摘要
木材经６０Ｃｏγ射线辐照时，高聚分子的共价键断裂产生自由基，主谱ｇ０＝２．０１９３的自由基随辐照剂量Ｄ按指数率Ｎａ＝Ｎ０ａ（１—ｅ－ａａＤ）变化，最后趋于饱和。衰变系数ａａ与树种有关，远小于１。辐射引发自由基强度大，衰变系数小，稳定性好。具有应用前景。
Radiates wood by￣60Coγ radiation causing the cleavage of Co-valent louds wood polymers and generated free radicals.The intensity of free radicals of major spectrum increased exponetially with the radiation dose,N.a=Noa,and finally reached a saturation state.The decay coefficient aa was related to tree species in less than 1.The free radicals of wood induced by γ-radiation has great intensity and stability,and is worth for use.
