Calculation of Risk Indicators for Radioactivity in the Soil of Region Hammam Al-Alil, Nineveh Governorate, Iraq

Ten soil samples were collected from different areas on Hammam Al-Alil Township, located in the city of Mosul within the Nineveh Governorate / Iraq.The specific activity of natural radionuclides ( 238 U, 232 Th, 40 K and 137 Cs) were measured, and the results showed that the values of radioactivity concentration of the mentioned nuclides for soil samples ranged between (BDL, BDL, 3.52, BDL) Bq/ kg to (3.12, 6.05, 73.85, 2.02) Bq/ kg with an average (0.87, 3.13, 27.2 and 0.75) Bq/ kg, respectively, and the activity of the radium equivalent measured and its average value was (10.03)Bq/ kg.As well as absorbed dose in the air, which was the average value (3.42) nGy/ h.The average annual dose in the outside and inside were (0.004 mSv/y, 0.016 mSv/y) respectively, and the average internal and external hazard indicators were found, and its value was (0.02, 0.02) respectively.Finally, the lifetime risk of developing cancer was determined utilizing the risk factors for Ionizing radiation's biological effects are discussed by the International Committee on Radiation Protection.All values of soil samples are less than the global limit.
