This research aimed to assess natural radioactivity levels in lake sediment of Karacaören II Dam. In this study sediment samples were collected from 12 station of lake in May, 2016. The natural radionuclides ²²⁶Ra, ²³²Th and ⁴⁰K were measured with a coaxial HPGe detector (Canberra, GC 1519 model) of 15% relative efficiency and a resolution of 1.9 keV at the 1332 keV gamma of ⁶⁰Co. In order to assess the radiological hazards resulting from natural radioactivity, radium equivalent activities (Ra_eq), absorber dose rate (D), internal (H_in) and external (H_ex) hazard index, annual effective dose rate (AED) and Excess life time cancer risk (ELCR) were calculated and compared with recommended values of international organizations.
