【英语时差8,16】处置核废弃物-上

What’s the best way to dispose¹ of nuclear waste? And is it true that scientists have considered sending it into space? Good question. To answer the second part first–yes, sending nuclear waste into space has come up. But if a rocket or space shuttle carrying nuclear waste exploded, the radioactive² material would spread far and wide. So it’s too dangerous. There have been a few other interesting ideas–such as burying nuclear waste beneath the ocean floor. Scientists have also thought about putting waste in really deep holes, burying it in polar³ ice sheets, and stashing⁴ it beneath uninhabited islands.
