Dr. Loewenstein mentions that "large pieces of uranium oxidize rapidly in a long-lasting fire whenever they are heated in the air to a temperature of about 500 C".3 A report by the Amsterdam-based Laka Foundation, Documentation and Research Center on Nuclear Energy, informs: "The great danger from this chemical reaction is that the escaping cloud of dust with thousands of microparticles of uranium oxide can be inhaled or swallowed by bystanders. The American physicist Robert L. Parker wrote in Nature 4, in a worst-case scenario involving the crash of a Boeing 747, that about 250,000 people would run health risks (or near-poisoning) as a result of inhalation or swallowing of uranium oxide particles. Parker's conclusion assumed the presence of 450 kilos of DU in a Boeing 747. He says: "Extended tests by the American Navy and NASA showed that the temperature of the fireball in a plane crash can reach 1200 C. Such temperatures are high enough to cause very rapid oxidation of depleted uranium." 5
so the tempratures in the TW center was defntly hot enuff...
wonder how much DU they put in 757's
