NCIt definition : A white colored, crystalline, inorganic compound that emits toxic fumes of beryllium
oxides upon heating. Beryllium oxide is widely used in industry due to its low density
and high thermal and electrical conductivity. It is used in high-technology ceramics,
electronic heat sinks, electrical insulators, high-power devices, high-density electrical
circuits, microwaves, X-ray windows, nuclear reactor fuels and for various aerospace
and military applications. Inhalation exposure to its dust irritates the nose, throat
and lungs and can cause pneumonitis. Prolonged exposure can result in a chronic beryllium
disease called berylliosis causing granuloma and fibrosis formation in the lungs.
Beryllium is associated with an increased risk of developing lung cancer. (NCI05);
