If I ingest a grain of sand size piece of the Chernobyl Reactor No.4 core
Couple naive questions:<p>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?<p>2. Why is Chernobyl still so dangerous if literally ingesting the spent fuel isn't super bad? Or is Chernobyl no longer dangerous?
