Evaluation of Environmental Gamma Radiation Dose around Bitlis Stream, Bitlis
Abstract
This investigation involved measuring gamma radiation rates at 20 distinct locations along Bitlis Stream utilizing a portable scintillation detector equipped with NaI(Tl) crystals. Alongside gamma dose rates (GDR), the annual effective dose equivalent (AED) and Excess lifetime cancer risk (ELCR) values were also calculated. The results are presented using well-structured graphs and tables for clarity and easy comparison. The mean values estimated at 1 meter above ground level for GDR, AED and ELCR were obtained as 0.112 μSv/h, 0.196 mSv/y and 0.784, respectively. These results show that GDR, AED, and ELCR measured in the study area exceed the global average limit values recommended by international health organizations. Furthermore, the findings were compared with several investigations undertaken in diverse parts of Türkiye in terms of radiological significance.
