Electron Beam Sterilization

The electron beam sterilization process begins with an electron beam accelerator.

Electron beam sterilization.

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. Electron beam e beam irradiation is a form of ionizing energy that is characterized by its low penetration and high dosage rates. An in line system is one in which the electron beam irradiation equipment is integrated directly into the production process. Possible uses for electron irradiation include sterilization and cross linking of polymers.

In line and stand alone systems. 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. This may take place under elevated temperatures and nitrogen atmosphere. The irradiation dose is usually measured in grays but also in mr.

The beam is scanned back and forth to create a curtain of fast electrons which shower and safely ionize the materials that they strike. E beam services uses high power state of the art accelerators to create a powerful beam of electrons. Electron energies typically vary from the kev to mev range depending on the depth of penetration required. Electron beam irradiation is a flexible and high speed process that can be used for a variety of applications including.

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.
