NEW DESIGN OF CO-60 SOURCE FOR WET GAMMA-IRRADIATORS

Co-60 sources represent one of the key factors in industrial radiation processing and applications such as sterilization of disposable produ cts and food preservation. Design of the sources being currently used in wet gamma irradiators can be improved with the purpose of increasin g the source corrosion stability and mechanical integrity during use. This paper describes the proposed new design of Co-60 source for wet g amma irradiators. As a result of changes in capsule material and some dimensions, product quality and reliability can be improved with no ad ditional cost for end user.
