This paper presents a mobile 60Co container inspection system (CIS) and its performance. With all devices including industrial 60Co source

high sensitive gas-ionized array detector

image treatment and control system

inspection driving device on a vehicle

the vehicle mobile CIS has advantages of high agility and climate resistance

and it can complete emergent inspection. The mobile CIS contains equipment-vehicle and control-vehicle. Equipment-vehicle and object-container are still

while a folding detector gantry is moving through a folding rail on the equipment-vehicle and completes the inspection. The mobile CIS has the inspection characteristics similar to the fixed system and it can be used in worse circumstances. Its CI (Contrast Indicator) and IQI (Image Quality Indicator) for 100 mm steel plate attain to 0.5 % and 2.5 % respectively

and the SP (Space Penetration) is about 240 mm (Fe). Maximum dose per scanning is about 5 μ. Gy

scanning speed is varied from 6 to 18 m/min

and maximum transformational speed is 90 km/h.
