摘要

对20、200、500 mesh毛竹试样进行γ射线辐照和ESR自由基强度测定

g=2.0033。毛竹辐照的自由基强度随吸收剂量按指数规律增加

吸收剂量100kGy时

自由基强度是机械自由基的40倍

3组试样的自由基衰变系数各不相同。

Abstract

Bamboo samples collected in mountain areas of Fujian province were mechanically pulverized into saw dust.This breaks the covalent bonds of bamboo molecules and free radicals are formed.ESR characterization of the bamboo saw dust samples of 20

200 and 500 mesh showed that the relative intensity of the 500 mesh saw dust was the highest

and that of the 20 mesh was the lowest（g=2.0033）.After

Coγ-ray irradiation

the intensity of free radicals increased sharply.At

100 kGy

the free radicals tended to be saturated at about 40 times of the free radicals produced mechanically.The intensity of free radicals increased exponentially with the dose below 100 kGy

and decay coefficients of the free radicals in the three samples were different.
