美国历来以别国作为新型武器的实战试验场,这已是不争的事实。二战时期试用原子弹是这样,冷战结束后,世界局势趋于缓和时期也是这样。在海湾战争中,伊拉克成了贫铀弹试验场。今年以美国力首的北约对南联盟狂轰滥炸78天,又投掷了大量的贫铀弹,于是美丽的南联盟又变成了美国新型次放射性武器的试验场,塞族人、阿族人谁都未能幸免试验场中“小白鼠”的命运,他们的家园成了放射性灾难的牺牲品。铀是具有放射性的银白色的金属,化学性质很活泼。有铀234、铀235、铀238三种同位素存在于铀矿中,在有些稀士矿石中也有少量存在。铀矿经提了炼可获得核燃料铀235,提炼后的副产品是铀238。铀238半哀期为44.7亿年,与铀235相比,具有不很强的放射性,故称铀238为贫铀。贫铀弹是70年代开始研制的,以高密度、高强
It is an indisputable fact that the United States has always tried to use other countries as a practical test ground for new types of weapons. This was the case with the experimental atomic bomb during the World War II, as was the case during the period when the world situation tended to ease after the end of the cold war. During the Gulf War, Iraq became a test-bed for depleting uranium. This year the U.S.-led NATO bombed the FRY for 78 days and threw a large number of depleted uranium bombs. As a result, the beautiful Yugoslav federation has become the test ground for a new type of U.S. secondary radiological weapons. Serbs and Albanians have not made any progress Can spared the fate of “mice” in the test field, and their homeland has become a victim of a radioactive disaster. Uranium is a radioactive silver-white metal, chemically very active. Uranium 234, uranium 235, uranium 238 three isotopes exist in uranium ore, in some rare ore there is also a small amount. Uranium ore refinery to obtain nuclear fuel uranium 235, the by-product of the extraction of uranium 238. Uranium 238 Halfmoon period of 4.47 billion years, compared with uranium 235, has a very strong radioactive, so called uranium 238 for depleted uranium. Depleted uranium bomb was developed in the 70’s to high-density, high strength
