If I ingest a grain of sand size piece of the Chernobyl Reactor No.4 core
Couple naive questions:1. How does a piece of spent fuel end up in a "grassy bit of ground" outside the reactor? Thought it would have all melted in one big clump in the same spot?2. Why is Chernobyl still so dangerous if literally ingesting the spent fuel isn't super bad? Or is Chernobyl no longer dangerous?
