Single-Use Technology >> Glossary >> G >> Gamma-sterilization


is the most frequently used sterilization method for plastics. The ionizing radiation amounts are between 12 and 50 kGy. The radiation penetrates the material and destroys the bioburden there 32. Thereby, a sterility security value of at least 10-6 must be reached according to ISO-standard 33. During gamma-sterilization the material further polymerizes. Protecting additives are necessary to avoid too strong oxidation or damage to the material 9. Cytotoxically active leachables and extractables can be built during gamma-sterilization 20.
