Abstract
A detection system for an enclosed container for an enclosed cargo container includes a sensor device for sensing a material harmful to human beings within an enclosed cargo container and a detection device coupled to the sensor device for transmitting a corresponding signal to a monitoring device outside the cargo container. Containers which have harmful materials within them can be inspected or stopped before entering the country.
