摘要

研究了γ辐照在猪骨中诱生的自由基的ESR波谱，并与紫外光辐照和未辐照处理的样品的ESR波谱作了比较。测得为辐照所特有的ESR信号。在实验使用的剂量范围内（1.23—6.24 kGy）,信号高度随吸收剂量增加呈线性地增加。样品分别在室温和-18℃以及空气存在下贮存45 d和22 d均观察到信号高度增加。

Abstract

The ESR spectra of radicals induced by γ-irradiation in pig bone have been studied and comparised with those of UV-irradiated and unirradiated samples. An ESR signal which is specific for irradiation has been found. The signal height increased linearly with the increase of dose within the range of 1.23 to 6.24 kGy. When the samples were stored at room temperature and -18℃as well as in the presence of air for 45 days and 22 days respectively, the growth of signal height has been also observed.
