Abstract

A legacy of the nuclear industry that threatens many areas of the world is contamination by radioactive radium from the solid and liquid wastes left after extracting uranium from its ores. Here we describe a highly charged, synthetic clay that specifically removes radium and immobilizes it at room temperature for safe disposal. This material may prove to be useful in decontaminating drinking water wells and soils of this toxic isotope.
