N2 - This study assesses the level of background radiation for Kayseri province of Turkey. Natural radionuclide activity concentrations in soil samples were determined using high-resolution gamma spectroscopy. Outdoor gamma dose measurements in air at 1 m above ground level were determined using a portable gamma scintillation detector. The obtained results of uranium and thorium series as well as potassium ( 40K) are discussed. The present data were compared with the data obtained from different areas in Turkey. From the measured gamma-ray spectra, the average activity concentrations were determined for 238U (range from 3.91 to 794.25 Bq kg -1), 232Th (range from 0.68 to 245.55 Bq kg -1) and 40K (range from 23.68 to 2718.71 Bq kg -1). The average activity concentrations of 238U, 232Th and 40K were found to be 35.51, 37.27 and 429.66 Bq kg -1, respectively, and 11.53 Bq kg -1 for the fission product 137Cs. The highest values of 238U, 232Th and 40K concentrations (794.25 Bq kg -1, 245.55 Bq kg -1, 2718.71 Bq kg -1, respectively) were observed in abnormal samples at Hayriye village. The average outdoor gamma dose rate in air at 1 m above the ground was determined as 114.43 nGy h -1. Using the data obtained in this study, the average annual effective dose for a person living in Kayseri was found to be about 140.34 μSv.
