irradiation sterilization is an FDA-approved terminal sterilization method for medical supplies. At present, 40-50% of disposable medical products produced in developed countries are sterilized by radiation (IAEA,2008). After long-term research, scientists have proved that radiation sterilization is a safe and reliable method, which can effectively kill bacteria and viruses including anthrax. Low carbon, energy saving, environmental protection is the main theme of the times, irradiation technology to replace EO sterilization is the trend. Compared with EO sterilization, irradiation sterilization has the following advantages:
, no chemical residue, will not harm human health;
, irradiation processing can be put into sales, without a long time of chemical residue analysis process.
