Determination and mapping of activity levels of 40K in Madloom region in al-Najaf al-Ashraf

الملخص EN

Ninety nine soil samples were collected from Madloom region in Al-Najaf Al-Ashraf.

The gamma rays spectral measurements were done for all samples by using Sodium Iodide activated by Thalium NaI (Tl), its dimension 2"× 2", from the spectral analysis identified Potassium 40K radionuclide.

The activity concentration was calculated for 40K, ranged from 66.53±1.39 Bq.Kg-1 to 225.32 ± 2.84 Bq.Kg-1, and the mean value were 142 ± 2.16 Bq.Kg-1.
