The proposed study summarizes the results from the investigation carried out on fiber reinforced copper slag concrete with steel, basalt fibers, and in hybrid form subjected to gamma radiation shielding. The part of the research work has been previously published in which the detailed mechanical investigations of the proposed concrete were carried out. From the previous investigations, the optimum volume fraction of the fibers was identified and fused in concrete to analyze the gamma radiation shielding parameters. Due to the increased density and the spiked vital elemental composition in concrete made it reliable to study the gamma radiation properties. The present study focuses on parameters such as linear attenuation coefficient, mass attenuation coefficient, half value layer, tenth value layer, and mean free path. The hybrid and mono fiber concrete was subjected to the gamma source Iridium (192Ir), and it was observed that basalt as mono fibers in concrete established greater shielding properties followed by the steel and basalt fibers in hybrid form.
