In this study, the level of natural and artificial radioactivity in soil samples collected from the central region of Karaman was measured. Activity concentrations of the concerned radionuclides were determined by the technique of gamma ray spectrometry using HPGe detector. The obtained results of 238U-series (226Ra, 214Pb, 214Bi), 232Th-series (228Ac, 208Tl), 40K and fission product 137Cs are discussed. In order to evaulate the radiological hazard of the natural and artificial radioactivity in samples, the radium equivalent activity (Raeq ), the absorbed dose rate

(D), the annual effective dose and the external hazard index (Hex ) have been calculated. The

present data were compared with data obtained from different areas in Turkey.
