Study on design of radiation-shielding concrete mix using barite aggregates for Cobalt-60 radiation source

Abstract

Concrete material is commonly used in construction works, in addition to being used as a radiation shielding material in radiation imaging facilities. In this study, we design a barite-aggregated concrete mix with the density from 2.4 g/cm³ to 3.2 g/cm³,this concrete's radioactive resistance value is equal to irradiation with a cobalt 60 gamma source on the sample. The design of concrete mix with different densities helps to reduce material thickness, increase the usable area while ensuring the bearing capacity of the structure and ensuring radiation safety for construction items.
