Radioactivity monitoring in drinking water of Zahedan, Iran

ABSTRACT

The present research has focused on the effect of radioactivity on drinking water from five sites in the region of Zahedan city. The measurement of water activity in wells, river and spring has been used as a screening method. The determination of gamma emitters was performed by use the application of gamma spectrometry. The values of Radium concentration was between less than 2 mBq/l to 3 +/- 0.4 for water wells, 5 +/- 0.4 mBq/L for river, and less than 2 mBq/L for spring. All values of activity in the selected water samples were lower than the permissible limit for drinking water consumption. The water was safe for drinking, washing and agricultural use
