A Scintillation Counter is a type of instrument used in laboratories to measure ionizing radiation. The three main parts of the equipment are a sensor called the scintillator, a photomultiplier tube, and an electronic amplifier. The sensor is usually made of a transparent crystal, plastic or organic liquid and undergoes fluorescence when struck by ionizing radiation. The photomultiplier tube, attached to the electronic amplifier quantify the amplitude of the signals produced by the photomultiplier.
Scintillation Counters are used to measure radiation in a variety of applications, such as:
