摘要

X-射线与γ-射线照射后，指甲作为放射敏感性好的生物材料，会产生一定量的自由基。电子顺磁共振(Electron paramagnetic resonance, EPR)作为一种可以定性及定量研究自由基的工具，用来检测指甲中由于辐射引起的自由基含量，进而估算人群受照剂量，在放射性事故中对人群分类验伤，作为一种未成熟的剂量学方法存在一定的问题，而有些研究人员对于定量使用EPR不是十分熟悉，因此，本文将讲解定量实验的理论基础、需要注意的地方和目前的最新进展以及未来的研究方向。

Abstract

After X-rays or γ-ray irradiation, fingernails as biomaterial having good radiosensitivity, would generate free radicals. Electron paramagnetic resonance (EPR), a tool which can qualitatively and quantitatively measure free radicals, has been used to detect the radical concentration induced by irradiation so that estimate irradiated dose of victims and conduct triage. As an immature dosimetry method, it still has many problems, and some researchers are unfamiliar with quantitative utilization of electron paramagnetic resonance. Therefore, the theory, matters needing attention and recent progress of fingernail electron paramagnetic resonance quantitative measurements will be reviewed.Cited
