Evaluation of radiological parameters in the soil along the coastline of Arin Lake (Bitlis)

Abstract This investigation involved the assessment of natural (²³⁸U, ²³²Th, and ⁴⁰K) and artificial (¹³⁷Cs) radioactivity concentrations in 27 soil samples taken from the Arin Lake (Bitlis) coastline, using the HPGe detector system. For this purpose, dose calculations were performed on the basis of the activity concentration values of soil samples. The mean radioactivity concentration of ²²⁶Ra, ²³²Th, ⁴⁰K, and ¹³⁷Cs were 34.73, 32.43, 529.28, and 8.46 Bq/kg, respectively. The radiological parameters with Ra equivalent (Raeq) value, the annual effective dose and the absorbed dose values were lower than the recommended world mean. Furtermore, Radiological hazard indices, Hin, Hex, and ELCR, were obtained below specified limit values. In addition, the findings were compared to similar research in several other countries.
