The Role of La<sub>2</sub>O<sub>3</sub> in Enhancement the Radiation Shielding Efficiency of the Tellurite Glasses: Monte-Carlo Simulation and Theoretical Study
The radiation shielding competence was examined for a binary glass system xLa<sub>2</sub>O<sub>3</sub> + (1 − x) TeO<sub>2</sub> where x = 5, 7, 10, 15, and 20 mol% using MCNP-5 code. The linear attenuation coefficients (<i>LAC</i>s) of the glasses wer...

| description | The radiation shielding competence was examined for a binary glass system xLa<sub>2</sub>O<sub>3</sub> + (1 − x) TeO<sub>2</sub> where x = 5, 7, 10, 15, and 20 mol% using MCNP-5 code. The linear attenuation coefficients (<i>LAC</i>s) of the glasses were evaluated, and it was found that LT20 glass has the greatest <i>LAC</i>, while LT5 had the least <i>LAC</i>. The transmission factor (TF) of the glasses was evaluated against thicknesses at various selected energies and was observed to greatly decrease with increasing thickness; for example, at 1.332 MeV, the TF of the LT5 glass decreased from 0.76 to 0.25 as the thickness increased from 1 to 5 cm. The equivalent atomic number (Z<sub>eq</sub>) of the glasses gradually increased with increasing photon energy above 0.1 MeV, with the maximum values observed at around 1 MeV. The buildup factors were determined to evaluate the accumulation of photon flux, and it was found that the maximum values for both can be seen at around 0.8 MeV. This research concluded that LT20 has the greatest potential in radiation shielding applications out of the investigated glasses due to the glass having the most desirable parameters. |
