Rocks are comparatively high-density materials, which can be developed as a protecting wall to reduce the radiation contact at buildings where gamma radiation is utilized. The Visible Near Infrared (VNIR) and Shortwave near Infrared (SWIR) bands of Landsat 8 remote sensing data are utilized to discriminate the mafic and ultramafic rocks’ lithology. The different Band combinations, band ratioed composites, Principal Component Analysis (PCA), and Minimum Noise fraction (MNF) have been done and interpreted. The PCA 415, MNF 253, and bandratios 3/6, 7/4, 5/2 have been used to discriminate the mafic-ultramafic complexes in a good manner. The significant oxides values were retrieved through the X-Ray Fluorescence (XRF) method, and density is calculated. In order to assess the three investigated rocks' radiation shielding features, the linear attenuation coefficient (LAC) and mass attenuation coefficient (μ/ρ) were simulated using Monte Carlo simulation. Simultaneously, the μ/ρ and the effective atomic number (Z_eff) were estimated using Phy-X software between 0.015 and 15 MeV. The results revealed that the μ/ρ and Z_eff follow the order of Gabbro > Peridotite > Pyroxenite. At low energies, the maximum μ/ρ is reported for all investigated rocks. A steep decrease in μ/ρ values is found, which demonstrates that the rocks have much better attenuation at low energies while being the least effective at high energies. The μ/ρ of Peridotite decreases from 11.540 cm²/g at 0.015 MeV to 5.122 cm²/g at 0.02 MeV, 1.681 at 0.03 cm²/g MeV, and 0.814 cm²/g at 0.04 MeV. At 0.015 MeV, Peridotite has a Z_eff of 17.34, Pyroxenite has a Z_eff of 17.27, and Gabbro has a Z_eff of 18.12. The half-value layer (HVL) for Peridotite decreases from 0.02 cm at 0.015 MeV, to 0.31 cm at 0.04 MeV, 1.95 cm at 0.20 MeV, 3.94 cm at 1.00 MeV, and 11.28 cm at 15.00 MeV. At all energies, however, Gabbro has the least HVL, followed by Pyroxenite and Peridotite.

岩石是密度相对较高的材料，可以将其开发为保护墙，以减少使用伽马辐射的建筑物的辐射接触。Landsat 8 遥感数据的可见近红外 (VNIR) 和短波近红外 (SWIR) 波段用于区分基性和超基性岩石的岩性。已经完成并解释了不同的波段组合、波段比率复合材料、主成分分析 (PCA) 和最小噪声分数 (MNF)。PCA 415、MNF 253 和bandratios 3/6、7/4、5/2 已被很好地用于区分镁铁质-超镁铁质配合物。通过 X 射线荧光 (XRF) 方法检索重要的氧化物值，并计算密度。为了评估三个被调查岩石的辐射屏蔽特性，使用蒙特卡罗模拟来模拟线性衰减系数 (LAC) 和质量衰减​​系数 (μ/ρ)。同时，μ/ρ 和有效原子序数 (Z_eff ) 是使用 Phy-X 软件在 0.015 和 15 MeV 之间估计的。结果表明，μ/ρ和Z _eff遵循辉长岩>橄榄岩>辉石的顺序。在低能量下，所有研究的岩石都报告了最大 μ/ρ。发现 μ/ρ 值急剧下降，这表明岩石在低能量下具有更好的衰减，而在高能量下效果最差。橄榄岩的μ/ρ从11.540厘米减小² / g的0.015兆电子伏到5.122厘米² / g的0.02兆电子伏，1.681在0.03厘米² 0.814厘米/克兆电子伏，和² / g的0.04兆电子伏。在 0.015 MeV 时，橄榄岩的 Z _eff为 17.34，辉石岩的 Z _eff为 17.27，辉长岩的 Z _eff为_EFF的18.12。橄榄岩的半值层 (HVL) 从 0.015 MeV 时的 0.02 cm 减小到 0.04 MeV 时的 0.31 cm、0.20 MeV 时的 1.95 cm、1.00 MeV 时的 3.94 cm 和 15.00 MeV 时的 11.28 cm。然而，在所有能量中，辉长岩的 HVL 最少，其次是辉石岩和橄榄岩。
