Radiation-absorbing materials have long been a major issue and the use of various concrete compositions have resulted in several significant advancements. In this study, the gamma radiation shielding effectiveness of Ordinary Concrete with Low-Density Polyethylene (LDPE) and Polypropylene (PP) plastic waste fine aggregates were evaluated by determining the mass attenuation coefficient, half-value layer, absorbed dose, and depth dose. The EGSnrc code system was utilized to perform Monte Carlo simulation of Co-60 ionizing radiation transport, at photon energies 0.01-1.00 MeV through the concrete materials in narrow beam geometry.
The findings revealed that the radiation shielding capability of the materials are dependent on the amount of LDPE and PP incorporated into Ordinary Concrete. Both Ordinary Concrete with 5% LDPE and Ordinary Concrete with 5% PP are potentially suitable and alternatives for gamma radiation shielding, although there were differences in the mass attenuation coefficient of 1.651 and 1.719 percent and in the half-value layer of 2.452 and 2.514 percent, respectively, compared to pure Ordinary Concrete. Subsequently, the incorporation of plastic waste fine aggregates to Ordinary concrete increases its cost-efficiency. At the same time, the absorbed and depth doses of the two materials are likewise equivalent to those of Ordinary Concrete, supporting the assertion. A multi-layer material design on Ordinary Concrete with varying amounts of LDPE and PP plastic waste fine aggregates are recommended for future studies.
