That's similar to how I approach the original problem - if human knowledge has regressed to the point where we don't know where radioactive waste is stored nor how to recognise it, there are probably countless other problems, and hazards they we haven't considered. It's an interesting discussion in theory, but I'm unsure how important it is in practice.
