“…HVL value is an indicator of radiation protection performance. In other words, the lower HVL value of any material shows better radiation shielding performance as it will need a lower thickness [30]. A low HVL value indicates that the material has good protection properties [31].…”

In this study, calcium carbonate (CaCO3) was considered as nanoparticle. In the first part of the study, half-value layer (HVL) and mean free path (MFP) values, which are radiation shielding parameters, were investigated in determined energy ranges by Phy-X open access software. At increasing energy levels, the HVL value reached approximately 10 cm, while the MFP value reached approximately 17 cm. In the second part of the study, the reactor core geometry was modeled with the MCNP code and then the relative power distribution values were determined. COBRA code input was prepared with the determined relative power distribution values and thermal analyzes were made. These analyzes were performed for three different nanoparticle ratios. As a result of the analysis, the temperature value at the end of the channel was 613 K when only water was used as a coolant, while the temperature value at the end of the channel was 611.19 K when 0.03% nanoparticles were used. Although the coolant temperature increased with the nanoparticle ratio, it was observed that the temperature decreased when only water was used.

“…HVL of this composite was found to be 0.43, 0.78, and 0.63 times smaller than ordinary concrete, HDPE/20%nCdO composite, PE/20%CdS composite at 81 keV, respectively. However, it is also 21.3 times higher than lead [44,[53][54][55]. Figure 7b shows the TVL values of the composites for various energies.…”

The current study focused on investigating the gamma-ray shielding capacity of nano sized CeO2 (nCeO2) doped vinyl ester composites (VE/nCeO2) produced by the direct pouring method with different nCeO2 contents ranging from 2.5 to 20 wt%. X-ray Diffraction and Transmission Electron Microscopy were used to characterize the structural properties of nCeO2 particles. The gamma radiation shielding performance of the produced composites was investigated experimentally and theoretically within the scope of primary shielding coefficients like mass attenuation coefficient, half value layer, tenth value layer, mean free path, effective atomic number, and effective electron density. The experimental studies were obtained by NaI(Tl) scintillator detector for gamma-ray energies coming from Ba-133, Cs-137, and Co-60 radioactive point sources in the narrow beam geometry. The outcomes were compared with the theoretical calculations acquired by Monte Carlo N-Particle Transport version 6 code. The effective atomic number and effective electron density studies were additionally examined with WinXCom software. A good consistency between the experimental and theoretical outcomes was achieved. It was determined that among all composites, VE/20%nCeO2 composite having maximum nCeO2 content showed the best radiation shielding performance against all energy values. The nCeO2 additive was successful in enhancing the radiation attenuation performance of vinyl ester, and mass attenuation coefficients of investigated samples gradually changed from 0.15 to 0.79 cm2/g at 81 keV. The gamma-ray attenuation coefficients of the composites were compared with traditional shield materials and previously studied shielding materials and evaluated as promising lightweight, non-toxic alternatives for the low-energy gamma-ray shielding applications.
