Uranium is 1 1/2 times as dense as lead and is the heaviest naturally occurring metal. According to a 1983 McDonnell Douglas Customer Service First Quarter publication, only "depleted" uranium is used, which means it has been processed to remove most of its uranium 235, the most highly radioactive form used in nuclear powerplants. The remaining uranium 238 emits only low-level alpha radiation. While the depleted uranium normally poses no danger, it is to be handled with caution. The main hazard associated with depleted uranium is the harmful effect the material could have if it enters the body. If particles are inhaled or digested, they can be chemically toxic and cause a significant and long-lasting irradiation of internal tissue. Depleted uranium is slightly radioactive. To minimize radiation hazards, depleted uranium balance weights are 100 percent cadmium plated during the manufacturing process. If the cadmium plating is intact, normal handling of the parts is considered to be non-hazardous and no special precautions are recommended. The use of radioactive materials in many every day applications is not at all unusual. For example, tritium, a radioactive form of hydrogen, is used in self-luminous signs, such as exit signs, and watches. Thorium, which has a radiation activity level comparable to depleted uranium, is used in making gas mantels for lanterns, electronic equipment, and high-quality optical lenses for cameras and overhead projectors. Also, smoke detectors contain americium 241, a radioactive material. On arrival at accident scenes of aircraft suspected of containing balance weights made of depleted uranium, determine if balance weights have been damaged or lost their cadmium plating coating. Request specialized assistance if balance weights have been damaged or lost their cadmium plating. No penetration of the plating is allowed. <br><b>References : </b><br>A&P/IA Aviation Author http://www.stacheair.com For many years, aircraft manufacturers have used "depleted" uranium to balance ailerons, rudders, and elevators on certain jet aircraft and rotor blades on certain helicopters.

Even normal uranium isn't terribly radioactive, and depleted uranium is much less so.
