Abstract
To study the effects of radiation sterilization of the electron beam， the three species of microorganisms， Escherichia. coli， Staphylococcus aureus and Proteus vulgaris were irradiated with the electron beam, delivered by the electron accelerator independently developed by the Institute of Modern Physics， Chinese Academy of Sciences， and the changes of superoxide dismutase (SOD) activity of these irradiated microorganisms were also tested. The results indicated that the Staphylococcus aureus were fully radiosterilized with the radiation dosage of 2.0 kGy, but 2.2 kGy to the Escherichia.coli and Proteus vulgaris. Moreover， the data also demonstrated that the irradiation had noticeable effects on the SOD activity of the three microorganisms.
