A radium barrier is a physical or chemical barrier designed to prevent the migration of radium, a radioactive element, into surrounding areas or groundwater. It is typically used in contaminated sites or nuclear facilities to contain and isolate radium to reduce the risk of exposure and contamination.
Radium is a chemical element; a compound has a minimum of two chemical elements.
