Quantitative Element Anaysis of Samples from Mine Region near Buhovo, Bulgaria

The elemental composition of samples of soil from the ground near the uranium mines Buhovo and waste material resulting from mining activities of uranium ore has been analyzed using X-ray fluorescence technique. Samples were taken from the meadow sites, from heaps of tailings from shafts and mines, located northeast of Sofia, between the cities of Buhovo and Seslavtsi at the southern slopes of Murgash part of the Balkan Range. The quantity of uranium in the samples as well as the quantities of other heavy elements has been analysed. A comparison between the measured composition of these elements and the corresponding gamma activity has been conducted. The quantity of some other important from the ecological point of view elements such as Sr, Mn, Ni, Zn, Cu, As, Pb и Ba, etc., has been studied.
