The Fine Art of Fraud - The Detection of Forgery with Scientific Tools

Dr. Christian Segebade

This presentation describes the use of different scientific methods including physics, chemistry (radiochemistry in particular), radiography and computer-aided tomography (CT), metallography and others for the detection of various kinds of forgery of e.g. antiques, paintings, documents, money and more. Radioanalytical tools like accelerator-based photon activation analysis and X-ray fluorescence spectrometry are moved into focus. Nearly all methods involved work strictly non-destructively; some, e.g. microhardness measurement, leave negligible injury in the material of the respective objects.
