in situ XRF; non-destructive analysis
The preservation and conservation of our cultural heritage has become one of the main concerns today all over the. world. In particular there is an increasing need for non-destructive investigations, as sampling from the unique and precious objects of art and archaeology. In addition to the conventional analytical procedures, techniques utilising nuclear instruments and methods play increasing role in this field. The small, portable X-ray fluorescence (XRF) spectrometers using radioisotope excitation allow in situ analysis in museums, galleries; or even on field. This paper presents illustrative applications of our XRF devices with radioisotope excitation. The detection of the presence of titanium in white spots of a painting provided scientific basis to decide that the painting in question was a fake. The difficulties caused by the simultaneous presence of Ti and Ba (a very frequent component white paints) are also discussed. (C) 2004 Elsevier B.V. All rights reserved.
