Aproximación computacional de la interacción de la radiación gamma procedente de la captura de neutrones en biomoléculas a través de Geant4

Abstract

Neutron capture therapy for cancer with 157-Gd carrier (GdNCT) has become promising because of the type of nuclear reaction and the products that occur in this capture process, the products of the reaction are given by different types of phenomena with different ranges of energy; 158-Gd nucleus, gamma rays, internal conversion electrons, auger electrons, and x-rays. A computational study for the characterization of the reaction is performed with the help of the Geant4 tool and we compare the particles and their emitted energies with other computational studies, focusing on the gamma photons emitted in the simulation to estimate the energy and dose deposited in the brain tissue of NIST ICRP. The data obtained in this work are a contribution for the validation of the reaction of GdNCT in Geant4 and to the studies of GdNCT by the results of the energy and dose deposited by the gamma photons rarely studied in this type of therapy as possible agents causing damage to the tumor tissues.
