  • Retrospective thermal neutron fluence determination using lithium-ion mobile telephone batteries

    Creator:
    Dorrell, Nick J.
    Abstract:
    Fortuitous dosimeters are radiosensitive objects carried by an individual who was exposed to radiation. These objects can be analyzed some time after exposure and the results can be used to aid in calculating radiation fields and doses received by individuals. Items that make good fortuitous dosimeters are those that are...

  • 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...

  • Progress in the development of a portable phoswich-style skin contamination dosimeter

    Creator:
    Tang, Matthew M.
    Abstract:
    The Code of Federal Regulations (10CFR20.1201) mandates occupational dose limits to the shallow, lens and deep tissue layers. The NRC-accepted procedure of estimating dose to these layers from contamination events is laborious. The current work aims to further the development of a portable phoswich-style skin dosimeter that will operate in...

  • Radioxenon generation using highly enriched uranium

    Creator:
    Elliott, Anthony James
    Abstract:
    This work focuses on the generation and collection of four specific radioxenon isotopes; xenon-131m, xenon-133m, xenon-133 and xenon-135. These nuclides are created by fissioning a highly enriched uranium sample using a thermal neutron source from a university research reactor. The three main aspects of this work include: (1) Conducting preliminary...

  • Eye Lens Doses from Oblique Sources

    Creator:
    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...

  • 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...

  • The design, use and implementation of digital radiation detection and measurement equipment for the purpose of distance instruction

    Creator:
    Vasquez, David C.
    Abstract:
    Digital Instrumentation and Detection is becoming the future of radiation detection and measurement. Computers are able to perform digitally what before would have taken an extensive array of analog equipment. The art of teaching radiation detection and measurement is following this same pattern of a shift from purely analog to...

  • 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...

  • Low-Dose Ionizing Radiation Solid Cancer Risk in Adults : Radiation Hormesis Study Design

    Creator:
    Alhussan, Abdulaziz S.
    Abstract:
    Cancer risk at low-dose ionizing radiation has been the subject of great scientific controversy in the past century. The clear majority of national and international radiation protection regulators adopt the linear no-threshold (LNT) model based on the atomic-bomb survivors Life Span Study (LSS) for solid cancer risk assessment. The LNT...

  • Tissue weighting factors for radiation protection : derivation and parametric analysis

    Creator:
    Makinson, Kevin A.
    Abstract:
    Tissue weighting factors, w[subscript T], used to convert equivalent dose to effective dose, account for differences in radiosensitivity of various organs in the human body and allow users to compare individual organ detriment to whole body risk. They are explicitly calculated in ICRP 26, 60, and 103, although the methods...
