ADVANCES IN METHODS OF GENERATING AND DETECTING X-RAYS MOTIVATED AN INVESTIGATION OF THE USE OF THIS TECHNOLOGY IN THE AREAS OF CRIMINALISTICS AND NATIONAL SECURITY.

Abstract

SPECIFICALLY, THE ADVENT OF RADIOISOTOPE SOURCES FOR X-RAY GENERATION PERMIT THE CONSTRUCTION OF SIMPLE-TOUSE, COMPACT, PORTABLE SYSTEMS SUITABLE FOR USE IN THE FIELD BY LAW ENFORCEMENT PERSONNEL. TO ASCERTAIN POTENTIAL APPLICATIONS A SURVEY INVOLVING FOURTEEN GOVERNMENT AND NONGOVERNMENT LAW ENFORCEMENT AND SECURITY AGENCIES WAS CARRIED OUT. THIS REVEALED NINETEEN PROBLEM AREAS OF WHICH EIGHT APPEARED AMENABLE TO SOLUTION VIA THE USE OF X-RAY FLUORESCENCE METHODS. OF THESE, SIX WERE SELECTED FOR FURTHER STUDY ON THE BASIS OF FEASIBILITY AND THE EXTENT OF POTENTIAL USE. BASED ON THE RESULTS OF THIS STUDY TWO AREAS - BULLET HOLE IDENTIFICATION AND COVERT MARKING WERE DESIGNATED AS FIRST PRIORITY APPLICATIONS. ACCORDINGLY, PROTOTYPE MODELS OF PORTABLE X-RAY SYSTEMS CAPABLE OF FIELD USE WERE DESIGNED, CONSTRUCTED AND TESTED FOR THESE TWO USES. A DESCRIPTION OF THESE SYSTEMS, THEIR THEORY OF OPERATION AND DIRECTIONS FOR THEIR USE IS GIVEN. RECOMMENDATIONS FOR FURTHER IMPLEMENTATION OF THE FIELD TESTING PROGRAM ARE ALSO PROVIDED.
