Measurement of uranium concentrations in soil samples of Al-Diwaniyah governorate, Iraq by using CR-39 track detector

Abbas A. Sweaf, Thaer M. Salman


The present work is concerned with the measurements of uranium concentrations in forty-nine surface soils samples from selected locations (some of them were measured for the first time as far as authors know) in Al-Diwaniyah governorate by using uranium fission fragment U-235 (n-f), obtained by the bombardment of U-235 with thermal neutrons. The results have shown that the highest uranium concentration in surface soils samples in the selected regions in Al-Diwaniyah governorate was found in  (Al-sdeer) region, which was equal to (8.86±0.89 ppm), while the lowest uranium concentration was found in  (Al-shamr  2) region which was equal to (2.50±0.92 ppm) The present results have show that the uranium concentrations in the studied surface soils samples were less than the allowed value (11.7 ppm) recommended by UNSCEAR, 1993.
