Diatomaceous earth is of sedimentary origin consists mainly of accumulated skeletons formed as a protective covering of the diatoms. Usually, high absorption capacity of diatomaceous earth provides its wide use as heat insulation, filter and absorbent material. Starting raw material diatomaceous earth from surface coal mine Kolubara, Serbia, was characterized using, scanning electron microscopy (SEM), X-ray diffraction (XRD). Chemical composition of diatomaceous earth was determined by wet chemical methods. In addition, the absorbed gamma ray dose rates is estimated based on the measured activity concentrations of natural radionuclides in clay were determined by gamma spectrometry. This research shows that this material is environmentally safe for further use.
