Abstract: 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.

Key words: microdose, tissue equivalent proportional counter (TEPC), SOI microdosimeter
