摘要: 微剂量学是交叉学科的新兴领域,研究粒子在物质中能量沉积的微区分布和放射生物学效应,本文主要对微剂量学研究的进展,包括粒子的径迹结构,能量沉积和微剂量学实验技术等方面作一概述。 Microdosimetry is a rapidly developing field in the multi-disciplines. It studies energydeposition processes in media with particular interesting to living system. This paper gives short reviewon the recent progress in the study of microdosimetry including the track structure of ionzing particlesenergy deposition and new microdosimetric experimental techniques.
