I hear there is something called the elephants foot that is where most of the radioactive material is. How much of the radioactive material is still left over? Are there a lot of it? How dangerous would it be to touch the elephants foot?
There is quite a bit left over. That's why some speculate the area could be contaminated for hundreds of more years. If we can't ever move it, the problem will be around forever. We can block it out with domes as much as we want, but it doesn't stop it forever.
