Besides nuclear power plant fuel, U has numerous other military and civilian uses. Uranium and other radionuclides are used by nuclear medicine (MRIs, X-rays, radioisotope injections, radiation treatment, etc.), scientific research (age-dating materials, compositional information, metabolic studies, etc.), agriculture (irradiating food and seeds), consumer products (smoke detectors, watches, irradiating bandages and other items to sterilize them, computer components, etc), materials testing for numerous industries (automotive, aircraft, construction, mining and oil) and space exploration (fuels). In addition, depleted uranium (DU) has been used for counterweights in sail boat's keel, ballast in boats, pigments and radiation shielding.
Depleted uranium is used by the military for its armour piercing capabilities as penetrators, and highly enriched (>90% U-235) Uranium is used by the military for weapons.
