To assess the safety of disposal of a radioactive waste-cement composite, the leaching of 137Cs from a waste composite into a surrounding fluid has been studied. Leaching tests were carried out in accordance with a method recommended by the IAEA. The leachability was measured as a function of the bentonite clay to cement ratio. The fraction of 137Cs leached from a specimen of Portland cement ranged from 0.03 to 0.13 at a leaching time of 400 days. Results presented in this paper are examples of data obtained in a 10-year mortar and concrete testing project, which will influence the design of the engineered trench system for a future Yugoslav radioactive waste storage center. This research highlights the importance of optimizing cement formulations to minimize the leaching of radionuclides, thus ensuring prolonged stability and containment of hazardous materials.
