Description
The advancement of time, which comes along with the evolution in technology, necessitates a targeted research focus for various applications. In material science and the use of materials for various applications, radiation and shielding are critical aspects to deal with, especially for the health of the users. Attenuation of harmful electromagnetic radiation is of great importance. In this work, we report the results of the investigation of the radiation shielding properties of a lead-free, rare-earth-based, Er₂Os₂O₇ compound. A well-characterized powdered sample was investigated through NIST XCOM and Phy-X for radiation shielding properties. The mass attenuation coefficient (MAC) results ranged from 3.398 cm²/g at 0.1 MeV to 0.042 cm²/g at 10 MeV, indicating that Er₂Os₂O₇ is a better photon shield at low energies. The HVL and TVL values further show that Er₂Os₂O₇ has better photon shielding capabilities when compared to ceramic glasses, lanthanide-based ceramics, and germanate glasses. However, the MAC and LAC values further confirmed that this material is not a good neutron shielding material.
