长久以来,很多人都认为,只有高纯度的铀或钚才能够用来制造原子弹。然而《今日美国》3月3日刊登的一篇文章却称,使用低纯度核原料,甚至核废料制造的原子弹早在五年前就在美国试爆成功,其爆炸力可在瞬间摧毁一个数平方公里大的小城。尤其令五角大楼感到担心的是,低纯度核原料在国际武器交易黑市上唾手可得,如果被不法分子或组织利用,将贻害无穷。
For a long time, many people believed that only high-purity uranium or plutonium could be used to make atomic bombs. However, an article published in the “USA Today” on March 3 stated that the use of low-purity nuclear materials and even atomic bombs made of nuclear waste had been successfully tested in the United States as early as five years ago. Its explosive power could destroy a number in an instant. Square kilometers of small town. In particular, the Pentagon is concerned that low-grade nuclear materials are readily available on the black market of international weapons trading. If they are used by lawless elements or organizations, they will cause endless harm.
