Abstract or Summary
  • Medical Isotopes are a necessity in modern medicine for cancer treatments and medical imaging. In order to ensure that the needs and demands are met for the medical procedures, facilities are put in place to produce these isotopes. There are over 25 different isotopes of interest being produced by more than 35 research reactors across the United States. A key component in medical isotope production is the isotope separation process. During this process, several types of radioactive gases are released that would otherwise not leave the nuclear fuel component. One of these radioactive gases is radioxenon. The release of radioxenon into the environment is of concern to the Comprehensive Test Ban Treaty Organization (CTBTO) as one of the key critical sampling techniques utilized to detect a nuclear detonation is the presence of radioxenon. As more facilities release radioxenon, background levels increase, desensitizing the equipment, and making it more difficult to detect. For this purpose, the detection of a medical isotope facility through the use of radioxenon is an interest to the CTBTO as an attempt to reduce the background levels of radioxenon and ensure that the detonation capabilities remain unaffected. This thesis will investigate the capabilities of detecting these medical isotope facilities through the use of radioxenon detection. Additionally, probabilities of detection will be determined in order to accurately identify these facilities.
