The glass ceramic material of the present invention has the following composition, in weight percent,:

Biocompatible glass ceramic material

An inorganic vitreous detector material which in principle is composed of the three-component system consisting of metaphosphoric acid, aluminum metaphosphate, and zinc oxide, is used for the determination of the energy of particles of high energy. Such a material may additionally contain silicon dioxide and boron trioxide.

Inorganic vitreous detector material

A radio-photoluminescence dosimeter glass of low energy dependence, high sensitivity, and good resistance to weathering is composed of an activating silver compound such as silver metaphosphate and at least one metal fluoride, preferably of metals of groups I, II, III, and/or IV of the Periodic System. Such a glass may contain at least one further metal oxide, preferably an oxide of metals of groups I, II, and/or III of the periodic System, phosphorus pentoxide, and, if desired, nitrogen pentoxide.
