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...

Design and analysis of radiation shielding eyewear

Creator:: Spackman, David A.
Abstract:: The recent reductions to the international dose limit recommendations for the lens of the eye have renewed interest in radiation protection strategies in interventional fluoroscopy, where eye-lens radiation exposure occurs frequently. Radiationshielding eyewear can significantly reduce lens dose in these scenarios, but accurate protection factors are elusive because they depend...

Use of CR-39 for nuclear criticality accident dosimetry and high neutron dose monitoring

Creator:: Tai, Lydia I.
Abstract:: CR-39 foils were irradiated as part of nuclear accident dosimetry experiments using the Godiva reactor at the Nevada National Security Site and the Caliban and Prospero reactors at the Valduc Centre for Nuclear Studies in France. The irradiated foils were chemically etched using the standard Lawrence Livermore National Laboratory process...

Redefining Nuclear: Exploring Stigma, Climate Change, and the Adoption of Nuclear Power in Southeast Asia

Creator:: Chan, Allen M.
Abstract:: Nuclear energy is very efficient and cost-effective, but the stigma attached to it hinders its expansion around the world. However, with rising concerns over climate change and the fact that nuclear energy effectively has zero greenhouse gas emissions, there is an opportunity for nuclear to be more acceptable as a...

Human Eye Dosimetry: Air Gap Analysis by Shield Placement and Photon Energy

Creator:: Herrera, Joshua P.
Abstract:: When the ICRP updated their recommended limits for eye dose, they ignited a renewed interest in eye dosimetry. Especially, how the updated eye dose estimates affect current regulations and what that would mean to a radiation worker. Radiation workers are commonly required to wear leaded eyeglasses to reduce their dose...

A beta dosimeter and spectrometer utilizing plastic scintillators and a large-area avalanche photodiode

Creator:: Kriss, Aaron A.
Abstract:: The purpose of this research was to develop and test a radiation detector to perform beta dosimetry and spectroscopy. The detector utilizes plastic scintillator volumes to produce scintillation light in proportion to the amount of energy deposited in them, and a large-area avalanche photodiode to convert the light to electrical...

Development of a Fundamental Depth-Dependent Neutron Dosimetry Model

Creator:: Anspach, Logan J.
Abstract:: Current neutron dosimetry methods rely on the assumption that charged particle equilibrium (CPE) is established within the tissue medium. This maintains that the kinetic energy transferred to the medium (KERMA) is equivalent to absorbed dose. However, this assumption is only valid for large volumes such as the whole body. For...

Investigation into the effects of subsurface ice deposits on the shielding of fast spectrum nuclear reactors using Martian regolith

Creator:: Frey, Wesley D.
Abstract:: As human exploration of space continues, eventually sights will be set on establishing a permanent manned habitat on the surface of Mars. The success of such a base will depend on many new and developing technologies. Low mass and high energy density power production units will be of paramount importance....

Mapping dose rate of the Oregon State University neutron radiography facility

Creator:: Ropon, Kimberly
Abstract:: The Department of Nuclear Engineering at Oregon State University has recently introduced a neutron radiography facility (OSNRF). The facility is dependent on a neutron source established by the OSU TRIGA® Reactor (OSTR). It was unknown how accurately a computerized model of the OSTR in conjunction with the OSNRF could represent...
