NaI(Tl) Scintillation Detector

An energy-sensitive detector for identifying γ-ray and X-ray fluorescent radiation with high probability. The NaI(Tl) Scintillation Detector can record energy spectra, which can be calibrated, and measure the relative intensity of the radiation.

Incoming radiation causes a thallium-doped sodium iodide crystal to emit brief pulses of light. These are then converted into electrical pulses in proportion to the energy of the radiation, by means of a photomultiplier affixed to the apparatus. The crystal is protected against light penetrating from outside by a thin aluminium cover, whilst the photomultiplier is protected from interference by external magnetic fields by means of mu-metal shielding.
