Gamma Sterilization: Validation & Monitoring
Medical Device Testing Training Program
Gamma Radiation Sterilization
Gamma radiation is one of sterilizing agent used in sterilization process. It uses Cobalt 60 to kill microorganisms on medical devices. A dose is introduced to the samples for sterilization process. The unit for the dose is kiloGray, kGy.
Gamma Sterilization Validation
To achieve a sterile label claim product, an appropriate sterilization dose must be established. The sterilization dose shall be validated accordingly. At SaniChem, we offer a wide range of tests to help you validate your sterilization process in accordance with national and international standards.
Tests applicable:
-
Bioburden
-
Bacteriostasis/Fungistasis Test (B/F) or Method Suitability Test
-
Product Sterility

Gamma Sterilization Routine Monitoring (Dose audit) & Revalidation
Medical devices require careful and regular monitoring to assure sterility is not compromised. For Gamma sterilization dose audit, is it recommended to conduct in every three months. As for revalidation of sterilization, it is recommended to perform annually.
Tests applicable:
-
Bioburden
-
Product Sterility
-
Bacteriostasis/Fungistasis Test (B/F) or Method Suitability Test
