Estudio computacional en Geant 4 de la interacción de protones con tejidos biológicos y con fluoruro de litio dopado con manganeso

Abstract

The thermoluminescence phenomenon is caused by the interaction between a doped chemical compound and incident radiation; said compound is ionized by changing its electronic configuration. After that, this material is heated to a certain temperature so that the electrons return to their initial configuration, emitting radiation in the form of photons. In particular, there is special interest in Lithium Fluoride as a thermoluminescent material, due to its possible uses and applications in various areas, such as dosimetry and medical physics, among others. In such a way, that studies for this type of crystals are required, in this work a computational simulation will be carried out in Geant4, in order to determine the dose received by Lithium Fluoride (LiF) doped with impurities of Manganese (Mn), when irradiated with Protons at certain energy ranges. A biological tissue (skin) will also be irradiated with protons in Geant4 and the corresponding dose will be determined. This in order to compare the doses obtained in both cases and thus be able to establish whether LiF is a material that resembles the response to radiation similar to that of soft tissue such as skin. In this work we want to carry out the respective computational simulations in Geant4, in order to establish comparisons between the inorganic and biological systems, ie, study the response of Lithium Fluoride (LiF) doped with Manganese (Mn) impurities and of the biological tissue (SKIN) when irradiated with protons.
