Determination the concentration of heavy elements and gross alpha, beta, and gamma activities in soil samples from Tworeach district at Karbala governorate

الخلاصة

In this study, the radiological efficacy of selected samples of a hole produced by a rocket dropped during military operations in the second Gulf battle was measured. Since the fall of the rocket in 1991 on district of Tuwayrej, Karbala at central Iraq until this moment, there have been many miscarriages in women as well as cases of congenital malformation in children. For these reasons and in response to the appeals of the residents of the region, we conducted this study. Twelve different samples of soil were collected for the study area from different distances (0, 25, 50 and 100 m) and with different directions (North, South, East and West) from the edge of the hole. chemical method to calculate the percentage elements (Na, Cr, Ni, Ca, Fe, K, and Mg), in this samples, and using physical method to calculate the concentration of the natural radioactivity in the same samples the instrumentations used to count the gross alpha, beta, activities was alpha/beta proportional counter and High purity Germanium detector to calculate the gross gamma activity to count the radiation from these samples. The obtained results show that the gross alpha, beta and gamma activities ranged from (2.15 to 36.23Bq/Kg), (37.37 to 217.17Bq/Kg) and (2.26 to 50.92 Bq/Kg) respectively. In comparing the practical results with the global calculated results, the radiation levels of the studied models were found to be within permissible limits. © Published under licence by IOP Publishing Ltd.
