📖 Über Beryllium

An extremely stiff, lightweight, and toxic metal. It is transparent to X-rays, making it useful for X-ray tube windows. Beryllium is highly toxic if inhaled as dust or fumes, causing a serious chronic lung disease called berylliosis. Despite this, it is crucial in aerospace and nuclear applications.
