Tm2O3 doped tellurite glasses ((64.9-x)TeO2+15ZnO+10Bi2O3+10WO3+0.1Er2O3+xTm2O3) were prepared using the conventional melt-and-quench system. The glass samples, with varying concentrations of (x = 0 (TZBWET1), 0.4 (TZBWET2), 0.8 (TZBWET3), and 1.0 (TZBWET4) mol%) studied for their ability to absorb gamma radiation. mass attenuation coefficients (MACs) computed photons beams having energies E within range 0.015 ≤ 15 MeV popular accurate NIST-XCOM database. density TZBWET1, TZBWET2, TZBWET3, TZBWET4 is 6.006 g/cm3, 6.141 6.259 6.308 respectively. varied 0.036–57.990 cm2/g, 0.036–58.233 0.036–58.475 0.036–58.597 cm2/g TZBWET4, corresponding linear are 0.236–348.290 cm−1, 0.241–357.607 0.246–365.994 0.248–369.623 shielding potential improved addition Tm2O3. TZBWET showed better respect commercial thus environmentally friendly alternative available Pb-rich shields. study provided valuable insights into use as a promising material radiation applications, particularly in nuclear power, medical imaging, industrial radiography.
