Assessment of Uranium levels in workers urine samples for the Al-Kifl brick factories in Babil Governorate – Iraq

This study aimed to determine the levels of "uranium" in human urine from 72 samples taken in the Babil Governorate of Iraq. The maximum value of uranium concentration (4.171 ± 0.054 ppb) was reached in the urine samples of workers of Al-Kifl brick factories, according to the results obtained with CR-39. The lowest value of uranium concentration was (1.359 ± 0.017 ppb). The average uranium concentration in urine samples taken from employees of Al-Kifl brick factories was (2.81 ± 0.69 ppb). The control group's results indicated that the greatest uranium concentration was (1.429± 0.05 ppb), and the lowest uranium concentration was (0.215± 0.04 ppb). The control group's urine samples had an average uranium concentration of (0.81 ± 0.32 ppb). Ultimately, uranium concentrations were determined using a few parameters. It was discovered that uranium concentrations rise with increasing daily and cumulative working hours, rise in workers who smoke relative to those who do not, and rise with age.
