Abstract EN
The natural radioactivity existed since creation of the universe due to the long life time of some radionuclides.
This natural radioactivity is caused by γ-radiation originating from the uranium and thorium series and 40K.
In this study, the gamma radiation has been measured to determine natural radioactivity of 238U, 232Th, and 40K in collected sedimentary rock samples in different places of Turkey.
The measurements have been performed using γ-ray spectrometer containing NaI(Tl) detector and multichannel analyser (MCA).
Absorbed dose rate (D), annual effective dose (AED), radium equivalent activities ( Ra eq ), external hazard index ( H ex ), and internal hazard index ( H in ) associated with the natural radionuclide were calculated to assess the radiation hazard of the natural radioactivity in the sedimentary rock samples.
The average values of absorbed dose rate in air (D), annual effective dose (AED), radium equivalent activity ( Ra eq ), external hazard index ( H ex ), and internal hazard index ( H in ) were calculated and these were 45.425 nGy/h, 0.056 mSv/y, 99.014 Bq/kg, 0.267, and 0.361, respectively.
