| Popis: | In 1990, a program was initiated to cover Slovenia with portable gamma-ray spectrometer measurements on a 5 x 5 km grid. The measurements were performed with a four channel Scintrex GAD-6 spectrometer. Five gamma-ray measurements were taken at each of 816 locations. Samples of the upper 10 cm of soil profile were collected for laboratory analysis. Uranium in samples was determinedby delayed neutron method (DNC). Other 35 elements: Ag, Al, As, Au, Ba, Be,Bi, Ca, Co, Cr, Cu, Fe, K, La, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Sb, Se, Sn, Sr, Th, Ti,U, V, W, Y, Zn and Zr were analyzed by plasma-coupled emission spectrometry (ICP). The field gamma-ray measurements were converted to ground concentrationsof potassium, uranium and thorium. These show good correlation with the laboratory analyses of soil samples. Regardless of the wide spaced sampling, the produced maps show relatively good correlation with main geological units. They demonstrated that the methodology can be successfully implemented for environmental monitoring, geological mapping and mineral exploration. The product ofthis project is the frist natural background radioactivity map of Slovenia covering the entire country. |
