Scintillation Detectors
|
Scintillation dectectors use a solid or liquid material whose atoms are easily excited by the incoming radiation. These excited atoms emit visible light when they return to their ground state. Common materials used as scintillators are crystals of sodium iodide and certain plastics. If such a material is attached to one end of a photomultiplier tube the photons emitted by the scintillator can be converted to an electric signal. This pulse can, in turn, be sent to an electronic counter. The scintillator device is much more sensitive than the Geiger Counter, mainly because of the higher density of the detecting medium. Products & Services
Radiation detectors are used for medical diagnoses, radioactive dating measurements, and measurements of background radiation, activity levels and radiation doses.
