| 摘 要： | 用电子自旋共振(ESR)波谱技术对受60Co辐照后的西洋参样品进行了较长时间的跟踪观测,发现γ辐射在西洋参内产生两种或两种以上的不稳定自由基,井测定了它们的衰减速率常数;当照射剂量过大时,还将出现异常稳定的自由基.这表明在西洋参内产生了永久性损伤.

| 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. |
