This paper presents the results of a study of the efficiency of shielding gamma radiation with an energy of Co57 (136 keV), Cs137 (661 keV), Na22 (1274 keV) source by Bi2O3-TeO2-WO3 ceramics. During the studies of the shielding efficiency, it was found that an increase in the thickness of ceramics to 0.3–0.4 mm leads to a sharp increase in the shielding efficiency up to 25–50% of radiation, while the shielding efficiency for ceramics with a thickness of 0.1–0.2 mm was no more than 3–9%. The peculiarity of this work from the already known ones is that the conditions of synthesis and subsequent thermal sintering, selected experimentally, make it possible to obtain ceramics with a stable Bi2Te2W3O16 phase, while in most works the samples under study are amorphous or amorphous-like structures.
