摘　　要：聚酯薄膜 (PET)作为由C ,H ,O三种元素组成的有机物 ,与生物组织的组成较为相似 ,测量单能电子在PET中的射程在放射性防护方面有一定的价值 .本文在RES系列相对论效应实验谱仪平台上测量了单能电子在PET中的射程 ,给出了相应的实验方法和数据处理方法 ,实现了在普通实验室进行单能电子射程的测量 .Mylar (PET), which is composed of carbon, hydrogen and oxygen, is similar to the organic compound. Measuring the range of single-energy electrons in PET means much to the radioprotection. Using RES serial relativity effect spectrometer, the range of single-energy electrons in PET is measured. The method of experiment is designed, and the way of data processing is given. The experiment demonstrates the feasibility of measuring the range of single-energy electrons in a common lab.
