The concentration of natural radioactivity was determined in the surface soil of the Gözlek Thermal SPA in Amasya. The activity concentrations of natural radionuclides in soil samples were determined using gamma-ray spectrometer, containing a 3"× 3" NaI(Tl) detector connected to multi-channel-analyser. The photo-peaks at 1460, 1764 and 2615 keV are due to 40K, 226Ra and 232Th, respectively. The radiological hazard indices of the natural radionuclides content, radium equivalent activities Raeq, absorbed dose rate (ADR), annual effective dose rate (AEDR) and external hazard index Hex were also calculated.
