Airborne depleted uranium particle dispersion and hazard from intake through inhalation

In this paper we present depleted uranium aerosols dispersion from cloud generating due DU munitions impact to hard target. For diffusion modeling it is used Gaussian puff trajectory model. It is shown that dispersion depend of meteorological conditions. Regardless to DU concentration distribution, the worst case scenarios for quantity of intake DU aerosols due inhalation was happened for bystanders that stay far from hit hard target: (1) about 250-550 m, during cloudy calm weather and (2) as far as 150 m, during clear sky about noon. Amount of intake of DU through inhalation, that is the most dangerous route of intake, can varied due to level of physical activity at one side and characteristics of aerosols and assumed meteorological scenario at the other.
