A scintillation detector is composed of two parts: scintillation crystal, and photoelectric converter for converting the (ultraviolet) UVvisible lights into electric signals. Alone, most elements from rows five and six of the periodic table exist as metals, so an additional element(s) is needed to form an ionic-covalent compound with a bandgap wide enough to suppress thermal excitation of electrons, yet still narrow enough to allow for the production of many ionization-induced electron-hole pairs upon a radiation interaction. X-rays, gamma-rays or corpuscular radiation, Devices sensitive to very short wavelength, e.g. A new type of direct reading semiconductor dosimeter has been investigated as a radiation detector for photon and electron therapy beams of various energies and gives many advantages, such as continuous monitoring during irradiation, immediate reading, and permanent storage of total dose after irradiation.
