| Environmental radioactivity is measurable in the water and sediments of selected areas of the southern Iraq marshes and Main Drain River. Chemilum in essences technique is used for the calculation radiation dose for the selected samples of the study. Its value was (4.13 μ rad /h). Solid state track detectors method is used, the detector (CR- 39) after putting this detector in the waters of the selected stations. After making the track, it is compared to control samples. Then, radiation dose is calculated which is (4.13 μ rad / h). It is found that the results of both methods are too close to one another through the limited of the calculation wrongs. To measure the radioactivity of the sediments gamma spectroscopy system with sensitivity level (0.5 Bq/kg) is used. The results showed that no radiation pollution is there in the samples selected, although the area contains some war machines that are destroyed with depleted uranium in the second gulf war. This goes in line with other studies, showing in dissolution water of depleted uranium as for the radioactivity in sediment samples, it sensed 137Cs with level (26.35 Bq /kg.) and results of uranium 238 U. With depleted uranium in the second gulf war. These accords with the local and international studies concerning the dissolution of depleted uranium in water. for knowing the type of isotopes in the water of the natural marshes gamma spectroscopy is used, using sodium conter. it is found that the most important isotope Cs-137, which is one of the radioactive isotopes resulted from the nuclear weapone experiments on the surface of the earth and result of uranium U- 238. | ||
