处理核废料的最佳办法是什么?
And is it true that scientists have considered sending it into space?
科学家们真的曾动过将这些废料送往太空的念头吗?
Good question.
问的好。
To answer the second part first-yes,sending nuclear waste into space has come up.
为了回答，首先下半句的确属实，的确曾想到过向太空发射核废料。
But if a rocket or space shuttle carrying nuclear waste exploded, the radioactive material would spread far and wide.
但如果运送核废料火箭或航天飞机发生爆炸,那放射性物质会到处传播。
So it's too dangerous.
这样未免太过危险。
There have been a few other interesting ideas-such as burying nuclear waste beneath the ocean floor.
而还有一些其他有趣的想法，比如将核废料埋在海底深处。
Scientists have also thought about putting waste in really deep holes, burying it in polar ice sheets, and stashing it beneath uninhabited islands.
科学家也想过把垃圾埋在深深的洞穴中及极地冰盖中,并且想过送往无人居住的岛屿。
