Abstract

Radioactivity is the phenomenon that some unstable atomic nuclei change on their own, after which they release excess energy and emit nuclear radiation. Radiation can originate naturally, artificially, or from solar energy. Radioactive pollution causes many consequences for human health such as leading to some acute, chronic, or even fatal diseases if radioactive contamination in large doses, therefore, a material with good radiation shielding is required. The paper presents the results of research on the effect of the unit component on gamma radiation shielding efficiency of composite materials on E-128 resin. The results showed that the increase in the rate of fillers from 10 % to 15 % increases the effectiveness of radiation shielding. The best radiation shielding performance is when using 15% of PbO: Bi2O3: WC fillers (1:1:1 ratio), reaching 10.43 % with 60Co source and 9.19 % with 137Cs (efficiency equivalent to 77 % and 73 % of standard lead plate 0.25 cm thick).
