A ground radiometric study of uranium, thorium and potassium in Isparta, Turkey

Abstract

The radioelement concentrations of uranium (238U), thorium (232Th) and potassium (40K), as their radionuclides eU, eTh and K, of Cünür Hill in the city of Isparta (Turkey) and its surroundings were measured using gamma-ray spectrometry with a NaI(Tl) detector. The measurements were performed over an area of 2 km × 8 km around Cünür Hill, which forms part of the Isparta volcanic region that has a trachyandesitic composition,and which included the limestone outcrops east of Cünür. The results are mapped as combined radioelement concentrations. The radioelementconcentrations of eU, eTh and K measured for Cünür Hill are high because of its trachyandesitic composition, while those measured in the limestone area were low, as would be expected. © 2010 by the Istituto Nazionale di Geofisica e Vulcanologia.
