摘　　要：为测量5×103～1×1011Bq范围内的密封放射性γ源活度,研制了一套小体积密封γ源活度测量装置。描述了装置测量原理及装置的构成,并对装置进行了性能测试,实际测量了放射性γ源并评定了其不确定度。A set of apparatus for the measurement of 4πγ radiation activity have been developed in order to mea- sur the activity of sealed γ source of 5 × 103 - 1 × 1011 Bq . The paper describes the working principle and structure of the apparatus. The specifications and performances of the system have been tested and examined. The conventional true values of activity of -y source have been measured and its uncertainty has been assessed.
