摘要

X-ray techniques, just as many other analytical methods, have been used in forensic science for several decades. The main applications of X-rays in the UK Forensic Science Service are in X-ray powder diffraction (XRD), X-ray fluorescence (XRF), and X-radiography. The complementary techniques of XRD and XRF are used mainly in trace analysis. Traces may consist of drugs, paint flakes, glass fragments, hair and fibres (natural and man-made), slivers of metal, soils, building materials, stains of any description, corrosion products, and loose powdered materials. X-radiography has a role in the examination of a wide variety of objects, from thin, low density objects such as documents using soft X-rays, to more dense objects using harder X-rays. This paper illustrates the use of XRD and X-radiography in four case studies. The first concerns XRD analysis of street seizure drugs and their excipients, and the second the attempted theft of a ship’s propeller. The two radiography cases involve (a) the use of soft X-rays for counterfeit banknote examination, and (b) hard X-rays for automobile tyre examination.
