  • Monte Carlo derived absorbed fractions in a voxelized model of a rainbow trout

    Creator:
    Hess, Catherine A.
    Abstract:
    The International Commission on Radiological Protection (ICRP) has modeled twelve reference animals and plants (RAPs) with simple geometric shapes to be used when estimating radiation dose to non-human biota (NHB). In recent years, there has been interest in creating more realistic models in order to better understand the radiation interactions...

  • An investigation of chitosan for sorption of radionuclides

    Creator:
    Holfeltz, Vanessa Elaine
    Abstract:
    Chitosan is a biopolymer resulting from the deacetylation of chitin, the second most abundant biopolymer in nature. Chitosan has been successfully used in systems to remove metal ions and other pollutants from wastewater. Chitosan has shown promise as a sorbent for radionuclides in some aqueous waste streams. The sorption of...

  • Determining cross sections for potential medical radioisotopes

    Creator:
    Coleman, Joseph W.
    Abstract:
    Cost effective medical isotope production is key to the success of many forms of radiation therapy. A lymphoma clinical trial for copper-67 was canceled in 1997 due to insufficient production quantities of the isotope (Fast Flux Test Facility, 2001). To date high flux thermal reactors and particle accelerator facilities have...

  • Diffusion of selected radionuclides through Hanford Trench 8 soil material

    Creator:
    Schwab, Kristen E.
    Abstract:
    Shallow land burial in vadose zone sediment at the Hanford Site in Washington is being considered for the disposal of Category 3 low-level waste. A series of column experiments were conducted to evaluate and model the performance of the soil surrounding the trench encasement material for iodine-129 and technetium-99 by...

  • Medical radionuclides and their impurities in wastewater

    Creator:
    Hay, Tristan Ryan
    Abstract:
    NCRP report No.160 states that medical exposure increased to nearly half of the total radiation exposure of the U.S. population from all sources in 2006 (NCRP 2009). Part of this increase in exposure is due to the rise in nuclear medicine procedures. With this observed growth in medical radionuclide usage,...

  • Comparison of eye plaque dosimetry using deterministic and Monte Carlo methods

    Creator:
    Bristol, Jonathan R.
    Abstract:
    Eye plaque brachytherapy is an established technique for the treatment of ocular melanoma that allows for the preservation of the affected eye as well as visual function. A common treatment planning system for eye plaque procedures, Plaque Simulator (PS), assists physicists in calculating the radiation dose to the tumor and...
