Abstract: In this paper,the ESR spectra of American ginseng radiated by 60Co have been observed for long time.The result shows,two or more than two kinds of instable free radical and a stable free radical produced in American ginseng,when the radiation dose is beyond 12 kGy.Which indicates permanence radiation damage of American ginseng.The decay constants of instable free radical in American ginseng were measured.

Key words: American ginseng, Radiation, Electron spin resonance
