摘　　要：针对国内数字电子个人剂量计种类繁多、测量原理不同导致其性能差异显著进而不利于个人剂量的有效监督的情况。按照国家标准和规程要求,设计新一代个人剂量计Nt2000,并在标准辐射场中对该仪器进行了相对固有误差、剂量线性、重复性、能量响应和角响应测试。测试结果表明：Nt2000个人剂量计主要性能指标满足国标要求,能量响应（48--1 250 ke V）优于±28%,可部分替代国外同类仪器。As the domestic digital electronic personal dosimeters have many types, and different measurement principle, resulting in a significant difference in performance, so it is not conducive to effective supervision of individual doses, For the above, in accordance with national standards and procedures requirement, Sichuan Radiation Technology Co., Ltd design a new generation of personal dosimeters Nt2000, and test the instrument with the relative intrinsic error, dose linearity, repeatability, energy response and angular response technology in the standard radiation field. Testing results show that the performance of personal dosimeters Nt2000, energy response （48-1250 keV）better than ±28%, is not only meeting the requirements of GB, but also can replace imports personal dosimeters.
