  • 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...

  • Commissioning of ADAC Pinnacle for IMRT utilizing solid compensators

    Creator:
    Brumley, Willis E.
    Abstract:
    Use of solid compensators is a very effective means of implementing IMRT on any linear accelerator. The standard practice has been IMRT delivery using accelerators equipped with multi-leaf collimators (MLC’s). Truth is the addition of MLC’s to an accelerator is quite expensive. Previous studies have shown solid compensators to have...

  • Dose to the female breast from nuclear medicine and diagnostic radiology

    Creator:
    Patel, Aarti
    Abstract:
    There has been increased concern about radiation dose to the female breasts, with approximately 200,000 new breast cancers being diagnosed each year in the United States. The unprecedented increase in the use of radiologic exams on younger women has also raised some additional concerns about how procedures are performed. The...

  • An allometric examination of the relationship between radiosensitivity and mass

    Creator:
    Bytwerk, David Paul
    Abstract:
    The results of a review of six decades of existing literature for 50% lethal dose data across a range of phyla are presented. The collected 50% lethal dose data is limited to adult organisms subjected to acute doses of gamma radiation. The data collected is examined to determine whether useful...

  • 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...
