Dosimetria de radiação gama com espectroscopia de infravermelho por transformada de Fourier

Abstract

Gamma radiation is one of the most energetic radiations in the electromagnetic spectrum and has important applications in science and medicine. However, it also poses several risks due to the damage it can cause to living beings and is therefore classified as a form of ionizing radiation. The Fourier Transform Infrared (FTIR) spectroscopy technique is currently a fast and efficient technique for analyzing organic materials and can be used to identify and locate functional groups. In this study, a study of the dosimetry of gamma radiation in threonine, a proteinogenic amino acid that forms the genetic material of human beings and whose presence is necessary in the diet, was carried out using FTIR spectroscopy to identify the amine and carboxylic acid groups. By comparing with the literature, it is possible to identify breaks in interatomic bonds within the threonine molecule, using samples that received different radiation doses. This makes it possible to identify damage caused by ionizing radiation to a type of molecule, which may provide opportunities for future studies using other organic molecules and different types of ionizing radiation.
