Abstract

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.

研究牙科应用中一些材料的辐射衰减和相互作用参数

对七种复合材料中的伽马射线、中子、电子和离子的相互作用进行了放射学理论研究。所研究的合金 A、合金 B、合金 C、焊料、锆、填料和丙烯酸树脂用于牙科，密度介于 1.104 和 15.522 g/cm3 之间。此外，还使用石英探测器测量了后三种复合材料对伽马射线（137Cs 和 60Co）（NaI(Tl) 探测器）、总伽马射线和快中子（252Cf 中子源）的影响。此外，还使用 Phy-X/PSD、MRCS 程序和基于蒙特卡罗的中子衰减特性 MATLAB 软件 (MCCNAP) 计算了 4.5 MeV 下的快中子去除截面 (FNRCS)。合金 A、B 和 C 的 FNRCS 和 MRC 值最大，平均值分别为 0.187 和 0.222 cm-1。Phy-X/PSD 和 Py-MLBUF 程序用于评估伽马射线在 0.015 - 15 MeV 宽能量范围内的相互作用参数。研究发现，对于所有形式的辐射，合金 A、合金 B 和合金 C 都是最佳的光子屏蔽复合材料。SRIM Monte Carlo 软件计算了 C4+、H+、He2+ 和 Au3+ 以及离子在宽能量范围（0.01-20 MeV）内的范围，ESTAR NIST 程序推导出了电子在宽能量范围（0.01-1000 MeV）内相互作用的总停止功率（TSP）和连续减速近似（CSDA）范围值。TPS和CSDA范围数据都表明，合金A、B和C比其他样品更受青睐，而且调查的离子范围随着样品密度的降低而增大，但在所有样品中，随着射弹能量的增加而增大。

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.
