Measurement of Radioactivity Pollution of dusty storms in middle and west parts of Iraq at 2007 and 2008

In this study Uranium concentration average absorbed dose and average external effective dose were calculated for dusty storm at 8/9/2007 and 27/4/2008 for some middle and west parts in Iraq. The result for specific activity of uranium was in range of (4.44-10.409 Bq/kg) and the absorbed dose range (1.904-4.465 nGy/h) for dusty storm at 8/9/2007 and the average spective activity (6.475-22.680 Bq/kg) and the average absorbed dose (2.777-9.729 nGy/h) for dusty storm 17/4/2008. All the results were lower than allow was level, but the a culmination of the dose of more then one dusty storm may have a damage effect
