![]() In addition to irradiation sterilization, STERIS AST provides our Customers with laboratory testing and technical support solutions at every stage of the sterilization design process, from product development through routine processing. Gamma sterilization is supported by the internationally recognized consensus standard, ISO 11137, which describes the approach to validating a dose to achieve a defined sterility assurance level (SAL). With the ability to penetrate products while sealed in their final packaging, gamma irradiation supports the manufacturing and distribution process by facilitating final packaged products as well as raw material needs, ensuring full sterility of the product. Gamma irradiation is safe, reliable and highly effective at treating a wide variety of products with varying densities. Some examples of products processed include:įor a comprehensive list of products commonly treated by gamma irradiation, please see Technical Tip # 4 What are the Benefits of Gamma Irradiation? The gamma irradiation process can effectively treat a wide variety of products composed of different materials, with varying densities, configurations and orientations. Delivery and absorption of dose by product is determined by product density, packaging size, dose rate, exposure time and facility design. The unit of absorbed dose is kiloGray, expressed as kGy. A key characteristic of gamma irradiation is the high penetration capability, which allows for delivery of target radiation dose to areas of products that may be higher in density. Gamma radiation is generated by the decay of the radioisotope Cobalt 60, with the resultant high energy photons being an effective sterilant. The gamma irradiation process uses Cobalt 60 radiation to kill microorganisms on a variety of different products in a specially designed cell. Gamma irradiation offers good penetration of dense products and is ideal for many types of materials and their packaging. The gamma irradiation process uses Cobalt 60 radiation for a variety of applications, including sterilization, decontamination and materials modification.
