  • Dosimetric Evaluation of Nasal Cavity Basal Cell Layer during Radiotracer Administration

    Creator:
    Flora, Rigel
    Abstract:
    New delivery methods for radiotracers are constantly being proposed. Two key properties of the delivery method must be analyzed: dose to patient and effectiveness of delivery. In this work, the localized skin dose for intranasal administration of 18F was determined utilizing MCNP code. An anatomically accurate nasal cavity was constructed...

  • 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...

  • 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...

  • Locating and Quantifying Contamination Deposited in Radiation Puncture Wounds

    Creator:
    Wehmann, Nicholas K.
    Abstract:
    Internal dosimetry models show a representation of how radionuclides move through the body. This study takes a look at radiation wounds by modelling a puncture wound to the hand using Microshield software. An analysis of these models provides a triangulation method that could be used to investigate wound characteristics, as...

  • Utilization for a triple-layer phoswich detector for beta spectral stripping

    Creator:
    Alkhudhiri, Bandar
    Abstract:
    To quantify the relative activity contributions of beta emitters in mixed emission source spectra, the triple-layer phoswich detector was modeled to generate beta energy absorption spectra from mixed beta sources. These mixed sources include four pure beta emitters (C-14, Tc-99, Sr-90, and Y-90). Monte Carlo N-Particle (MCNP) computer code was...
