摘要
对目前微剂量测量中常用的组织等效正比计数器(TEPC)和基于绝缘体上硅(SOI)技术的微剂量计的特点和研究现状进行了分析,对比了二者的优缺点,指出TEPC在微剂量实验测量方面存在的缺陷。重点分析了SOI微剂量计的研究现状,对五代SOI微剂量计的物理设计结构作了详细说明,并对其在中子、质子和重离子微剂量测量方面以及组织等效转换方面的研究现状进行了详细分析,指出该技术目前存在的问题,并在此基础上对其发展前景进行了展望。
The characteristics and research status of the tissue equivalent proportional counter(TEPC)and the microdosimeter based on silicon-on-insulator(SOI)technology were analyzed.Based on the present technique,the performance of TEPC and SOI was compared,and the shortages of TEPC in the experimental measurement of microdose were pointed out.Several physical structures of the fifth generation SOI microdosimeter were explained in detail.Moreover,the research status for neutron,proton and heavy ion microdose and tissue equivalence were also analyzed.The problems of SOI microdose measurement technology were pointed out,and its development prospects were outlined.
