Título: | 33S as a cooperative capturer for BNCT |
Autor: | Praena, Javier CSIC; Sabaté-Gilarte, Marta; Porras, Ignacio; Esquinas, P. L.; Quesada, José Manuel; Mastinu, Pierfrancesco | Fecha de publicación: | 2014 | Editor: | Elsevier | Citación: | Applied Radiation and Isotopes 88: 203-205 (2014) | Resumen: | 33S is a stable isotope of sulfur for which the emission of an α-particle is the dominant exit channel for neutron-induced reactions. In this work the enhancement of both the absorbed and the equivalent biologically weighted dose in a BNCT treatment with 13.5keV neutrons, due to the presence of 33S, has been tested by means of Monte Carlo simulations. The kerma-fluence factors for the ICRU-4 tissue have been calculated using standard weighting factors. The simulations depend crucially on the scarce 33S(n,α)30Si cross-section data. The presence of a high resonance at 13.5keV was established by previous authors providing discrepant resonance parameters. No experimental data below 10keV are available. All of this has motivated a proposal of experiment at the n_TOF facility at CERN. A setup was designed and tested in 2011. Some results of the successful test will be shown. The experiment is scheduled for the period November to December 2012. © 2014 Elsevier Ltd. | URI: | http://hdl.handle.net/10261/123128 | DOI: | 10.1016/j.apradiso.2013.12.039 | Identificadores: | doi: 10.1016/j.apradiso.2013.12.039 issn: 0969-8043 e-issn: 1872-9800 |
