Health risk assessment for personnels in downwind when DU hit tanks

In order to assess the health risk for soldiers in the use of depleted uranium(DU) in war,based on the test data of US army,parameters of the aerosol such as conversion fraction,composition,chemical characteristics,etc.produced when the tank was hit by DU penetrator were analyzed. The explosion-cloud method and Hotspot software were adopted to calculate the personnel′s DU exposure and inhalation doses in the downwind when the tank was hit by large caliber DU penetrator.The metabolic rule of DU in human body was analyzed by Biokmod software.The result shows that personal exposure dose E(τ) under this condition was less than 0.136 mSv.The risk of excess carcinogenic for lifetime was less than 6.8×10-6 and the risk of excess lethiferous carcinogenic for lifetime was less than 6.4×10-6.This health risk level may be accepted.
