Abstract

A vehicle and cargo inspection system (VACIS) is described wherein fast-screening is achieved at low cost in a trade- off between cost, speed, resolution, reliability, transportability and power requirements. In its initial configuration, VACIS utilizes a shuttered Cs-137 source and a detector tower, or linear array, that travel along the cargo vehicle on trolleys that are moved by a common-source, variable-speed, synchronous motor drive. In another configuration, presently under development, the vehicle (such as a train) moves past the source and detector at both creeping and very high variable speeds. The variable velocity is constantly measured and is used as input to the image-generating program to produce undistorted gamma radiographs at 0.5 to 60 mph or more.
