Assessment of natural radionuclide's in sediments of darbandikhan lake water resources at Kurdistan region-northeastern of Iraq

الملخص EN

A total of 25 of sediment samples were collected from Darbandikhan Lake and its different resources (spring, stream, and lake) during the summer season.

The activity concentration of primordial radionuclides and the concentration of major elements were found using Energy Dispersive X-ray fluorescence (EDXRF) techniques.

The average specific activity of 40K was found to be 202.27 Bq/kg, while the activity concentration for both uranium and thorium was beyond the detection limits.

Statistics of multivariate analysis were applied to sediment samples, which shows that there is a strong positive correlation coefficient between 40K and Ti, Mn and Fe and a weak negative correlation between 40K and Mg, Si, P, Ca was observed
