Abstract

In this work the radiation level were measured and the type and the amount of radioactive materials are determined in water of Tiger river for some selected regions in Salahddin Governorate. The study stations were chosen for some regions along the Tiger river flow that are characterized with relatively high pollution are: Al-Sharaqt, Al-Senia, Al-Alam, Samraa, Al-Dhloaya and Balid. Measurements of radiation level were made in (49) stations and other controlling samples of distilled water using the method of track detectors. The study had two directions; the first is a field work, where the dosimeters were placed in the chosen stations, and the other is a laboratory work where the samples were brought from the same stations to the laboratory and measured. The results show that the highest radiation level measured by CR-39 is 3.16 µrad . Moreover, the study shows that the radiation level in the measured water of Tigers river in Salahadin Governorate is within the internationally permissible limit which is 8.9 µrad/h, despite the slight increase in the concentration of radioactive materials for the studies performed the eighties of last century, where the increase is attributed to the conditions of the studied regions in the period. The results had also revealed the existence of the low radioactivity in some samples of water as compared with the internationally permissible limits according to the recommendations of UNSCEAR .
