Studying of radiation attenuation and interaction parameters of some materials used in dental applications
Gamma-ray, neutron, electrons and ions interactions in seven composites were theoretical radiological studied. Alloy A, alloy B, alloy C, solder, zirconium, filler, and acrylic are investigated which used in dentistry and have densities between 1.104 and 15.522 g/cm3. Additionally, an experimental investigation for the last three composites against gamma-ray (137Cs and 60Co) with NaI(Tl) detector, total gamma-ray and fast neutron using 252Cf neutron source were measured using by stilbene detector. Phy-X/PSD, MRCS program, and the Monte Carlo-based MATLAB software for Neutron Attenuation Properties (MCCNAP) were also used to calculate the fast neutron removal cross-section (FNRCS) at 4.5 MeV. Alloys A, B, and C had the greatest FNRCS and MRC values, respectively, averaged at 0.187 and 0.222 cm−1. Phy-X/PSD and Py-MLBUF programs were used to evaluate gamma radiation interaction parameters across a wide energy range from 0.015 − 15 MeV. For all forms of radiation studied, Alloy A, Alloy B, and Alloy C have been found to be the best photon shield composites. SRIM Monte Carlo software computed the range of C4+, H+, He2+ and Au3+, and ions across a wide energy range (0.01–20 MeV) of ions, and the ESTAR NIST program deduced the total stopping power (TSP) and continuous slowing down approximation (CSDA) range values for electron interactions across a wide energy range (0.01–1000 MeV) of electron. Both TPS and CSDA range data showed that Alloys A, B, and C were preferred over other samples, and the ranges of investigated ions increased with decreasing sample density but rose with projectile energies across all samples.
期刊介绍：
Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
