  • Expanding alpha self-attenuation simulation by radioisotope dioxides

    The relative self-attenuation effect for different radionuclides were simulated to calculate the average yield and average energy thereof like the previous into AmO2 particulates. These include Americium-241, Neptunium-237, and Uranium-234, 235, and 238. Plutonium-240 was also an intended nuclide of interest but could not be simulated; attempts were met with a segmentation fault, and a…

  • Fine-tuning simulation of radioactive particulate self-attenuation

    Geant4 is a Monte Carlo simulation which requires a set of probable outcomes to process radiation events. These sets are called “physics lists” and are necessary to figure out what particles will do as time goes on. As it turned out, the necessary alpha particle physics list was not properly defined in the previous simulation…

  • Theoretical radiation exposure loss from radioactive particulate matter

    While exploring the properties of radioactive particulates in the context of exposure to resuspended radionuclides, I could not determine whether the size of a radioparticulate played a role in the delivery of ionizing radition. Alpha-emitters are especially problematic in the environment as the alpha radiation delivers more of an effective dose to tissue compared to…
