| Abstract: | This paper presents a special container scanner in which the radiation source is a conventional radiography 60Co projector of (100-300)×3 .7×1010Bq. With a specia l sensitive array detector, invented by Institute of Nuclear Energy Technology ( INET) of Tsinghua University and other technical innovations, t he characteristics of the 60Co scanner qualify it for use in c ontainer insp ection. Its contrast indicator (CI) and image quality indicator (IQI) for 10 0 mm steel are equal to 0.7% and 2.5%, respectively, and the steel penetration ( SP) is about 240 mm. The 60Co container scanner is much more ec onomical and more reliable than those scanners using an accelerator source. Also, its penetr ation ability is much better than that of an X-ray machine scanner. This paper p resents the system design, the main difficulties and their technical solutions, the inspection characteristics and the special features of the 60Co sc anner. |
