Gamma Sterilization

Gamma radiation treatment is best suited for sterilizing packaged products with low to high density, as well as products with complex geometries. 

Gamma rays are produced by the decay of a radioactive isotope, usually cobalt-60 (60Co). They have a high penetration depth at low dose rates and thus have the special ability to penetrate entire pallets and containers. The products to be sterilized can usually be passed through the irradiation process directly on the delivery pallets. Gamma rays destroy the DNA of microorganisms, making them harmless - due to physical limitations, no radioactivity is generated in the process. After treatment, the products are completely free of residues and can be used immediately.
