“…The ECS values are 8.03, 9.15, 4.70, 6.66 and 14.8 × 10 −24 cm 2 /g at 0.1 MeV then they decrease to 2.36, 2.39, 2.23, 2.29 and 2.62 × 10 −25 cm 2 /g at 1 MeV. A similar result had been observed in our previous work [40]. In Table 2, one can notice that CuI has maximum penetration of gamma photons while HgI has less penetration probability and more probability of interaction with gamma photons.…”

“…CuI sample has the highest corresponding value related to their inverse proportion to the average material atomic weight. All tested samples values are higher than the corresponding CdTe [43], CdSe [43] and Cu 2 MnGeTe 4 [40] values and lower than Cu 2 MnGeS 4 [40] value at nearly 15 keV. A similar result had been observed in our previous work [40].…”

“…In Table 2, one can notice that CuI has maximum penetration of gamma photons while HgI has less penetration probability and more probability of interaction with gamma photons. Our samples have more probability of interaction than CdSe [43], Cu 2 MnGeS 4 , Cu 2 MnGeSe 4 and Cu 2 MnGeTe 4 [40] samples. Figure 9 illustrates N eff changes for all examined specimens with photon energy in the selected range.…”

“…The lowest levels for HVL have been found at 15 keV, equal to 0.0013, 0.0015, 0.002, 0.0025, and 0.0007 cm for the samples from S1 to S5. In our previous work, at 15 KeV, HVL values equal 0.003, 0.002 and 0.002 for Cu 2 MnGe [S, Se, Te] 4 , respectively [40]. At 15.8 KeV, it equals 0.0021 cm for CuInSe 2 [41].…”

This analysis aims to determine photon attenuation for five different ternary and binary iodide compounds using Phy-X/PSD software. For a broad range of photon energies between 0.015 and 15 MeV, the mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), half-value layer (HVL), tenth-value layer (TVL), and mean free path (MFP) for the samples of Cu2HgI4, Ag2HgI4, CuI, AgI, and HgI were calculated. For illustration, the following values of TVL apply at 1 MeV: S1: 6.062 cm, S2: 6.209 cm, S3: 6.929 cm, S4: 6.897 cm, and S5: 4.568 cm. Some important parameters, such as total atomic cross-sections (ACS), electronic cross-sections (ECS), the effective atomic numbers (Zeff), effective electron density (Neff), and effective conductivity (Ceff) of the samples were also calculated. Additionally, exposure buildup factors (EBF) and energy-absorption buildup factor (EABF) were estimated. These data on the radiation characteristics of our samples could be useful for gamma attenuation. The HgI sample has the highest FNRCS values (0.0892) relative to the other tested samples showing good neutron attenuation features. The CuI sample shows low gamma attenuation features; in contrast, it shows high neutron attenuation features.
