Paper Abstract

Many different techniques have been investigated for detecting weapons, explosives, and contraband concealed under a person's clothing. Most of these are based on imaging the concealed object by using some sort of penetrating radiation, such as microwaves, ultrasound or electromagnetic fields.In spite of this effort by dozens of research groups, the only technique that has resulted in a commercially viable product is back-scatter x-ray imaging, as embodied in the SECURE 1000 personnel screening systems. The SECURE technology uses radiation levels that are insignificant compared to natural background values, being viewed as 'trivial' and 'completely insignificant' under established radiation safety standards. In the five years since the SECURE 1000 was developed, more than a dozen field trials and initial placements have been completed. This paper describes both the capabilities and limitations of the technology in these real-world applications.
