MOBILE CONTAINER INSPECTION SYSTEM

 

 

 

 

 

1. Introduction

The Mobile Container Inspection System is a truck-mounted non-intrusive container inspection system with completed and advanced inspection features, excellent performance and flexible mobility.

The inspection system comprises a cobalt-60 gamma ray source, a solid detector array, a signal and image processing subsystem, a scanning vehicle with installed scanner, a driving and control subsystem, a generator and distribution subsystem and a radiation protection and safety subsystem.

All of the facilities are installed in a truck to perform efficient and high quality container inspection at different checkpoints in one port or between neighbor ports so as to detect explosives and arms for security enhancement as well as expose contrabands and drugs in smuggling or fraud.

The Mobile Container Inspection System is a highly advanced radiation imaging technology using cobalt-60 source and solid detector for screening trucks, cargo containers and passenger vehicles for contraband and explosives.
