The corrosion of depleted uranium in terrestrial and marine environments

► In-situ experiments were conducted to evaluate corrosion rates of depleted uranium. ► Samples were corroded in marine sediments, open sea water and two terrestrial soils. ► The depleted uranium titanium alloy corroded fastest in the marine environments. ► Rates of mass loss can vary through time if corrosion products are not removed. ► Laboratory measurements do not replicate the complexities of real environments.
