By Dave LindorffThe Nuclear Regulator Commission is considering an application by the US Army for a permit to have depleted uranium at its Pohakuloa Training Area, a vast stretch of flat land in what's called the "saddle" between the sacred mountains of Mauna Loa and Mauna Kea on Hawaii's Big Island, and at the Schofield Barracks on the island of Oahu. In fact, what the Army is asking for is a permit to leave in place the DU left over from years of test firing of M101 mortar "spotting rounds," that each contained close to half a pound of depleted uranium (DU). The Army, which originally denied that any DU weapons had been used at either location, now says that as many as 2000 rounds of M101 DU mortars might have been fired at Pohakuloa alone.
The Army is actually seeking a master permit from the NRC to cover all the sites where it has fired DU weapons, including penetrator shells that, unlike the M101, are designed to hit targets and burn on impact, turning the DU in the warhead into a fine dust of uranium oxide. Hearings on this proposal were held in Hawaii on Aug. 26 and 27.

An application for a 99-year permit to test DU weapons at the NM Inst. Of Mining and Technology claimed that that site's test area was "so contaminated with DU"as to preclude any other use"!
DU weapons have also been used by the Navy at Vieques Island off Puerto Rico (the Navy claimed it was a "mistake."
The Pentagon continues a long history of claiming that DU--which is the uranium that is left after the fissionable isotope U-235 is removed to make nuclear fuel and bombs--is not dangerous, although this official stance is belied by the warnings it has given to its troops (though not to civilians in battle zones), to stay well clear of tanks and other equipment destroyed by US tanks, which used DU weapons as the ordnance of choice in both the Gulf War and the current Iraq War. During both wars, DU ammunition was used by Army and Marine tanks, by the Bradley Fighting Vehicle, the A-10 ground support jet, the Marine Harrier jet, and specially equipped F16 fighter jets. The Navy also switched from DU ammunition to tungsten ammunition in its Phalanx anti-missile ship defense system because of health and environmental concerns with the DU ammo.
The Pentagon denies that it uses depleted uranium in bombs, missiles and cruise missile warheads, but military personnel have reported their use in all three delivery systems, and reports exist of DU bunker-buster bombs, DU-tipped penetrator warheads on Tomahawk cruise missiles and on some air-to-ground missiles.
It's a good bet that all US munitions containing DU have been widely tested at various US military bases and testing grounds.
