Radioactive waste processing is still a challenge in the use of radioactive materials. Radioactive waste is toxic and carcinogenic, so it cannot be disposed directly into the environment. HKUST-1 is a material that has the potential as an adsorbent for radioactive waste. However, research on HKUST-1's resistance to radiation has yet to be widely carried out. In this study, the resistance of HKUST-1 was tested by electron beam irradiation using four different doses, namely 50, 100, 125, and 150 kGy. SEM, XRD, and isothermal adsorption tests were then carried out to determine the characteristic changes in HKUST-1. The test results for the characteristics of the electron beam radiation affect the changes in the characteristics of HKUST-1. The crystal adsorption quality decreased in the irradiation dose range of 50 to 125 kGy, indicating amorphization. It was found that there was a possibility of crystallization due to the influence of electron beam irradiation at doses of 50 and 150 kGy, which led to increased adsorption quality at these doses. The best adsorption quality in this study was HKUST-1 which was irradiated with the highest dose, namely 150 kGy with an average adsorbed gas volume of 332.05 cc/g, surface area of 947.747 m2/g, and pore volume of 0.5586 cc/g.
