An x-ray micro-digital radiography (μ-DR) system has been developed at the Gadjah Mada University Indonesia. The μ- DR system was developed as an add-on unit on an x-ray Diffraction (XRD) system using one extra beam-port as its radiation source. A fluorescence screen encapsulated in a dark tube then coupled by a CCD camera was used as an imaging plate. The radiography objects were some sample clays for earthen or ceramic material of handicraft. The clays differ by particle size, namely: 40 mesh, 60 mesh, 80 mesh, and 100 mesh. The objects were put in front of the imaging plate and then they were exposed by x-ray beam. The image formed on the screen was captured by the CCD camera and then it was converted into digital microradiograph of a size of 720x576. Then, after noise suppression process and normalization procedure, the microradiograph were compared each other by considering particle size. This facility can be used as a non-destructive and testing material studies for examining the quality of earthen or ceramic handicraft.
