Radiation protection seeks to prevent the negative consequences of ionizing radiation by reducing unneeded exposure. A widely established principle for working assure safety, goal this study is optimize protection. In study, high density polyethylene C2H4 (HDPE) was created utilizing additions zinc oxide and titanium dioxide nanopowder in accordance with HDPE(ZnO)x HDPE(TiO2)x formulas, where x = 0, 2, 4, 6, 8, 10,12, 15 mol%, respectively. The samples were exposed from four typical point sources: 214 Am (59.5 keV), 133 Ba (303 356 137 Cs (661.7 60 Co (1173 1332.5 keV). sodium iodide (NaI (TI)) scintillation detector (2" × 2″) used measure energy intensity. Experimental measurements a calculation WinXCOM database determine mass attenuation coefficient (μ/p) values prepared samples. findings experiment hypothesis found be highly similar. sample combination 15% ZnO HDPE demonstrates superior efficacy shielding against gamma radiation. level 1.332 MeV associated rise fraction nanoparticles, which turn leads 20% increase coefficient. Finally, it should noted that half value layer saw decrease 34% when concentration nanoparticles increased at an MeV. It can deduced proportion nanoparticles.
