Chapter 3: Gamma Irradiation Plants

This chapter focuses on the common components of gamma irradiation plants and specific design considerations for the irradiation of food. Experience is drawn from existing irradiators that process different food products globally, including both Category III and Category IV irradiator designs. The physics of dose penetration and dose distribution is discussed as it pertains to the design of gamma irradiation plants. Principles of safety in design and guidance provided in international standards are also discussed. Additional information is provided on economic aspects of gamma irradiation of food products.
