The effects of gamma radiation on Cascade hop

Creator:: Getty, Brooke
Abstract:: This gamma irradiation study was conducted to establish an LD50 of the hop (Humulus lupulus L.) cultivar Cascade . The overall, long term goal is to generate replacement hop cultivars by inducing minor but significant DNA alterations with gamma radiation to improve agronomic quality without changing the brewing profile. The...

Terahertz Induced Non-linear Electron Dynamics in Nanoantenna Coated Semiconductors at the Sub-picosecond Timescale

Creator:: Stickel, Andrew
Abstract:: This dissertation is an exploration of the material response to Terahertz (THz) radiation. Specifically we will explore the ultrafast electron dynamics in the nonperturbative regime in semiconductors that have been patterned with nanoantenna arrays using broadband, high intensity, THz radiation. Three main semiconductor materials will be studied in this work....

Microstructure of radiation damage in the uranium film and its backing materials irradiated with 136 MeV 136Xe+26, Microstructure of radiation damage in the uranium film and its backing materials irradiated with 136 MeV ¹³⁶Xe⁺²⁶

Creator:: Sadi, Supriyadi
Abstract:: Microstructure changes in uranium and uranium/metal alloys due to radiation damage are of great interest in nuclear science and engineering. Titanium has attracted attention because of its similarity to Zr. It has been proposed for use in the second generation of fusion reactors due to its resistance to radiation-induced swelling....

Dose response of zebrafish exposed to gamma radiation

Creator:: Haskins, Hillary Kate Marlane
Abstract:: Space radiation biology is an emerging field of research with a focus on improving the health and safety of astronauts in low-Earth orbit (LEO) and deep-space missions. Eye health is especially important to astronaut functionality. Recent studies have found an increased risk of cataract formation in astronauts with higher lens...

Creation and Application of Voxelized Dosimetric Models : An Evaluation of Dose Conversion Factor in Apis Mellifera

Creator:: Gomez Fernandez, Mario Enrique
Abstract:: Over the past decade the International Commission on Radiological Protection has developed a comprehensive approach to environmental protection that includes the use of Reference Animals and Plants (RAPs) to assess radiological impacts on the environment. For the purposes of calculating radiation dose, the RAPs are approximated as simple shapes that...

A quantitative comparison of cardiovascular imaging systems with respect to the resolution capabilities and the resulting skin entrance doses operating in both fluoroscopic and cine mode

Creator:: Helms, W. Scott
Abstract:: The increasing use of medical procedures using ionizing radiation has increased significantly in recent years. In 1987, the National Council on Radiation Protection Report 93 (NCRP) reported that the average exposure ionizing radiation was 53mRem/year (0.53mSv/year). In their most recent study on radiation exposures NCRP Report 160 in 2009, the...

Blood-based gene expression as a biodosimetry model for neuroblastoma patients treated with ¹³¹I-mIBG

Creator:: Edmondson, David A.
Abstract:: Internal dosimetry is challenging and relies on estimates using MIRD or ICRP biokinetic models. To address this, we looked at gene expression analysis in whole blood from radiotherapy patients. Patients with relapsed or refractory neuroblastoma who received ¹³¹I-mIBG at UCSF were used to correlate internal ionizing radiation (IR) dose with...

Beta-particle backscatter factors and energy-absorption scaling factors for use with dose-point kernels

Creator:: Mangini, Colby D.
Abstract:: 'Hot particle' skin dosimetry calculations are commonly performed using homogeneous dose-point kernels (DPK) in conjunction with scaling and backscatter models to account for non-homogeneous geometries. A new scaling model for determining the actual DPK for beta-particles transmitted by a high-Z source material has been developed. The model is based on...

Improvements in the dosimetric models of selected benthic organisms

Creator:: Caffrey, Emily Amanda
Abstract:: The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...

Measurement and analysis of soft error vulnerability of low-voltage logic and memory circuits

Creator:: Pawlowski, Robert
Abstract:: Scaling the supply voltage into the sub/near-threshold domain is one of the most effective methods for improving the energy efficiency of next-generation electronic microsystems. Unfortunately, the relationship between low-voltage operation and radiation-induced soft error rate is not widely known, as little research has been previously performed and reported for soft-error...
