Electron Beam Sterilization

The irradiation dose is usually measured in grays but also in mr.

Electron beam sterilization.

Possible uses for electron irradiation include sterilization and cross linking of polymers. There are two basic system approaches used to sterilize medical devices with electron beam technology. The beam a concentrated highly charged stream of electrons is generated by accelerators capable of producing continuous or pulsed beams. Electron beam irradiation is a flexible and high speed process that can be used for a variety of applications including.

E beam services uses high power state of the art accelerators to create a powerful beam of electrons. In line and stand alone systems. Electron energies typically vary from the kev to mev range depending on the depth of penetration required. While most materials manufactured for use in the sterile healthcare products are formulated for radiation stability some materials certain polypropylenes for example experience less breakdown and long term aging effects as a result of e beam s shorter exposure time.

Sterilization of single use medical devices and pharmaceutical contamination control in packaging cosmetics and toiletries strengthening of polymers due to cross linking and or breaking down of polymers. As the product material being sterilized passes the e beam energy from the electrons is absorbed altering various chemical bonds damaging the dna and destroying the reproductive capabilities of the microorganisms. Electron beam processing or electron irradiation is a process that involves using electrons usually of high energy to treat an object for a variety of purposes. This may take place under elevated temperatures and nitrogen atmosphere.

An in line system is one in which the electron beam irradiation equipment is integrated directly into the production process.
