Abstract
In this study, the CR-39 detector technique was used, to estimate the uranium concentration from the soil in midland refineries Company (Doura refine (, Baghdad, Iraq. Uranium concentrations in soil samples have been measured using solid state nuclear track detector type CR-39. Nine soil samples were collected from different areas within the Doura refinery and other soil samples were collected form Abu Tayara Street and ALshortaa District outside the refinery for comparison. The results showed variable values for uranium concentrations. The average value of uranium concentration was found to be 0.37 ppm in doura refinery. For areas outside the refinery, the concentration of uranium was 0.008 ppm. These results were less than the global limit.
Highlights
Some human activities may result in an increase in the exposures and need to be controlled by regulations
Proved that uranium can diffuse into soil with 15cm for 8 years
Uranium concentration (UC) was measured for 3-10 cm depths of soil samples collected from 11 districts. (Each sample represent the average value of three samples were taken from the site)
Summary
Some human activities may result in an increase in the exposures and need to be controlled by regulations. In this context, materials that are giving rise to the increased radiation exposures are known by the Naturally Occurring Radioactive Material (NORM). Long-lived radioactive elements include uranium, thorium and potassium and any of their decay products, such as radium and radon [1, 2, 3]. These elements exist in the Earth's crust, atmosphere and concentrated at certain places such as uranium ore bodies. The calculable health risks from exposure to low levels of 226Ra and 238U are little, and short term exposures cause solely very little risks [4, 5]
