Abstract: THE SELECTION OF ELECTRON BEAM RADIATION ACCELERATORS AND TECHNICAL ECONOMY ANALYSIS OF RADIATION PROCESSINGCui Shan；Yang Juntao（chian Institute of Atomic Energy,Beijing 102413）ABSTRACT Different types，main parameters and application fields of electron beam accelerator are btiefly in-troduced．The selection of accelerator parameters should consider the dosage，penetration depth，sizeand shape of products and the production capacity. Technical and economical analysis of electron beamprocess is compared with the other competitive process. Current progress and future trend of radiationprocessing are also described.Key worlds electron beam radiation processing radiation accelerator technical and economi-cal analysis
