摘要/Abstract

摘要： X射线、γ射线照射后, 指甲内产生新的自由基, 通过电子顺磁共振(EPR)技术可以检测指甲中自由基团的信号, 形成电子顺磁共振波谱。本文介绍了指甲EPR波谱特征, 对比了离体和在体测量方法的特点, 重点介绍了在体测量方法及其在辐射剂量评估领域的应用优势。

Abstract: Following X-ray and γ-ray irradiation, new free radicals are generated in nails. These signals can be detected by the electron paramagnetic resonance (EPR) technique and form a spectrum. The EPR spectral characteristic of nails is introduced. The characteristic of in vitro and in vivo measurement methods is then compared, with which in vivo methods and their application advantages in dose estimation are highlighted.

Key words: Fingernail, Electronic paramagnetic resonance, in vivo measurement, Dose estimation
