Exposure to electron beam irradiation will kill microbes (sterilization), making this technique beneficial for medical devices, medicine containers, food packaging, and cosmetic containers among many other products.
Electron beam processing allows for high-capacity product treatment. The sterilization does not leave a residue, making EB a preferred treatment versus other methods.

EB Sterilization Principles

Direct Effects

Directly damages the double-helix
structure of the DNA.

Indirect Effects

Oxidizes and reduces
materials damaging the cells.

DNA is damaged by two effects of exposure to electron beams.
The first effect is direct damage to caused to the double-helix structure of DNA. The second is that electron beams also split water molecules in cells, generating radicals that cause indirect damage.
