Depleted Uranium Munitions Cause Tension Between Russia and the West.

The US National Security Council spokesman has suggested that Russian tanks can avoid the British depleted uranium munitions being sent to Ukraine by retreating back across the border. Depleted uranium rounds are 70% denser than lead, producing significantly more kinetic energy, and are particularly effective in piercing enemy armor. The use of depleted uranium rounds has been linked with long-term radiation remnants in affected areas, though it is less clear whether this radiation has adverse effects.
