1.The design of the reactor was such that it lacked a protective containment; once it exploded, radioactive debris was ejected into the air.
反应器的设计是酱紫的，由于它缺乏一个保护壳，所以一旦爆炸，放射性碎片会被喷射到空气中。
2.Radioactive debris was spread over a wide area.
放射性残骸散落广泛的区域。
3.Residents fled smack into the plume of air carrying radioactive debris.
他们直接逃进了空气中充斥着核碎片的地区。
4.The radioactive debris is produced when the core is exposed above the coolant water level and overheats.
当核心暴露于冷却水位以上并过热，那放射性碎片就会产生。
5.The radioactive debris from a nuclear explosion can be analysed to reveal information about the bomb, such as its fuel.
原子核爆炸后的放射性残骸被分解之后能够暴露有关炸弹的信息，例如它的燃料。
