Gamma Beam Irradiation
A widely accepted sterilization method for your product
Gamma ionizing irradiation, is generated by the decay of the radioisotope Cobalt 60, with the resultant high
energy photons being an effective sterilant for a wide variety of medical device products.
Mechanism of Action
As with all forms of irradiation sterilization, Gamma Beam Irradiation contacting product bio-burden, causes
the break up the RNA/DNA of the bioburden, eliminating their ability to function and reproduce.
Benefits
- Able to penetrate more densely packaged products
- Temperature is moderate process parameter with mild effects for sensitive
materials and sterilization is effective even with frozen items
- Does not require any permeable membrane packaging that is necessary with
chemical sterilization methods allowing fully packaged materials, even some liquids, to be
sterilized
Limitations
- Polymers may experience embrittlement, discoloration and degradation from
induced molecular cross-linking, which can easily be tested for stability assurance.
- High-speed particle impact may destabilize NV-ram and logic gates on
non-shielded semiconductors and other electronics
