Janie, we're still looking for a mountain to bury the waste under, that in it's self is enough a cost factor to make it not a cost effective choice. I'd still want to be safe rather than sorry, maybe we don't know enough but I'd still stay with being cautious. My own take is that it's a danger not to be taken lightly. As long as it's manufactured the energy company/government can extort it's public, if it's from wind, sun, waves, tidal current, water flowing or pigs farting they will lose money & power & that's not gonna happen if they can help it.
