Speaker
Description
During the testing phase of the Xenon International radioxenon monitoring system in Knoxville, Tennessee, USA, there were observations of non-traditional xenon isotopes: Xenon-125, Xenon-127, Xenon-129m, and Xenon-122 (via the decay of Iodine-122). While the production mechanisms for non-traditional isotopes were hypothesized, it would be beneficial to perform a complete study on the production scenarios for the non-traditional xenon isotopes compared to the standard radioxenon isotopes of Xenon-135, Xenon-133, Xenon-133m, and Xenon-131m. One production mechanism that is of particular interest following the observations of Xenon International is a spallation neutron source. While there are several spallation neutron sources around the world, the production of non-traditional radioxenon isotopes depends on parameters like the target material, beam energies and gas abatement. We have investigated the production mechanisms of the non-traditional isotopes and developed a model for predicting the amount of non-traditional xenon isotopes compared to traditional xenon isotopes that are produced through methods like neutron spallation.
Promotional text
Understanding the radioxenon signals that may come from background sources of radioxenon allows for a better identification of potential interferences that may be seen in the future.
