What are some common uses for depleted uranium (DU)?

Depleted uranium (DU) has specific applications primarily due to its unique properties, which include high density and ability to penetrate armor effectively. One of the most notable uses of DU is in kinetic energy projectiles employed by military forces. These projectiles, often used in anti-tank shells, utilize DU's dense nature to enhance their capability to penetrate armored targets during combat.

Additionally, DU is utilized for radiation shielding. Given its density, it is effective in blocking various types of radiation, making it suitable for use in protective equipment and structures, particularly in military and industrial settings where radiation exposure is a concern.

The other options do not accurately reflect the actual applications of depleted uranium. Building construction and fuel storage, household items, agricultural equipment, water purification, and food preservation are unrelated to the recognized uses of DU, which are primarily military and specialized industrial applications.
