1 ,, X HandyType XRay Fluorescence Element Analyzer Jun Kawai Department of Materials Science and Engineering, Kyoto University Handy Xray fluorescence (XRF) spectrometers are reviewed. A brief history of development, comparison with desk top or larger XRF spectrometers, and analyzed data examples are described. The usages of handy spectrometers related to recycling of metal scrap, control of hazardous elements in industrial products, toxic element analysis of soil at the trading of immovables, and developing a mine of rare metals, are discussed. The total number of portable XRF has been over all aver the world at the stage of year Key words : Xray fluorescence analysis, XRF, handy, portable, spectrometer, EDX, EDS 2000 X (XRF, Xray fluorescence) X X X 2 X ( X ) 1)3) X ( ) X X X X CSI ( ) XRF ( ) ) 4) X 5) X 1 kw X W X X (Sakyo-ku, Kyoto, Japan) RoHSrestriction of the use of certain hazardous substances in electrical and electronic equipment WEEE (waste electrical and electronic equipment)elv (end of life vehicles ) 6), 7) ( ) As, Pb, Hg, 6 Cr, Cd, Br () JIS
