There were big explosions, and radioactive gas went into the air.

发生大爆炸，放射性气体进入空气。

But if the radioactive gas pressure is too high, containment fails and the gasses escape into the air, spreading as far and wide as the wind blows.

但如果放射性气压太高，容器无法阻拦它， 那么放射性气体就会渗入空气，然后被风广泛散播。

At the bottom of the destroied reactor, 1200 tons of white-hot magma continue to burn at over 3000 degrees, sending liters of radioactive gas and dust into the atmosphere.

在毁坏的反应炉底部 1200吨的高热岩浆持续以3千度高温燃烧 对大气不断散发无数的放射性气体与尘埃。

This method allows any radioactive gases  to be absorbed and in the event of an emergency the reactor can be drained and  the salt solidified, preventing a meltdown.

这种方法可以吸收任何放射性气体，在紧急情况下可以排空反应堆，使盐固化，防止熔毁。
