摘　　要：介绍用6 0 钴γ数字辐射照相技术在线检查集装箱的方法与装置 ,包括检测系统的总体构思、结构、原理及性能。该系统采用γ射线源为 3～ 11TBq的常规6 0 钴工业探伤机 ,借助于所发明的高灵敏度阵列探测装置以及特殊低噪声前端电路和计算机信号与图像处理技术 ,其检测性能与加速器集装箱检测系统相当 ,而且占地小、价格低、易操作、易维护、辐射安全性好且可靠性极佳。The method for inspecting containers by 60 Co digital radiography and the relative apparatus are described including its idea, construction and performances. The radiation source used is a commercial 60 Co projector with the activity of 3—11 TBq. Depending on the highly sensitive array detector invented, the performances of the apparatus are as good as those of accelerator system. Nevertheless, 60 Co inspection system is smaller, cheaper, safer, more reliable and easier to operate and maintain. The practical applications have showed the prospect of its development.
