Principle of Gamma Radiation Sterilization of plastic vaccine bottles

Plastic vaccine bottles are one of the main packaging for animal vaccines. Vaccines are different from ordinary items. They have strict requirements for packaging, among which sterility is very important. In terms of sterilization method, this kind of packaging will choose Gamma Radiation Sterilization.

Gamma Radiation Sterilization uses 60Co gamma rays to act on microorganisms, directly or indirectly destroying the nuclei of microorganisms, thereby killing microorganisms and playing a role in disinfection and sterilization. It is a type of radiation sterilization technology. The γ-rays produced by the radioactive isotope cobalt 60 are used to irradiate packaged food. In the process of energy transmission and transfer, powerful physical and biological effects are produced to achieve the purpose of insecticide and sterilization.

Gamma Radiation Sterilization has the advantages of strong penetration, uniform, thorough and rapid sterilization, no environmental pollution, low cost and low energy consumption. Plastic vaccine bottles sterilized in this way can achieve good sterilization effects without There will be drug residue. In my country, national standards have been formed for cobalt 60 sterilization technology. Currently, the standard GB10252-2009 "Radiation Protection and Safety Specifications for Gamma Irradiation Devices" is implemented, which is a relatively mature sterilization method.

Gamma Radiation Sterilization is only one of many sterilization methods for plastic vaccine bottles. Others include high-temperature and high-pressure sterilization and ethylene oxide sterilization. The specific sterilization method selected must be based on the requirements of the veterinary drug manufacturer and Depends on vaccine characteristics.
