  • Comparison of dosimetric modeling of the International Commission on Radiological Protection trout reference animal

    Creator:
    Comolli, Michelle LeAnne
    Abstract:
    Radiation protection has historically been from a human protection approach, therefore many studies have neglected the potential dose contribution from the gastrointestinal tract (GIT) in animal studies. The International Commission on Radiological Protection (ICRP) utilized simplified geometric shapes with Dose Conversion Factors (DCF) based on homogenized models for the trout...

  • Design, construction, and analysis of a skin contamination dosimeter

    Creator:
    Cazalas, Edward J.
    Abstract:
    International recommendations provided by the International Commission on Radiation Protection (ICRP), as well as national regulations, set by the U.S. Nuclear Regulatory Commission (NRC), state that the exposure of skin to highly concentrated radioactive sources should be monitored at specified depths in skin and kept below specific dose equivalence levels....

  • Displacement-based fluorescent microRNA biosensors : design principles and analytical metrics

    Creator:
    Larkey, Nicholas E.
    Abstract:
    One post-transcriptional mechanism that regulates the progression of cancer and other diseases involves small 22-23 nucleotide sequences called microRNA (miR). Early detection of small changes in concentration of these biomarkers holds potential to diagnose diseases at their earliest stages. Use of current nucleic-acid based biosensors, like molecular beacons, for in...

  • Modeling of an Urban Radiocesium Pathway from Catchment to Wastewater Treatment Sludge

    Creator:
    Ng, George M. H.
    Abstract:
    The urban hydrology and hydraulics program, US EPA SWMM 5, has been coupled with a compartment model of a wastewater treatment plant (WWTP) in the system dynamics software, STELLA, to simulate the radiocesium pathway from urban catchment to the wastewater treatment sludge. Two literature case studies were re-examined. Firstly, a...

  • The Association Between Extreme Climate and Diarrheal Illness in North America

    Creator:
    Lyon-Colbert, Amber
    Abstract:
    The etiology and transmission of bacterial diarrheal pathogens is complex, making evaluating the association between extreme climate and diarrheal illnesses in North America challenging. Changes in climate may impact the survival, reproduction, and distribution of pathogens that cause diarrheal illness. Evidence supports the hypothesis that reproduction, survival, and transmission ability...

  • 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...

  • Characterization of the onset of charged particle equilibrium for photon dose to skin

    Creator:
    Ryan, Michael C.
    Abstract:
    In the U.S., the Nuclear Regulatory Commission (NRC) is responsible for setting annual dose limits. For cases of hot particle contamination these limits are set at depths in skin of 7 mg/cm², 300 mg/cm², and 1000 mg/cm². However, at such shallow depths, the lack of charged particle equilibrium (CPE) precludes...

  • Pine Tree Dosimetry: Development of Geometric and Compositionally Specific Sectional Models for Organ Dose Assessment

    Creator:
    Condon, Caitlin A.
    Abstract:
    Ideally, dosimetric models for pine trees will accurately reflect the doses to its critical organs. However, existing models (e.g. that in ICRP 108) for the pine tree are over simplified or solely focused on estimating doses to one specific organ, and none of the existing models attempt dosimetry to the...

    Trakowski, Ian M.
    Abstract:
    Since the International Commission on Radiation Protection (ICRP) recommended a revision to the eye lens dose limits in ICRP Publication 118 (Stewart, 2012) the radiation protection community has conducted many new studies related to eye dosimetry. The recommended reduction of eye lens dose limits may result in the reduction of...

  • Structural Insights into Novel Sugar Phosphate Cyclases and Flavoenzymes

    Creator:
    Kean, Kelsey M.
    Abstract:
    The function of a protein is defined by its three-dimensional structure, and in understanding the three-dimensional structure of a protein, we gain an understanding of its function and mechanism. Protein structures, especially at high resolution, can provide detailed insights into many elements of enzyme function and catalysis – identifying residues...
