| Summary: The average K, U and Th values for Sarıçiçek granodiorite are 2.98%, 3.15 ppm, 12.45 ppm and Sarıhan granodiorite are 1.83%, 2.73 ppm, 13.6 ppm, respectively. The granitic plutons have higher radioactivity than their surrounding formations, which are composed of basaltic, sedimantery or ultramafic rocks. Based on the concentrations of K, U, Th and their ratios, it is concluded that granitic rocks exposed in both area are formed as a mixture of the upper mantle and crustal materials. The average heat production for Sarıçiçek and Sarıhan granodiorites are estimated as 1.9 μWm−3 and 2.03 μWm−3, which are closer to the upper continental crustal value. In each studied area, different susceptibility variations are related to the rock and mineral types, exist in those areas. The boundary between plutons and surrounding formations are markedly revealed by the susceptibility variations. According to calculated radiological hazard parameters, there is no significant radiologic hazards for humans and environment in and around studied areas.
