The implementation of a backscattered X-ray landmine detection system has been demonstrated in laboratories at both Sandia National Laboratories and the University of Florida. The next step was to evaluate the modality by assembling a system for field work. To assess the system's response to a variety of objects, buried plastic and metal antitank landmines, surface plastic antipersonnel landmines, and surface metal fragments were used as targets. The X-ray machine used for the outside landmine detection system was a Philips MCN 225 industrial X-ray machine, which was operated at 150 kV and 5 mA and collimated to create a 2 cm diameter X-ray spot on the soil. The detectors used were two BICRON plastic scintillation detectors. The system was mounted on a gantry. Data generated from the detector responses were then analyzed to provide the images and locations of landmines. Changing from the lab environment to the field did not decrease the system's ability to detect buried or obscured landmines.
