This work investigated the radiation attenuation characteristics of three series of tellurite glass systems with the following compositions: 30PbO-10ZnO-xTeO2-(60-x)B2O3 where x ¼ 10, 30, 40, 50 and 60 mol%, xBaOexB2O3e(100-2x)TeO2 with x ¼ 15e40 mol% and 50ZnOe(50-x)P2O5exTeO2, where x ¼ 0, 10, .40 mol%. The results revealed that the attenuation parameters in all the samples decrease with increase in the energy, which implied that all the samples have better interaction with gamma photons at low energies and thus higher photon attenuating efficiency. From the three systems, the samples coded as PbZnBTe60, BaBTe70 and ZnPTe40 have the lowest half value layer values and accordingly have superior photon attenuation efficacy. The maximum effective atomic number values were found for energy less than 0.1 MeV particularly near the K-edges absorption of the heavy atomic number elements such as Te, Ba and Pb. At the lowest energy, the Zeff values are found in the range of 62.33e66.25, 49.43e50.81 and 24.99e35.83 for series 1e3 respectively. Also, we found that the density of the glass remarkably affects the photon attenuation ability of the selected glasses. The mean free path results showed that the PbO-ZnO-TeO2-B2O3 glass system has better radiation shielding efficiency than the glass samples in series 2 and 3.
