A REEVALUATION AND MODIFICATION OF RADIOCHEMICAL AND INSTRUMENTAL TECHNIQUES ORDINARILY USED IN FIREARM DISCHARGE RESIDUE DETECTION.

Abstract

THE MODIFIED TECHNIQUE INVOLVES THE USE OF BARIUM AND ANTIMONY TRACERS WHICH ARE USED AS INTERNAL STANDARDS AND THE COPRECIPITATION OF ANTIMONY TRISULFIDE AND BARIUM SULFATE. THIS PROCEDURE REDUCES THE MANIPULATIONS OF RADIOACTIVE SUBSTANCES AND INCREASES THE RELIABILITY OF THE RESULTS. DETAILS AND PITFALLS ARE POINTED OUT FOR THE BENEFIT OF THE NOVICE WORKER PLANNING TO ACQUIRE NEUTRON ACTIVATION ANALYSIS CAPABILITY. (AUTHOR ABSTRACT MODIFIED)
