Transport phenomena involved in the leaching of radioactive materials from a cement composite matrix are investigated using an empirical method with a polynomial equation. This study aims to assess the safety of radioactive waste cement compositions through the leaching of 137Cs and 60Co from waste composites into surrounding fluids, using methods recommended by the IAEA for conducting leaching tests. The research involves determining retardation factors (K F) and coefficients of distribution (k d) through a simplified mathematical model designed for analyzing the migration of radionuclides. Over a testing period of 60 days, the leaching mechanisms for 137Cs and 60Co were analyzed, yielding important results that are discussed in the context of a 25-year project focusing on mortar and concrete testing. The findings have significant implications for the design of engineered trench systems for a future radioactive waste storage center in central Serbia, contributing to enhanced safety in waste disposal practices.
