This categorization has led to the United States Government recommending that beryllium be stockpiled for use in the event of a national emergency. As of December 31, 2015, the National Defense Stockpile inventory of hot-pressed beryllium metal powder, structured beryllium metal powder, and vacuum-cast beryllium metal totaled 78 metric tons (t ...

Key Points. Anyone working with or around beryllium metal, ceramics, alloys, or salts is at risk of developing beryllium sensitization or disease from inhaling small particles. Very low concentrations of beryllium in air can cause sensitization and disease. People living near a plant that uses beryllium and families of workers have developed CBD.

An orphan radium-beryllium (Ra–Be) neutron source (Nuclear Chicago Corporation) detected inside a scrap metal ship-ping container, was seized and subjected to nuclear forensic analysis. Physical and chemical characterization methods were used before and after source dismantling. Non-Destructive Testing (NDT) proved to be most useful for ...

Pure beryllium and its metal alloys have applications in electrical components, tools, structural components for aircraft, missiles, and satellites, and other metal-fabricating uses.
