ABSTRACT
Background: depleted uranium [DU], which is one of the residues of enriched uranium, has military and nonmilitary usage. Effects of DU on environment depend on chemical composition of the soil and the rocks. Bullets fallen in the joining part of sand and quartz will erode faster and pollute the superficial waters. This article discusses production and usage of DU and its environmental effects and the means to decontaminate the environment
Methods and materials: this study was a review article. Data and information were collected from libraries and Internet. Search word were, depleted uranium, environmental impact, natural resources in Rose net and google from 1997-2005. Search provided us with 20 full text articles
Results: high percentage [50-96%] of suspended particles of Uranium Oxide that is produced when DU hits the aims are inhale able. Approximately, 52 83% of these particles are insoluble in pulmonary fluids. Particles with the size of 5 micron or lesser can enter the body via air or food. DU particles may contaminate air, water or soil and stay there till it is moved to contaminate other areas
Conclusions: suggested means to reduce contaminations are annual sampling of water resources, environmental decontamination, public awareness, political support of the involved countries, active participation of the responsible organizations, putting sanction on production of these weapons
