Abstract: Electron beam (E-beam) sterilization is widely applied to polymer-based medical devices, yet its impact on microplastic release remains insufficiently understood. This study examines dose-dependent degradation and microplastic leaching from natural rubber latex Foley catheters irradiated at 25–100 kGy. Surface morphology (E-SEM), total organic carbon (TOC), dynamic light scattering (DLS), and microbial assays were used to evaluate structural and functional changes. Increasing irradiation dose resulted in progressive surface cracking and elevated TOC, with nanoplastics detected at ≥ 75 kGy. Irradiated microplastics also showed reduced microbial growth. The findings highlight the need to balance sterilization efficacy with material stability to minimize microplastic release. [ABSTRACT FROM AUTHOR]
