ስለ Beryllium
Beryllium is a relatively rare element occurring as a product of the spallation of larger nuclei. It is a hard, steel-gray metal that is remarkably stiff and lightweight. Beryllium is transparent to X-rays and is used in X-ray windows. Its compounds are toxic and can cause berylliosis.
ፕሮግራሞች
Aerospace materials, X-ray windows, nuclear reactors, springs, and non-sparking tools for use around flammable gases.
ሐቅ
Beryllium is transparent to X-rays, making it ideal for X-ray tube windows, and it was originally called 'glucinium' because its compounds taste sweet (though they are toxic).
