Synthesis, structural properties and shielding efficiency of glasses based on TeO 2 -(1-x)ZnO-xSm 2 O 3

This paper presents the results of studying the properties of TeO2-(1-x)ZnO-xSm2O3 glasses synthesized using the method of mechanochemical synthesis and subsequent thermal sintering. The control of the elemental composition was carried out using the method of energy dispersive analysis, the amorphous structure of the glasses was confirmed by the data of the results of measurements of X-ray diffraction. The shielding efficiency was evaluated by such parameters as Radiation protection efficiency, linear and mass attenuation coefficient and gamma radiation absorption, half-value layer and mean free path values. During the research, it was found that TeO2-0.2ZnO-0.8Sm2O3 glasses had the highest shielding efficiency. The results obtained can later be used for the design of protective materials and the development of technological processes for their production.
