Abstract

The average Relative Biological effectiveness (RBE) factors for neutron irradiation in the context of a BNCT treatment are studied. This research considers the various interactions and secondary particles of each process and estimates the RBE based on the damage induced in tissues by all of these particles. A novel concept of estimating the biological dose by means of weighted kerma factors is introduced. These weighted kerma factors include the RBE of each energy deposition based on an RBE-LET relationship for secondary charged particles and can be directly incorporated in weighted dose calculations from Monte Carlo simulations. Furthermore, the dependence of the neutron weighting factor on neutron energy for standard soft tissue is discussed.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
