Beryllium (Be) is one of the most toxic metals. Because its production and utilization is now increasing, environmental pollution by Be is a serious environmental problem in Japan. Be is used as a metal, in BeCu and the other alloys, and in BeO ceramic products. On a global scale, Be enters the environment mainly from coal combustion.

As we have outlined, the amplifiion of the photocurrent in photomultipliers is done via a secondary emission. To optimize secondary emission, an electrode made of stainless steel, copperberyllium or nickel is coated by a socalled secondaryemissive material. These include alkaliantimonide, beryllium oxide, magnesium oxide, gallium phosphide, and arsenidegallium phosphide.
