We experimentally investigated the effect of TeO2 on radiation-shielding competence a BaO–MoO3–B2O3 glass system. Two gamma-ray sources (137Cs and 166Ho) scintillator detector (sodium iodide (NaI(Tl)) were utilized to measure attenuation factors prepared at 0.184, 0.280, 0.662, 0.710, 0.810 MeV. The measured mass coefficient agreed well with theoretically calculated values for all samples. linear (LAC) results demonstrated that as photon energy increased, penetrating ability photons through increased. LAC boro-tellurite 662 keV compared those other tellurite glass. found MTB1 produced better than 10Li2O–20K2O–50B2O3–20TeO2 glass, whereas MTB5 70 mol% had an value greater 90.4TeO2-9.6ZnO–4NiO half-value layer (HVL) increased continuously energy. For HVL from 0.3609 cm 184 1.6078 1.8381 810 keV. lowest set was observed which confirmed its superior properties compositions. transmission factor (TF) also calculated; TF values, revealed provided best shield. thickness 1 cm, 75.8% MTB1, 72.8% MTB2, 70.6% MTB3, 68.8% MTB4, 63.4% MTB5.
