'Green Rust' Can Protect Groundwater From Nuclear Waste, Researchers Report

摘要

A naturally occurring substance called "green rust" can help protect groundwater against radioactive contamination from stored reactor waste, Danish researchers have discovered. The researchers, led by geochemist Bo C. Christiansen of the University of Copenhagen, studied how green rust contained neptunium, a waste product from uranium reactors that can prove dangerous to human health if it seeps into groundwater - even millions of years after it is discarded at a repository.
