新的原子弹研究改变了辐射估计。

根据加州的劳伦斯利弗莫尔武器实验室和田纳西州的橡树岭国家实验室正在进行的新研究，一些关于核辐射对人类影响的最重要数据可能是错误的。正如这项工作的一位顾问所说，新的发现远不受欢迎，因为所有的修订都在朝着错误的方向发展--这一方向将使核能的倡导者感到担忧。政府物理学家重新计算了广岛和长崎原子弹爆炸产生的辐射场数据，得出了一些意想不到的结果。他们的统计数据显示，这些炸弹造成的大多数癌症来自低LET伽马射线，这表明这种常见类型的辐射比以前假设的更危险。
Some of the most important data on the effects of nuclear radiation on humans may be wrong, according to new research being done at the Lawrence Livermore Weapons Laboratory in California and the Oak Ridge National Laboratory in Tennessee. The new findings are far from welcome, as one consultant in this work says, for all the revisions are moving in the wrong direction - a direction that will worry the advocates of nuclear power. Government physicists have recalculated the data on the radiation fields created by the atomic blasts at Hiroshima and Nagasaki and produced some unexpected results. Their statistics show that most of the cancer caused by those bombs came from low LET gamma rays, suggesting that this common type of radiation is more hazardous than had been assumed before.
