ملخص البحث المنشور:
In this study, high density polyethylene C2H4 (HDPE) was created utilizing additions of zinc oxide and titanium dioxide nanopowder in accordance with the HDPE(ZnO)x and HDPE(TiO2)x formulas, where x = 0, 2, 4, 6, 8, 10,12, and 15 mol%, respectively. The created samples were exposed to radiation from four typical point sources: 214 Am (59.5 keV), 133 Ba (303 and 356 keV), 137 Cs (661.7 keV), and 60 Co (1173 and 1332.5 keV). A sodium iodide (NaI (TI)) scintillation detector (2" × 2″) was used to measure the energy intensity. Experimental measurements and a calculation utilizing the WinXCOM database were used to determine the mass attenuation coefficient (μ/p) values for the prepared samples.
