Uranium concentrations of human blood and soil samples have been studied at different ages and occupations in Babylon, Iraq. The technique of nuclear track detectors CR 39 with nuclear fission track analysis has been used to determine the uranium concentrations in this study. Results have shown that the concentrations of uranium ranged from 0.56 ± 0.06 to 1.24 ± 0.29 ppb with an average of 0.83 ± 0.18 ppb in blood samples. On the other hand, the concentrations of uranium in soil samples ranged from 0.93 ± 0.20 to 2.59 ± 0.15 ppm with an average of 1.72 ± 0.19 ppm. Moreover, the highest averages of concentration have been found in the city center of Babylon, reaching 1.09 ± 0.22 ppb and 2.10 ± 0.23 ppm in blood and soil samples, respectively. The results have further proved that gender and occupations have an effect in increasing the concentrations of uranium. In addition, the concentrations in blood samples are generally lower than the concentration in soil samples.

“…After the irradiation process, the CR-39 detectors were etched in NaOH solution with normality (N= 6.25) at temperature of 60 °C for 5 h. Olympus optical microscope with magnification of 400 × was used to record the induced fission tracks densities. The fission track densities were measured on the surfaces, showing uniform distribution of uranium samples, and were measured by comparison between the tracks density registered on CR-39 detectors around the samples pellet and that of standard samples pellet by using the following equation UX =UX(PX/PS) (18).…”

This study aimed to determine the concentration of depleted uranium and the main histopathological changes in local fish and chickens at a selected Iraqi area suspected to be polluted with uranium. Different locations of Al-Tuwaitha region (Southern of Baghdad) were surveyed randomly to collect a total of 15 samples from each animal species. The animals were sacrificed and dissected at the site of collection. Muscle samples were collected to determine uranium concentrations using nuclear fission track analysis with CR-39 detectors. For histopathological changes, sample tissues from fish (liver, gills, and kidney) and chickens (liver, kidney, and lung) were collected and fixed in 10% neutral buffered formalin. The results showed that there was a significant elevation in uranium concentration in both fish and chicken muscles (1.94±0.77 µg/Kg and 2.19±0.82 µg/Kg, respectively) compared with recommended uranium concentration. Histopathological examination showed several effects included congestion and thickening of blood vessels walls, vacuolation, necrosis, fibrosis and inflammatory cells infiltration in most tissue section of collected organs. In conclusion, the uranium residues that found in both fish and chicken meats could raise the concerns about consumption of both animal species that had been bred in Al-Tuwaitha, and could be an indicator of environmental pollution with uranium in this region.

“…Radiological and toxicological contaminants can cause cancerous disease and other changes in the health of humans and the living world in general, thus substantially influencing the changes in the environment (1)(2) . Uranium -heavy element, silver colour -is a radioactive natural element that is commonly distributed in the crust of the earth and it has both radioactive and toxic effects.…”

Background:The examination of the urine samples is the preferable procedure to observing the inner exposure to radioactive and toxic pollutants in human body. This study focuses on the uranium concentrations (UC) and toxic metal concentrations (TMC) in urine samples of cancer patients and healthy volunteers from Al-Diwaniyah governorate. Materials and Methods: Fission track technique with CR -39 track detectors and atomic absorption spectrophotometry were used to determine the uranium and toxic metals, respectively. Results: For the patients group the result of UC ranged between 5.04 μg /l to 2.21 μg/l, with the average value was 3.83 μg/l, while the data of UC of the healthy group varied from 3.15 μg/l to 0.49 μg/l, with the average value was 1.91 μg/l. The average values of TMC (Pb, Ni and Cd) in urine samples of cancer patients were 0.342 mg/l, 0.231 mg/l, and 0.075 mg/l respectively, whereas the average values of corresponding elements in urine samples of healthy subjects were 0.233 mg/ l, 0.127 mg/l, and 0.025 mg/l, respectively. Conclusion: The current in vitro investigation shows the pollution in urine samples of the participants through UC and TMC and also finds that the UC and TMC in urine of cancer patients significantly higher than healthy volunteers. The results of (UC) and (TMC) in urine samples of the participants exceeded the recommended limits.
