辐射监测设备在国土安全、核事故应急、环境监测等领域有广泛的应用，对于防止核扩散、降低核恐怖主义威胁、保障国民安全具有突出的意义。本文对美国国土安全部（ DHS）实行的辐射监测设备性能测试评估体系做了介绍。国家核探测办公室（ DNDO）开展了GRaDER项目，通过国家实验室自愿认可程序（ NVLAP）认可的实验室运行，以ANSI／IEEE N42系列标准为主要依据。这一体系及其运行的成功经验对我国具有借鉴意义。

Radiation detectors are widely used in homeland security, nuclear emergency, environmental monito-ring and other fields, as a significant tool for prevention of nuclear proliferation,reducing the threat of nuclear terrorism and protection of national security.In this paper, the performance testing and evaluation system of ra-diation detectors by the U.S.Department of Homeland Security ( DHS) is introduced.The National Nuclear Detection Office ( DNDO) established Rad/Nuc Detector Evaluation and Reporting ( GRaDER) Program to e-valuate commercial Rad/Nuc detection equipment against ANSI /IEEE N42 consensus standards adopted by the Department of Homeland Security, using National Voluntary Laboratory Accreditation Program ( NVLAP) lab accreditation process to confirm test lab capability and competence.These can be significantly used for ref-erence for the similar work in China.
