  • A study of state and federal radioisotope licensing requirements

    Creator:
    Hess, David Owen
    Abstract:
    At the time of this study 19 states have entered into agreements, one state agreement is pending and one state has submitted its proposal for entering into an agreement with the Atomic Energy Commission for the purpose of assuming regulatory authority over (1) byproduct, (2) source and (3) special nuclear...

  • 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...

  • Argon-41 production by the OSU TRIGA III reactor

    Creator:
    Meck, Robert Allen
    Abstract:
    A sensitive ion chamber-electrometer system was used to determine the Oregon State University TRIGA III reactor's ⁴¹Ar production rate as a function of steady state reactor power and production of ⁴¹Ar due to reactivity pulses up to $3.00. The relative contributions of the argon duct effluent and the pneumatic transfer...

  • Monte Carlo uncertainty reliability and isotope production calculations for a fast reactor

    Creator:
    Miles, Todd L.
    Abstract:
    With the advent of more powerful, less expensive computing resources, more and more attention is being given to Monte Carlo techniques in design application. In many circles, stochastic solutions are considered the next best thing to experimental data. Statistical uncertainties in Monte Carlo calculations are typically determined by the first...

  • A web-based medical radionuclide database

    Creator:
    Jue, Tracy M.
    Abstract:
    Currently the Food and Drug Administration publishes radiopharmaceutical information for physicians to choose appropriate medical diagnosis and therapy for their patients. The primary functions of these radiopharmaceuticals are diagnosis and delivering doses to a patient with appropriate energy, biological half life, chemical behavior, and radiological half life. These radiopharmaceuticals preferentially...

  • Testing Continuity between Versions 5.3.9 and 6.3.1 of Plaque Simulator for Planning Eye Plaque Brachytherapy Cases

    Creator:
    Polsdofer, Elizabeth M.
    Abstract:
    The purpose of this study is to examine the challenges of accepting and commissioning a new treatment planning system for eye plaque brachytherapy. Currently Oregon Health and Science University (OHSU) utilizes v5.3.9 of the Plaque Simulator software to plan all of its eye plaque brachytherapy cases. However, v5.3.9 is no...

  • 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...

  • Predicting dose and cell survival distributions for brachytherapy sources

    Creator:
    Stringham, Michael J.
    Abstract:
    The focus of this thesis is to determine the biological impact of dose from brachytherapy sources commonly used in cancer treatment. To achieve this goal, the Monte Carlo code PENELOPE was used to simulate point sources of four different isotopes (¹⁰³Pd, ¹²⁵I, ¹³⁷Cs, and ⁹⁰Sr) in an infinite medium of...

  • 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...

  • An investigation of radioactively contaminated wastewater reclamation plant biosolids

    Creator:
    Brannan, C. Thomas
    Abstract:
    Within the last 15 years, wastewater treatment plants have increasingly begun to find radioactive isotopes incorporated in biosolids. Regulations concerning the disposal of radioactive material via sanitary sewer systems were in place since the early 1960's and recently were further restricted. However, the updated regulations would not have prevented certain...
