Depleted uranium in the air during the cleanup operations at Cape Arza

Abstract

Cape Arza was contaminated with depleted uranium (DU) in the air strikes of NATO aeroplanes on May 30,1999. The cleanup and decontamination of the site started in 2001. Here the results of air monitoring performed during the cleanup operations in Spring 2002. are presented. The collected air samples were analyzed by high-resolution alpha spectrometry. The obtained concentrations of airborne uranium are about ten times higher than the average value usually reported for air. The ratio of the U-234/U-238 activities indicates the presence of depleted uranium in the air during the cleanup action, due to resuspension and soil disturbance in the contaminated teritory.
