Abstract

The aim of this study is to determine the level of natural radioactivity occured by

radionuclides, 226_Ra, 232_{Th and} 40_{K, in soil samples collected from some villages in}

Mersin, Turkey. The mean activity concentrations of 226_Ra, 232_{Th and} 40_{K are measured}

over all collected soil samples as 19.96 ± 2.34 Bq/kg, 42.8 ± 3.28 Bq/kg and 388.68 ± 5.26 Bq/kg, respectively using gamma ray spectroscopy by HPGe dedector. It was observed that these activity concentrations are mostly in agreement with the world

activity averages of 35, 30 and 400 Bq/kg for 238_U, 232_{Th and} 40_{K, respectively, indicated}

in UNSCEAR 2008 report. Mean 232_{Th activity was achieved a bit higher than the}

avarage. However, the average annual effective dose equivalent was calculated as 0.062 mSv/y and found to be lower than the worldwide avarage value of 0.063 mSv/y.

Keywords: Natural radioactivity, Soil samples, Annual effective dose equivalent.
