Radioactive waste has to be immobilized prior to storing it in a storage place. The sustainability and safety of an immobilized waste should be ensured. This paper will describe how several tropical materials can be used to achieve that objective. indonesia has plenty of natural resources, and the ability of its materials to immobilize strontium waste has been studied. The ability of zeolite as an adsorber on cement mortar had been studied. For increasing its compressive strength,
coconut (cocosnucifera) and bamboo (bambusavulgaris) fibers had been compared to increase mortar’s strength and durability, as well as rice husk ash as pozzolanic materials in theprevious study. The mortars were tested to determine their
compressive strength by using Universal Wood Testing after being cured for 28 days. Strontium leaching rate encapsulated on the blocks was analyzed by using Hitachi Zeeman 8000 Atomic Absorption Spectrophotometer for 21 days. This
research showed several materials that can be found in Indonesia, such as zeolite, natural fibers, and rice husk, are able to be used for immobilizing strontium waste. Cement mortar containing these materials can meet IAEA standards for compressive strength and strontium leaching rate of cementation, and hence the safety of strontium waste immobilization can be ensured.
