摘　　要：用电子自旋共振（ＥＳＲ）波谱技术对受￣（６０）Ｃｏ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．In this paper，the ESR spectra of American ginseng radiated by ^(60)Co have beenobserved for long time．The result shows，two or more than two kinds of instable freeradical and a stable free radical produced in American ginseng，when the radiationdose is beyond 12 kGy．Which indicateS permanence radiation damage of Americanginseng．The decay constants of instable free radical in American ginseng were meas-ured．
