What will we do with radioactive waste? The stuff is dangerous, so we bury it. But mere burial is not enough, since the earth moves, and someday, someone may actually dig that stuff up. In Finland, an island is being prepared to bury nuclear waste very, very deep, to keep it safely away from us. Tom Scott visited Onkalo, on the isle of Olkiluoto, to show us.
Tom refers to a 1993 report about marking nuclear waste sites. You can read some of the ideas generated here.
