Enriched uranium doesn’t come from the earth, and after undergoing the fission process in the reactor, becomes highly radioactive for 10,000 years. They should have kept the core cooled so it wouldn’t melt down, but now that it is, they need to extract the core and reprocess it.
Fun fact: the radiation came from the Earth in the first place.
