| Radiation Sterilization Dose Setting | ||
| Introduction | Irradiation sterilization is an effective method to kill most microorganisms on substances using electromagnetic waves generated by ionizing radiation. The radiation used for sterilization includes electron beams, X-rays and gamma rays. All of them can control microbial growth or kill microorganisms in specific ways. X-rays and gamma rays can oxidize other substances or produce free radicals (OH·H) and then act on biological molecules, or directly act on biological molecules, break hydrogen bonds, oxidize double bonds, destroy ring structures or polymerize some molecules, and destroy and change the structure of biological macromolecules, thereby inhibiting or killing microorganisms. | |
