초록
This study was to investigate the effect of ionizing radiation on the structure and filtrationperformance of KF94 respiratory mask using the 2.5 MeV electron beam accelerator. From the SEMand TGA analyses, all filters showed no significant and measurable structural changes irradiated up to24 kGy in air and vacuum conditions. However, compared to the pristine KF94 mask, filtration efficiencyof electron beam treated KF94 masks was decreased from 99.4% to ~55~67% due to the reduction ofelectrostatic force by ionizing radiation.
