Estudio de la dosis recibida por los trabajadores de las instalaciones de un Acelerador Lineal de Electrones (LinAc) debido a la contribución de fotoneutrones y productos de activación
Abstract The main cause of mortality around the world is cancer, and it is expected that in the coming decades, cases of cancer in the population will be doubled. Despite this, it is possible to prevent, detect and treat many types of cancer using radiation as a treatment against this illness. Radia...

Despite this, it is possible to prevent, detect and treat many types of cancer using radiation as a treatment against this illness. Radiation therapy is one of the most widespread treatments applied to patients suffering from certain types of cancer. It employs ionizing radiation to damage or destroy cancer cells in the treatment area, and reduce or eliminate completely tumors. But, just as cancer cells are damaged, surrounding healthy tissues can also become damaged and produce unwanted effects to patients. Radiotherapy treatments are usually performed with linear accelerators, LinAc, which it allows to irradiate a tumor very accurately, avoiding the damage of surrounding healthy tissue. It uses beams of different energies, according to the energy established in the treatment planning. Usually, when these beams are high energies beams (> 10 MeV) photonuclear reactions are induced due to the interaction of photons with the LinAc head materials. These photonuclear reactions generate neutrons that are undesirable in the treatment, because they are an additional source of radiation and it means an additional radiological risk for the patients and workers. The work presented here, expects to quantify the amount of extra neutrons that have occurred in the medical linear accelerator Varian, due to these photonuclear reactions. To do this, we use the calculation program that is mainly used in the simulation of the transport of neutrons, photons and electrons: Monte Carlo N-Particle Code (MCNP).Universitat Politècnica de ValènciaJuste Vidal, Belen JeanneMiró Herrero, RafaelMorato Rafet, SergioDepartamento de Ingeniería Química y NuclearEscuela Técnica Superior de Ingeniería IndustrialInstituto Universitario de Seguridad Industrial, Radiofísica y MedioambientalRepositorio Institucional de la Universitat Politècnica de València Riunet20172017-10-0620172017-09-27master thesishttp://purl.org/coar/resource_type/c_bdccinfo:eu-repo/semantics/masterThesisapplication/pdfhttps://riunet.upv.es/handle/10251/88887reponame:RiuNet.
