The elemental composition and surface morphologies of the (Li2B4O7) (100-x) - (Hematite) x glass samples (here x = 10,20, 30 and 40% weight) were acquired by SEM/EDX measurements. Using the EDX results, the mass attenuation coefficient (µ/ρ in units of cm2/g) of the glasses were generated with MCNPX simulation codes and calculated by XCOM software. Both results were matched by utilizing relative deviations. Next, Half Value Layer (HVL), Effective Atomic Number (Zeff), Mean Free Path (MFP), Exposure Buildup Factors (EBF), Energy Absorption Buildup Factors (EABF), Fast Neutron Removal Cross Sections (ΣR) and Relative Dose Distribution (RDD - for gamma and neutron) were calculated. Mass Stopping Power (MSP) and Projected Range (PR) values were calculated to examine the proton and alpha shielding properties of the hematite doped glass samples. According to the results obtained, µ/ρ, Zeff, and ΣR values increase as the percentage of hematite mineral in the glass samples increases. In addition, it was observed that HVL, MFP, EBF, EABF and RDD values decreased with increasing hematite percentage. The increase in the rate of hematite in the glass provided alpha and proton particles to have shorter ranges. Among the studied glass samples, lithium borate glass with 40% hematite mineral ratio is the sample with the best gamma, neutron and charged particles shielding features.

氧化铁(III)掺杂的硼酸锂玻璃:结构和带电粒子/光子屏蔽特性

(Li 2 B 4 O 7)(100-x)-(赤铁矿)x玻璃样品(此处x = 10,20、30和40%重量)的元素组成和表面形态是通过SEM / EDX测量获得的。使用EDX结果,通过MCNPX模拟代码生成玻璃的质量衰减系数(μ/ρ,以cm 2 / g为单位),并通过XCOM软件进行计算。通过利用相对偏差来匹配两个结果。接下来,半值层(HVL),有效原子序数(Z EFF),平均自由程(MFP),曝光积聚的因素(EBF),能量吸收累积因子(EABF),快中子去除截面(Σ [R)和相对剂量分布(RDD-γ和中子)。计算了质量阻止能力(MSP)和投影范围(PR)值,以检查掺杂赤铁矿的玻璃样品的质子和α屏蔽性能。根据获得的结果,μ/ρ,Z EFF,Σ [R值增加,因为赤铁矿矿物中的玻璃样品的百分比增加。另外,观察到,随着赤铁矿百分比的增加,HVL,MFP,EBF,EABF和RDD值降低。玻璃中赤铁矿比率的增加使α和质子颗粒具有更短的范围。在所研究的玻璃样品中,具有40%赤铁矿矿物比的硼酸锂玻璃是具有最佳γ,中子和带电粒子屏蔽性能的样品。
