Can radiation be 'removed' or neutralised in anyway? (Even if just in theory)
gpt
By removing the radioactive isotopes producing it. Without this source, the radiation in an area will escape/be absorbed very quickly.

This can be done by sealing the material in concrete or something else dense enough to absorb all its radiation. The problems start when the source material is particulate or soluble, because then it can be carried off by rain and even make it into the water table. This is what has happened at Chernobyl.
