Abstract: Along with the development of nuclear medicine， radiation therapy is very important in the comprehensive treatment of tumor， but radiation damage is the main bottleneck restricting its development. National traditional Chinese medicine (TCM) master Professor Zhou Zhongying held that the etiology and pathogenesis of radiation injury was fighting of static blood and extreme heat， as well as deficiency of qi and yin under the guidance of the theory of stasis and heat. Radiation injury was characterized by burning pain， delayed traumatic， damaged collateral， impaired yin and qi. In TCM， the focus of it is usually classified by its location in head and neck， chest， epigastrium and hypogastrium. When it came to different foci， the clinical manifestation would be different. Hence， Professor Zhou regarded cooling blood and dispersing stasis along with nourishing yin and invigorating qi as its preventive and therapeutic principle.
