> Sidenote, I'm sometimes a little befuddled that we would be afraid of putting radioactive material in the ground. The ground is already full of the stuff, and we don't spend much time worrying about an earthquake spitting up a boulder of yellow cake in our backyards. Ok, the concentration is different, but sometimes it seems like worrying about putting salt in the oceans. Not only is the concentration different, but also the composition. I haven't heard of plutonium occurring in nature.
