After the decommissioning of JMTR, the geopolymer treatment method for difficult waste ion exchange [1]. The potassium and metakaolin-based geopolymer is irradiated by ETIGO-Ⅲ at room temperature from one to four shots. The Vickers hardness were decreased after irradiation but did not affect by the number shots. The current results show the stability of metakaolin-based geopolymers under electron irradiation.
