Abstract

Boron Neutron Capture Therapy (BNCT) is a promising form of radiotherapy expected to be effective in treating refractory cancers such as glioblastoma. A key factor in BNCT is the neutron energy spectrum in the epithermal range (0.5 eV–10 keV), which is challenging to evaluate due to its broad and low-energy characteristics. This study proposes a novel measurement method for the neutron energy spectrum in the epithermal range, utilizing a combination of activation foils and a position-sensitive proportional counter to capture the full energy range of neutrons in BNCT. A prototype of the spectrometer was developed, and numerical validation was performed. The results of the numerical study demonstrated that the proposed spectrometer can accurately evaluate the neutron energy spectrum across a broader energy range compared to existing methods.

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.
