Introduction: Background: Twenty years ago Institute of Occupational Medicine in Sosnowiec put into practice an X-ray powder method (DSH) for qualitative analysis of asbestos in bulk samples. This method allows for precise determination of asbestos presence.
Purpose: Exploring DSH method for identification of asbestos by examination of a sample of inorganic mate-rial for industrial use.
Material and Methods: Asbestos is the most important material for technological applications due to its flexible and tensile fibers and its chemical resistance. The determination of types of asbestos are based on the crystalline structure. A diffraction pattern is uniquely characteristic for each type. Detection of asbestos in bulk insulation samples required special preparation of samples and step-scanning analysis. XRD scans of analyzed material were compared with standard reference powder diffraction patterns of asbestos.
Conclusions: Bulk insulate sample was layered. Chrysotile, amosite and crocidolite was determined in separated layers. Asbestos was not detected in one of the layers.
