Exposure to electron beams can kill microbes making this technique useful for medical devices, medicine containers, food packaging and cosmetic container sterilization as well as many other kinds of products.
Electron beam processing has high treatment capacity and sterilizes preventing hazardous residues making it relatively high merit compared to other methods.
Directly damages the double-helix
structure of the DNA.
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.
