قياس تراكيز اليورانيوم في تربة بعض مناطق محافظة ميسان العراق

الملخص EN

Concentrations of uranium were measured in this study for twenty soil samples from four areas with different depths (soil surface-20-40-60-80)cm .The study regions include Missan Governorate (Al-Iskan area,Al-Shibbana area ,Hai-Al Moualimin Al Jadied area ,Sector 30 area).

The Uranium concentrations in soil samples measured by using fission tracks registration in (CR-39) track detector that caused by the bombardment of (U-283) with thermal neutrons from (241Am-Be) neutron source that has flux neutron thermal of (5 ×103 n cm -2 s -1 ).

The concentrations values were calculated by a comparison with standard samples.

Through out the result, it was found that averages of uranium concentrations in soil samples were as the following : Al - Iskan area (٢.٧٦٥ ± ٠.٤٠٤) ppm, Al - Shibbana area (١.٧١٩ ± ٠.٤٣٢) ppm, Hai - Al - Moualimin Al - Jadied (٢.٣٢٠ ± ٠.٢٣٦) ppm, Sector 30 area (2.158±0.631) ppm.
