Radiation processing is a relatively sophisticated industrial technique to make products of good quality which cannot be manufactured by the conventional thermal and chemical processes. The radiation-induced changes in polymer materials such as plastics or elastomer provide some desirable combinations of physical and chemical properties in the end product. Radiation can be applied to various industrial process involving crosslinking, curing and sterilization. Current commercial usage for radiation processing in Korea is dominated by several major applications: crosslinked wire, shrinkable tube, procuring of some automobile tire components, curing of surface coating, polyolefin foam, PTC conducting polymer, sterilization of disposable medical products. A New National Core Research Center for R&D of Radiation Technology in Jeongup, Chollabukdo Korea will be constructed until the year of 2005 in order to meet the rapidly growing market in the areas of radiation technology. This report describes an overview of commercial radiation processing and research works carried out in Korea.
