摘　　要：设计60Coγ标准辐射校准装置，建立满足国家量值溯源和传递要求的标准辐射场，满足辐射监测和防护仪器仪表的检定与校准的要求。主要包括γ放射源、辐照器、定位系统、控制系统、安全连锁系统的技术要求和设计。该装置可以使被测探测器到放射源的距离能够严格准确地进行重复定位，确保量值传递时在不同校准点的几何条件严格一致。To set up a standard radiation field which meeting the national quantity traceability and delivery requirements, and meet the radiation monitoring and protecting instrument verification and calibration requirements, a 60Coγ standard radiation calibration device was designed. The contents mainly included the technical requirements and design of T-source, irradiator, positioning system, control system, safety interlocking system. The device could precisely measure the distance between the detector and the radiation source, ensuring the geometry conditions have no difference in different calibration points.
