摘　　要：讨论了总量测量的两种测量方法:脉冲计数和Time-to-Count,介绍了这两种方法的工作原理及优缺点,并利用这两种测量方法,分别设计了个人剂量仪,通过这两种仪器性能的比较,体现了Time-to-Count测量方法的优点。This paper discusses two measurement methods for the total measurement,i.e.,pulse-counting and Time-to-Count,and describes the working principles of these two methods as well as their advantages and disadvantages.Personal dosimeters which make use of these two measurement methods were designed.The advantage of Time-to-Count is reflected through a comparison of the performances of the two instruments.
