Lower Salmon River Canyon, Idaho

Creator:: Knapp, Dante L.
Abstract:: Archaeological excavations of the Cooper's Ferry site in the Lower Salmon River Canyon, Idaho, have revealed a stratified record of cultural occupation, spanning the late Pleistocene and early Holocene periods. The purpose of this study was to contribute to the understanding of cultural adaptive strategies represented in the archaeological record...

A provenance study of crypto-crystalline silicates at the Cooper's Ferry site : a geochemical approach

Creator:: Nyers, Alexander John
Abstract:: A provenance study of crypto-crystalline silicates was performed at the Cooper's Ferry archaeological site in west-central Idaho on the Columbia Plateau. In this research, the author used instrumental neutron activation analysis as well as portable x-ray fluorescence to examine and characterize the geochemistry of 300 geologic samples of crypto-crystalline silicates...

Revisiting Lōʻihi: Geochemistry of Kamaʻehuakanaloa Lavas Reveals Complexities in the Pre-Shield to Shield Transition and Hawaiian Mantle Plume Source

Creator:: Truong, Thi B.
Abstract:: Studies of Hawaiian volcanoes contribute valuable insights about Earth processes and mantle evolution, and are fundamental for understanding the construction of the largest volcanoes on terrestrial planets. The pre-shield stage exists in every Hawaiian volcano, but is usually blanketed by high volume tholeiitic lava flows during the main shield stage....

A Deterministic Photon and Electron Dosimetry Model for the Lens of the Eye

Creator:: Boozer, David L.
Abstract:: The lens dose equivalent (LDE) is a regulatory limit set to protect radiation workers. Current methods for estimating the LDE are specific to beam sources in a vacuum and require interpolating data from tables. A new set of deterministic equations for photon and electron point sources has been developed. These...
