A study on the activity concentrations of ²²⁶Ra, ²³²Th, ⁴⁰K, ¹³⁷Cs and radiological risk assessments in soil samples from Seydisehir and Beysehir districts of Konya in Turkey

The aim of this study is to investigate the activity concentrations of ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs in soil samples from Seydisehir and Beysehir districts of Konya province in Turkey using gamma-ray spectrometry and to calculate radiological risk parameters. The average radioactivity concentrations of ²²⁶Ra and ²³²Th are higher than world average value whereas the average radioactivity concentration of ⁴⁰K is lower than world average value. Mean values of absorbed gamma dose rate and annual effective dose equivalent are higher than world mean value while mean value of radium equivalent activity is lower than world average value. (author)
