99 Feasibility study of radioisotope production by simulating photoneutron reaction with MCNPX code Mohsen Nasiri mohsen nasiri@me iut ac ir September 20 2020 Department of Physics Isfahan University of Technology Isfahan 84156 83111 IranDegree Master of Science Language FarsiSupervisor Mohammad Hassan Alamatsaz Assoc Prof alamatsa@cc iut ac ir AbstractTechnetium 99m is the most widely used radioisotope in the world that it is being used for more than 80 of nuclear medicine procedures This radioisotope is produced directly from the cyclotron accelerator butits short half life of 6 hours makes it impossible to send it for longer distance areas A good substitution fortechnetium 99m is to use the molybdenum 99 radioisotope because it converts to technetium 99m with halflife of 66 hours allows it to be sent to longer distance areas Most of these radioisotopes are produced byreactors but it is also possible through accelerators including linear electron accelerators In this project withMCNPX code the simulation of 99 molybdenum production through linear electron accelerators of 10 and 18MeV was investigated Finally the optimum geometry of the photoneutron target was found and the activity ofmolybdenum 99 was obtained through a linear accelerator of 18 MeV in the amount of 469 mci at the end of48 hours KeywordsTechnetium 99m radioisotope molybdenum 99 linear electron accelerators MCNPX photoneutron activity
