Moderate  to high winds can spread radioactive fallout across hundreds of square kilometers.

中到强风可以将放射性沉降物散布到数百平方公里的范围内。

Meanwhile, radioactive fallout spreads across  the Northeastern United States, causing another wave of hospitalizations.

与此同时， 放射性沉降物蔓延到美国东北部，引发另一波住院治疗。

On top of that, we'll be leaving long-lasting synthetic molecules from radioactive fallout, steroids, and all the plastic we dump in the ocean.

除此之外，我们将会留下长期留存的合成分子，它们源自放射性尘埃类固醇以及我们扔进海洋里的所有塑料。

Some people directly exposed  to radioactive fallout may not develop symptoms until days or months after the initial  explosion.

有些直接暴露于放射性尘埃的人可能要到初次爆炸后数天或数月才会出现症状。

While an American study failed to come up with any radioactive fallout that would have been produced by such an explosion, an Australian study did.

美国的一项研究没有发现这样的爆炸会产生任何放射性沉降物，但澳大利亚的一项研究发现了。

However, other devices such as a cobalt bomb can be detonated high up in the air and produce tremendous amounts of radioactive fallout.

然而，钴炸弹等其他装置可以在高空引爆并产生大量放射性沉降物。

Even if you just detonated one, the radioactive fallout would be an additional severe problem that would get carried by the trade winds and cause horrible environmental damage.

即使你只引爆了一个，放射性沉降物也会是一个额外的严重问题，它会被信风携带，造成可怕的环境破坏。
