Abstract: In this research, the CR-39 detector technique was used, to estimate the radon concentration from the soil in Midland refineries Company Doura refinery, Baghdad, Iraq. Radon concentrations and Annual Effective Dose rate in soil samples have been measured by using solid state nuclear track detector type CR-39. Nine soil samples were collected from different areas within the Doura refinery and two soil samples were collected for areas outside the refinery for comparison. The results showed variable values for concentrations of radon gas and the effective dose rate.The average radon concentration were found to be 280.24 Bq/m3 and annual effective dose rate 7.07 mSv/y in Doura refinery. For areas outside the refinery, the concentration of radon were 154.96 Bq/m3. Annual effective dose rate 3.90 mSv/y. These results were higher than the global limit.
