By and large they are absorbed and turned into heat. Some rough numbers: 1 MeV gamma rays are 90% absorbed by 3 cm of lead. That same level of absorption requires about 4x the distance in granite, 6x the distance in concrete, and 9x the distance in packed soil. So let's be pessimistic and use 10x, thus it takes 30cm to absorb 90% of the energy, or right about one foot. This goes exponentially, so 1 ft absorbs 90%, 2 ft absorbs 99%, and 10 ft absorbs 99.99999999%.are the gamma rays and x rays absorbed in the soil and convert into heat or do they travel through the soil and out through the surface?
The main problems are in the safe and secure transport of the material and, more pervasively, the political factors around any proposed solution.Are there problems with putting all the used uranium rods world wide, in a very deep shaft and rather than trying to save them, back fill the shaft and let them go into melt down together?
Yes and yes (fission).is there a possibility that the more dense metals get pulled to the centre of the earth,
and that there is some kind of fission, fussion or power generation going on there. It seems strange to me that that the earth has stayed molten for so long?

I tried your suggestion - I find it interesting that at the center of the earth is the polar opposite transformation of at the sun. I am happy to find a natural realm to place fission.Yes and yes (fission).
Let me introduce you to a really neat website. It's called "Google".
Try Googling the phrase "why is the center of the earth so hot" and see what you get.
The shielding is not the hard part. From a technical standpoint there are a number of other concerns. Just for starters you have to get the material safely and securely to the site where it is to be interred. Then you have to make sure that it is going to stay interred. And all of this must be done in a manner that is cost effective. Finally, you have to deal with all of the political considerations and public concerns, both rational and irrational, that surround this topic.That is amazing that this problem can so easily be solved.
