Abstract
- We have attempted to develop the gamma radiation shielding abilities of newly prepared epoxy composites by introducing ZrO<subscript>2</subscript>. The radiation shielding parameters are experimentally reported below. The experimental setup included an HPGe detector and different radioactive point sources which emitted photons with energies of 0.06, 0.662, 1.173, and 1.333 MeV. The gamma radiation shielding abilities of the epoxy composites were examined in the context of the linear attenuation coefficient (LAC), half-value layer (HVL), radiation absorption ratio, and other factors. The experimental and Phy-X results for the LAC were compared, and acceptable consistency was reported. The lowest LAC values were reported for EBZr-0 (free of ZrO<subscript>2</subscript>), and we found that the photon attenuation competence of the present epoxy improved as a result of increasing the ZrO<subscript>2</subscript> content. We compared the LAC values for the present epoxy composites with other samples, and we found that the prepared composites with 20% to 40% ZrO<subscript>2</subscript> had higher LAC values than epoxy with 30% Yahyali Stone. The HVL lengths of the epoxy composites reduced with the addition of ZrO<subscript>2</subscript> for the four selected energies, which confirmed that introducing ZrO<subscript>2</subscript> improves the radiation absorption abilities of epoxy composites. At 0.06 MeV, the HVL for the ZrO<subscript>2</subscript>-free epoxy was 2.60 cm, which fell to 0.23 cm after adding 40% ZrO<subscript>2</subscript>. The mean free path (MFP) for the prepared composites was less than 1 cm at 0.06 MeV (standard for EBZr-0), while it was 1.32 cm for EBZr-10. For the other energies, it was higher than 6 cm, and became higher than 10 cm at 1.333 MeV for all composites. The obtained results suggest that non-toxic, natural, and cheap epoxy composites with high ZrO<subscript>2</subscript> content have the potential to improve the gamma ray shielding competence of epoxy composites for low energy radiation applications.
