Any question answered...

you should DEFINITELY watch 'into eternity'. it's a documentary about nuclear waste and it's horrifying but way interesting. they cant put it anywhere tectonically/geologically active cos the stuff lasts for fucking millions of years and it would move around and come up to the surface etc. but they do put it underground - or at least when they have finished building the stores they will - but it has to go miles and miles and miles underground and it is a pretty difficult process! anyway watch the movie it's amazing

And the government have us believe it's Iran we need to worry about :D
